Intambo Elenga Phansi noma Eyehlisiwe Ngaphesheya Komgwaqo Wakho Noma Umgwaqo: Kungani I-TV Yekhebula 'Engenabungozi' noma Ulayini Wocingo Unganikwa Amandla Ku-7,200 Volts¶

Ukuphumela endleleni yakho ngemva kokuduma, isiphepho seqhwa, isivunguvungu somoya, noma i-snag yeloli likadoti ukuze uthole ucingo olumnyama oluwugqinsi olucwila imitha elingu-1 (amafidi angu-3) ukusuka etiyeleni kubhampa wakho - noma ilele buthule otshanini obumanzi ngaphandle kwenhlansi eyodwa, ukuncwina, noma ukufutha intuthu njalo ngonyaka" futhi i-Wi-Fi isavuliwe, futhi le ntambo inokufakwa kwenjoloba emnyama ewugqinsi kuyo (noma ingena ebhokisini le-Comcast/Spectrum/AT&T ohlangothini lwendlu yami), ngakho-ke i-TV yekhebula efile engenangozi noma ulayini wefoni ngizovele ngibambe induku yomshanelo wokhuni noma amagilavu okusebenza, ngiwuphakamise phezu kophahla lwami lwe-SUV, noma ngiwukhiphe ukuze ngiwukhiphe emshinini kagesi. uphenyo, lokho kucatshangelwa okuyimbangela #1 yokubanjwa ngogesi okwehlayo endaweni yokuhlala.

Kukhona izizathu ezintathu ezibulalayo zokuthi kungani kungabikho liso lomuntu - ngisho nomphathi welayini weminyaka engu-30 omi eceleni komgwaqo ngaphandle komtshina oseduze wamandla kagesi aphezulu ("tick tracer") kanye ne-fiberglass hot-stick - ingasho ngokubheka ukuthi intambo elengayo ephansi yomgwaqo wakho izokubulala yini lapho uthintana naye: 1. I-Remote Primary Cross-Energization ("Joint-Use Pole Contact") I-Three Blocks Away: Izigxobo zensiza zithwala 7,200-to-34,500-volt imigqa yokusabalalisa engenalutho engenalutho phezulu impela, 120/240-volt izintambo zikagesi yesibili phakathi, kanye Ezokuxhumana (Cable TV Coax, Telephone Copper, and Fiber-Optic) izintambo eziboshelwe ensimbi engenalutho Messenger Strand (support wire) 1.2 amamitha (4 amafidi) ngaphansi kwezintambo zikagesi. Uma igatsha lesihlahla liwa noma imoto ishayisa isigxobo amabhulokhi amane ezansi nomgwaqo ngaphandle komugqa owubonayo, intambo yamandla eyinhloko engu-7,200-volt* iwela phezu kwensimbi ye-telecom messenger noma i-metallic fiber armor. Ukuthi 7,200 volts ihamba buthule amakhilomitha ehle ngomucu wosekelo lwensimbi "okungenabungozi" Ikhebula le-TV yakho noma ulayini wefayibha ngqo ku-driveway yakho ngaphandle kokukhubekisa isinqamuleli sesiteshi esingaphansi. 2. Ukumboza Isimo Sezulu AKUKHO I-Insulation Kagesi: Ibhantshi lepulasitiki elimnyama (polyethylene weather-covering) phezulu izintambo zamandla ezidonsa kathathu kanye nentambo yesihlahla (spacer cable) yakhelwe ukuvikela kuphela intambo ye-aluminium ekukhanyeni kwelanga nasemvuleni - AYIlinganiselwe ukuze ivimbele isandla somuntu ekubanjweni ngugesi, futhi ukuchayeka elangeni kwe-UV kuyiqhekeka njengamagxolo esihlahla esomile ngakho-ke ama-arc amanje aqonde ngqo kumagilavu noma induku yokhuni emanzi. 3. Izintambo Eziphansi Azicishe Ziyinhlansi noma I-Arc ku-Asphalt noma Utshani: Amamuvi abonisa izintambo zamandla ezehlisiwe zizulazula njengodrako ovuthayo. Empilweni yangempela, itiyela elomile, ukhonkolo, nokungcola kunokubambezeleka kukagesi okuphezulu: 13,800-volt primary wire noma 240-volt service drop drop elele ngaphesheya komgwaqo ngokuvamile kuhlala 100% ithule, inganyakazi, futhi ayinanhlansi kuze kube yilapho isandla somuntu noma udladla lwenja luyithinta phansi futhi luyinikeza ukuqina.

(Ukuze uthole izinqubo zolayini wamandla owehlisiwe ovaleleke emotweni kanye nesinyathelo esingenzeka se-bunny-hop ukubaleka, bona Izintambo zikagesi ezehlisiwe kanye nogesi wemoto. Ukuze uthole izintambo ezihlezi ophahleni lwendlu noma kocingo lwe-chain-link, bheka Intambo kagesi ewile ocingweni lwendlu noma lwegceke futhi Amandla kagesi adukile ezilambuni zensimbi, amakhava emigodi yaseceleni komgwaqo, nokushaqeka okuhamba ngezinja, futhi sigcine umhlaba wethu izinombolo eziphuthumayo uhla lwemibhalo luyafinyeleleka.)

Yenza lokhu manje¶

1. Hlala okungenani amamitha angu-10 (amafidi angu-35) kusukela kunoma yiluphi ucingo olulengiswe phansi noma olulenga phansi - futhi ugcine izingane, izilwane ezifuywayo emigqeni, kanye nomakhelwane babuye ngokushesha.
2. Phatha 100% wezintambo eziphezulu (thick, thin, braided, flat, black-coated, or bare metal) njengoba kunikwe amandla ku-7,200+ volts kuze kube yilapho u-lineman wezinsiza ehlola futhi ebeka umugqa.
3. Uma ucingo luthinta uthango lwe-metal chain-link, isitimela esigada insimbi, igutter ye-aluminium, i-downspout, igatsha lesihlahla esimanzi, noma idamu, hlala okungenani amamitha angu-10 (amafidi angu-35) kusukela kubo bonke ubude balolo thango noma ichibi (a metal chain-link fence conducts lethal voltage for 300+ meters / 1,000+ feet down the block).
4. UNGALOKOTHI uthinte, uphushe, uphakamise, noma uphakamise ucingo olulenga kancane ngothi lomshanelo wokhuni, ipayipi le-PVC, ireki, igatsha lesihlahla, noma amagilavu enjoloba.
5. Ku-7,200 kuya ku-13,800 volts*, ugesi wamandla aphezulu uhamba kalula phakathi komswakama omncane, uthuli olungaphezulu, amanzi okhuni, noma ukuvanisha esibanjeni sokhuni somshanelo noma ipayipi le-PVC, ukhanyise ezandleni zakho nasesifubeni nge-millisecond. Kuphela okuhlolwe i-dielectric 100-kilovolt ngonyawo ngalunye lwe-fiberglass lineman's Hot-Stick esulwe nge-silicone engathinta umugqa ongaphezulu ngokuphepha.
6. UNGALOKOTHI ushayele imoto yakho noma iloli phezu kwentambo ewile elele emgwaqweni noma ngaphesheya komgwaqo wakho (and NEVER try to drive under a sagging wire that might snag your roof rack or antenna).
7. Kungani Ukushayela Phezu Kwentambo Ephansi Kuyingozi:
   • I-Hazard A (I-Mechanical Entanglement): Uma isondo lakho langaphambili ligingqika phezu kwentambo yensimbi eqinile noma ikhebula le-triplex, isondo eliphothayo noma i-brake caliper ngokuvamile ihhuka futhi isonga intambo ku-asili yakho noma inqola engaphansi. Njengoba imoto yakho iya phambili ngamamitha angu-2 (amafidi angu-6), ujikijela isigxobo sosizo noma isihloko sesimo sezulu sendlu ngobudlova ophahleni lwemoto yakho, uvaleleke ngaphakathi kwemoto enamandla.
   • I-Hazard B (I-High-Voltage Tire Blowout & Fire): Nakuba amathayi enjoloba equkethe i-carbon black futhi ekwazi ukuqhuba amandla kagesi aphezulu, ukugingqika ngokuqondile phezu 7,200V ulayini kubangela i-arc yamanje enkulu esidumbu sesondo esinebhande lensimbi, iqhuma amathayi futhi ithungele imoto ngomlilo.
8. Shayela u-911 (noma u-112 / 999) KANYE Nenombolo Yocingo Yokuxhumanisa Yezimo Eziphuthumayo engu-24/7 ye-Emergency Downed-Wire OKOKUQALA (ngisho noma uqinisekile ngo-99% ukuthi iyintambo ye-Cable TV, Ucingo, noma i-Fiber).
9. Kungani Kufanele Ushayele I-Electric Utility Okokuqala, Hhayi I-Comcast / Spectrum / AT&T / Verizon: Uma ushayela i-TV yekhebula noma inkampani ye-inthanethi ukuze ibike intambo ephansi yomgwaqo wakho, ikhompuyutha yabo yesevisi ihlela iveni lesevisi elivamile la "ngoLwesine oluzayo phakathi kuka-1:00 PM no-5:00 PM." Okubi nakakhulu, uma i-telecom ifika imithetho ye-telecom.29 CFR § 1910.268) yenqabela ngokuqinile ikhebula/uchwepheshe wefoni ukuthi athinte intambo edonswa phansi uma kukhona ithuba lokuthintana namandla kuze kube yilapho I-Electric Utility isusa isigxobo.
10. Ngokushayela ku-911 kanye ne-Emergency Dispatch ye-Emergency Utility yakho** kanye nokubika "Intambo Ephezulu Ephansi / Elenga Phansi Evimba Umgwaqo/Umgwaqo e- [Address] (Pole #[Number])", isisetshenziswa sikagesi sithumela isimo esiphuthumayo Inkinga (First-Responder Lineman) ngeloli lebhakede lamandla kagesi aphezulu ukuze ihlole intambo kagesi bese inqanyulwa noma iyivikele ngokuphepha phakathi namahora ambalwa.
11. Beka amakhoni ethrafikhi awolintshi agqamile, amathini kadoti, noma imoto emile (okungenani amamitha angu-10 / 35 amafithi emuva ekhanyise izibani eziyingozi) ukuze uxwayise amaveni okulethwa, abagibeli bamabhayisikili, nabagibeli bezithuthuthu ngaphambi kokuba kuhwalele.
12. Intambo emnyama elengayo elenga 1.2 kuya ku-2.5 amamitha (amafidi angu-4 ukuya kwangu-8) ngaphesheya komgwaqo noma indlela yokungena 100% ayibonakali uma kuhwalala noma ebusuku. Njalo ngenkathi yeziphepho, abashayeli bamabhayisikili, abagibeli bezithuthuthu, abagijimayo, kanye namaveni okulethwa e-Amazon/UPS abhekana nokufa ukunqunywa ikhanda kwentambo yezingubo noma ukuhlukumezeka kwentamo - noma ukudiliza izigxobo zikagesi ezibukhoma - ngokugibela noma ukushayela ikhebula elimnyama elingamakiwe. Yima endaweni ephephile eqhele ngamamitha angu-15 (amafidi angu-50) nethoshi ukuze uzulise izimoto ezizayo zime kuze kube yilapho amaphoyisa noma izicishamlilo ziphuma emgwaqweni.

Isigaba 1: Izigxobo zosizo zihlelwa kanjani ukusuka phezulu kuye phansi (And how 7,200 volts jumps into the "Communication Space")¶

Nakuba kufanele uphathe zonke izintambo ezehlisiwe njengezinamandla abulalayo, uqonde ukuthi umuntu waseNyakatho Melika (NESC C2) noma isigxobo sosizo samazwe ngamazwe sihlelwa ukusuka phezulu kuye phansi sikusiza ukuthi unikeze umbiko onembile ku-911 kanye ne-dispatcher yensiza kagesi ukusuka ebangeni eliphephile lamamitha angu-15 (amafidi angu-50) usebenzisa i-zoom yekhamera yefoni yakho:

I-Anatomy Ebonakalayo Nekagesi Yepali Yokusetshenziswa Okuhlangene (Phezulu ukuya Phansi)¶

Isigaba sesi-2: Kungani amalambu endlu yakho ENGAVULA kuyilapho intambo yamandla ebukhoma ilele ngaphesheya komgwaqo wakho.¶

Inganekwane yesibili eyingozi kakhulu mayelana nezintambo zikagesi ezehlisiwe yilena: "Ngibheke endlini yami futhi izibani zethu, isiqandisi, ne-TV konke kusebenza ngendlela evamile, okufakazela ukuthi intambo eyehlisiwe egcekeni lami AKUSIYO intambo yamandla kagesi."

Nazi izizathu ezine zobunjiniyela bukagesi kungani intambo ebekwe endleleni yakho ingaba 100% iphile ngogesi obulalayo kuyilapho indlu yakho isenamandla aphelele: 1. EYODWA Kuphela Kwababili 120V Imilenze Eshisayo (or the Neutral) Yakho 120/240V I-Triplex Drop Broke: - Ukwehla kwenkonzo kagesi ekhaya lakho (Triplex) iqukethe izintambo ezintathu eziphothene ndawonye: Hot Leg L1 (120V), Hot Leg L2 (120V), kanye Bare Neutral/Messenger Wire. - Uma igatsha eliwayo linqamula i-Bare Neutral support wire* (ngakho yonke ikhebula elisindayo le-triplex lishona phansi ku-driveway yakho ngaphandle kokuphuka L1 futhi L2), NOMA uma eyodwa kuphela 120V ucingo olushisayo izinyembezi ziyaxebuka esigxotsheni sesigxobo kanti enye 120V umlenze uhlala uxhumekile, uhhafu noma wonke amalambu angu-120-volt nezitolo ezingaphakathi kwendlu yakho zizoqhubeka zikhazimula, kuyilapho aphukile bukhoma 120V ucingo (capable of delivering 400+ amps before the transformer fuse blows) iphumule ngqo ku-driveway yakho. 2. Linda-Isimo Ekungathathi hlangothi Okuphukile ("The Open-Neutral Voltage Swing"): - Uma intambo engenalutho eyisiliva engathathi hlangothi yeconsi lakho le-triplex ishaya emoyeni, isiphetho esiphukile esinamathiselwe esihlokweni sezulu sendlu yakho siba namandla abulalayo 120 Volts ngomthwalo obuyayo wesiqandisi sakho kanye nesithando somlilo, ngenkathi ungaphakathi endlini yakho, amanye amagumbi ayafiphala 60V namanye amagumbi ayafika 180V (izivikeli zokukhuphuka kokubhema kanye nemishini). 3. Yindawo Yokulahla Isevisi Kamakhelwane Wakho, I-Streetlight Feed, noma Indawo Yebhasi Yesibili: - I-pole-top transformer eyodwa ivamise ukuphakela izindlu ezi-4 kuye kweziyi-8 ngompompi bamaphakathi ne-span noma ngamabhasi esibili. Intambo ewele phansi egcekeni lakho kungenzeka iphakela isekethe yesibani sasemgwaqweni noma igaraji likamakhelwane wakho kuyilapho ukwehla kwakho kwesevisi kuhlala kungathintwa. 4. Iziphambeko Zokuvimba Okuphezulu Kwendawo ("Hi-Z Faults") ku 7,200V Imigqa Eyisisekelo AYIQHUBEKI I-Substation Breaker: - Abanikazi bezindlu bacabanga ukuthi uma 7,200-volt oyinhloko yamandla kagesi ihlwitha futhi iwela ku-driveway, esihlahleni, noma ikhebula le-telecom, isebenza njengesekhethi yasendlini futhi ngokushesha igibelisa i-breaker yesifunda esiteshini esisetshenziswayo. - Iqiniso Legridi: Isiphakeli sesiteshi esingaphansi siklanyelwe ukuthwala 400 kuya ku-600+ Amps (enough power to run 1,500 homes simultaneously) ngaphandle kokukhubeka. Uma intambo ephukile engu-7,200-volt iwela ku-asphalt owomile, ukhonkolo, utshani, noma igatsha lesihlahla, ukumelana nomhlabathi kukhawulela iphutha lamanje ukuze libe ku-10 kuphela kuya ku-50 Amps. Kukhompuyutha yesiteshi esingaphansi, ama-Amps angu-30 engeziwe abukeka afana nomakhelwane abayishumi abavula iziyondisi zabo zomoya noma amashaja e-EV - ngakho-ke isiphazamisi sesiteshi esingaphansi ANGEKE sihambe, futhi igumbi lokulawula lensiza line-alamu ezenzakalelayo engu-ZERO lapho intambo engu-7,200V ilele phansi uze ushayele ku-911.

Isigaba sesi-3: Kuthiwani uma ucingo olulenga kancane lubanjwe yiloli likadoti, iveni elihambayo, noma igatsha lesihlahla futhi lidonsa indlu yakho (The "Weatherhead Tear-Off" Hazard)?¶

Imvamisa ngemuva kwesivunguvungu noma lapho iloli lebhokisi elide lokulethwa (U-Haul, Amazon, FedEx, or Municipal Garbage Truck) ishayela phansi ngomgwaqo wendawo yokuhlala, ikhona eliphezulu lebhokisi leloli lihosha ukulenga okuphansi Triplex Electric Service Drop noma Coax/Fiber Drop ukuwela umgwaqo ukuya endlini yakho.

I-Triage Esheshayo Yesakhiwo Nogesi Lapho Intambo Idonswa Iqine Imelene Nendlu Yakho¶

   • Iklebhula **ibhokisi le-Aluminium Electric Meter Box yangaphandle phakathi nendawo yesitini noma i-vinyl siding **; futhi
   • INGOZI YOMLILO EFIHLEKILE ODONGENI: Ukudonsa isokhethi yemitha yangaphandle iye phansi kudonsela phansi isindayo 2/0 i-aluminium noma ithusi Ukungena Kwesevisi (SE) Ikhebula eligijima ngaphakathi kodonga lwakho liye phezulu kwe-Main Indoor Circuit Breaker Panel, idonsa 200-Amp Main Lug Conductors* engafakwanga mshini** iqondane ngqo nendandatho yensimbi ecijile ye-breaker box (which sits BEFORE your main breaker and cannot trip).
4. Uma Ibhokisi Lakho Langaphandle Lemitha Kagesi, Ipayipi Lomzila, noma Isihloko Sesimo Sezulu Igobile, Idonswa Yasuka Odongeni, Noma Ihiya:
5. UNGATHI uthinte ibhokisi lamamitha langaphandle, i-aluminium side, noma ama-downspout ensimbi (the entire metal skin of the meter box and aluminum siding can be energized at 120/240V).
6. UNGAWUTHInti umnyango wephaneli yephaneli yensimbi yakho yasendlini uma uzwa ukubhayiza, ukuklayeka, noma iphunga elivuthayo i-bakelite/ipulasitiki eduze kwephaneli.
7. Phuma endlini ngokushesha futhi ushayele i-911 kanye ne-Electric Utility ukubika "I-Energized Service-Mast Pull-Out / Isokhethi Yemitha Elimele ku [Address]." I-lineman yensiza izosika izintambo ezintathu ezingaphezulu esigxotsheni (de-energizing the mast), ngemva kwalokho osebenza ngogesi onelayisensi angakwazi ukuphinde abophe insika kanye nebhokisi lemitha ngaphambi kokuba insiza ixhume kabusha amandla.

Izinombolo zezimo eziphuthumayo zesifunda kanye nezinqubomgomo ze-ejensi¶

Imibuzo evame ukubuzwa¶

Kuthiwani uma ucingo oluwele phansi luwela emotweni yami ngenkathi ngihlezi ngaphakathi kuyo endleleni yami yokungena?¶

Uma intambo engaphezulu iwela emotweni yakho ngenkathi ungaphakathi, **HLALA PHAKATHI EMOTWENI**. Inqobo nje uma uhlezi ngaphakathi kwekhabhinethi ngaphandle kokuthinta amafreyimu eminyango yensimbi, umzimba wemoto yakho usebenza njengendawo ephephile **Ikheji le-Faraday** (ngisho noma intambo inikwe amandla angu-7,200 volts). Gcoba uphondo lwakho, wehlise iwindi kancane ukuze umemeze kwababukele ukuthi **bahlale okungenani amamitha angu-10 (35 amafidi) babuye**, bese ushayela u-**911** kumakhalekhukhwini wakho ukuze utshele umthumeli-mpahla ukuthi uvaleleke emotweni ngaphansi kwentambo eyehlisiwe ukuze isisetshenziswa sikagesi sivale ulayini. **UNGALINGE uphume emotweni unyawo olulodwa luphansi ngenkathi isandla sakho noma olunye unyawo luthinta imoto** (`doing so bridges the 7,200-volt vehicle body directly to the earth through your heart`). UKUPHELA kwesizathu sokuphuma emotweni ngaphambi kokuba insiza iqede ulayini siwukuthi **imoto isha umlilo**: uma ubona intuthu noma amalangabi, vula umnyango ngaphandle kokuthinta uhlaka lwensimbi, weqa izingalo zakho phezu kwesifuba sakho, **gxuma kucace ukuze zombili izinyawo zishaye phansi ngaso leso sikhathi (`never touching the car and ground simultaneously`)**, kanye no-*shova noma u-bunny-hop izinyawo zombili zicindezelwe ngokuqinile ndawonye** okungenani amamitha angu-*10 kuya ku-15 (35 kuya ku-50 amafidi)** (`see` [Izintambo zikagesi ezehlisiwe kanye nogesi wemoto](../accidents/downed-power-lines-and-vehicle-electrocution.md)).

Ngingawubona kanjani umehluko ukusuka kumamitha ayi-15 (amafidi angama-50) phakathi kwendlu yami 120/240V Ukwehla Kwesevisi Kagesi (Triplex) kanye nentambo yami ye-Cable TV/Fiber?¶

Nakuba ungafanele **ungalokothi uthinte noma iyiphi intambo** (ngoba ulayini we-Cable TV/Fiber unganikwa amandla anqamule ku-7,200V ukusuka ezansi nomgwaqo), ungakwazi ukunikeza i-911 dispatcher incazelo enembile ngokubheka **izimpawu zendawo ezimbili ezibonakalayo ukusuka kumamitha angu-15 (amafidi angu-50) emuva**: 1. **Bheka Lapho Intambo Inamathisela Endlini Yakho:** Yakho **Inkonzo Kagesi Yehla (`120/240V`)** inamathela phezulu**kumugqa wophahla / ezindlebeni** kusivalo sepayipi lensimbi eligobile (`the "Weatherhead"`) eyehla iqonde odongeni olungaphandle ingene **ngilazi eyisiyingi/iDijithali Yemitha kagesi Ibhokisi** lakho. Ngokuphambene, **I-TV yekhebula (`Coax`), Ucingo, kanye nezintambo ze-Fiber-Optic** zinamathisele ehhukuni lensimbi elincane ku-fascia yakho noma uhlangothi bese zehlela ebhokisini lepulasitiki elincane **elincane elimpunga noma eli-tan (`NID`) ekuphakameni okhalweni**, ngaphandle kokuxhumeka kumitha kagesi. 2. **Bheka Ukuma Kwentambo Ngokwayo:** Ukulahla Kwesevisi Kagesi (`Triplex`)** iqukethe **izintambo ezintathu ezihlukene eziphothene ndawonye njengentambo ezungezayo** (izintambo ezimbili eziboshwe emnyama ezisongwe ocingweni olulodwa olungenalutho, olucwebezelayo lwe-aluminium/yensimbi). A **I-TV yekhebula, Ucingo, noma i-Fiber drop** iyintambo** eyodwa ebushelelezi emnyama** (`round or flat like a ribbon`).

Kungani isisebenzi noma isicishamlilo sibeke izigaxa eziwolintshi eduze kwentambo ewile egcekeni lami bese sishayela ngaphandle kokuyicosha?¶

Ngesikhathi kunesivunguvungu esikhulu noma isiphepho seqhwa lapho izintambo ezingu-300+ zehle edolobheni, izinsiza zikagesi zisebenzisa isistimu yokuhlola izimo eziphuthumayo enezigaba ezimbili: - **Isigaba 1 (Abasebenzi "Yenza-Uvikeleke / Sika-futhi-Sula"):** Okokuqala, oyedwa **"I-Troubleman" noma "I-Wire-Guard / Cut-Clear"** ohamba ngendiza** ufika ngeloli elincane lebhakede. Bahlola intambo eyehlisiwe ngomtshina wamandla kagesi aphezulu: **(a)** uma kuyintambo yamandla eyinhloko noma yesibili enikwe amandla, bavula i-pole fuse cutout (`"popping the cutout barrel"`) noma usike ucingo esigxotsheni ukuze ucezu olubekwe otshanini bakho lufe* ngogesi ongu-100% (`isolated`)**, qopha isiphetho esisikiwe, bese ufaka izigaxa ezisawolintshi noma itheyiphu yokuqapha ephuzi nxazonke; noma **(b)** uma kuwucingo olufile (`Comcast/AT&T`) ikhebula, bayisongele phansi esigxotsheni bese befaka ithikithi lenkampani yezokuxhumana. - **Isigaba 2 (Iqembu Lokwakha Kabusha Umugqa):** Amahora noma izinsuku kamuva, ithimba eligcwele labantu abangu-4 lifika lizohlehlisa futhi liqinise ucingo lubuyele esigxotsheni. Ngisho noma ucingo lunetheyiphu yesexwayiso ephuzi kuyo, **ungalinge unyakaze noma uthinte intambo ewele phansi ngokwakho**, ngoba i-backfeed engafanele evela kujeneretha kaphethiloli ophathwayo kamakhelwane ingaphinda inike amandla ulayini owehlisiwe ukusuka ohlangothini lwendlu.

Ingabe isiphehlisi sikaphethiloli esiphathwayo sikamakhelwane singavuselela ngempela intambo kagesi eyehlisiwe "efile" emgwaqeni wethu ngo-7,200 volts?¶

Yebo - lokhu kubizwa ngokuthi **Transformer Backfeed**, futhi kungenye yezingozi ezibulala kakhulu kubo bobabili abahlali kanye nabasebenza ngemishini ngesikhathi sokucima kukagesi. Lapho umninikhaya exhuma ngokungemthetho ijeneretha ephathekayo engu-240-volt endaweni yakhe yokomisa (`using a "suicide cord"`) noma baxhume ijeneretha kuphaneli yabo yebreaker **ngaphandle kokucisha i-Main 200-Amp Breaker yabo (`or without a code-compliant Mechanical Interlock / Transfer Switch`)**,**240 volts wejeneretha ageleza emuva aphume endlini akhuphukele kusiguquli esingaphezulu kwesigxobo somgwaqo**. Ngenxa yokuthi i-transformer isebenza kuzo zombili izinhlangothi, isiguquli-sigxobo esingaphezulu **izinyathelo ezithi 240 volts PHEZULU sibe ngu-7,200 kuya ku-13,800 volts** bese siyiphakela ngqo ocingweni oluwile elele emgwaqweni.

Yibuphi ubude obuncane obungokomthetho okufanele izintambo zikagesi nezintambo ze-TV zilengiswe ngenhla kwe-driveway yami nomgwaqo?¶

Ngaphansi kwe-**Ikhodi Kazwelonke Yokuphepha Kagesi (`NESC Table 232-1`)** e-United States (kanye nemithetho efanayo ethi **CSA C22.3** e-Canada), izintambo eziphezulu kufanele zigcine ukuvuleka okuqinile okuqinile okuqondile ngaphezu komhlaba ngisho nosuku olushisa kakhulu lwasehlobo (lapho izintambo zikhula futhi zicwila): - **Ngaphezu Komgwaqo Womphakathi, Umgwaqo, noma Umhubhe (Kungaphansi Kwethrafikhi Yamaloli):** Okungenani **`4.7 meters (15.5 feet)`** yezintambo zokuxhumana ezingavalekile/i-triplex, kanye **`5.6 meters (18.5 feet)`** yezintambo zamandla eziyisisekelo ezingenalutho. - **Ngaphezu komgwaqo wokuhlala:** Okungenani **`3.5 meters (11.5 feet)`** yokwehliswa kokuxhumana/yesevisi (noma `4.7 meters / 15.5 feet` uma amaloli/ama-RV esebenzisa indlela yokungena). - **Ngaphezulu Kweyadi Yabahamba Ngezinyawo Kuphela noma Umgwaqo Waseceleni (Azikho Izimoto):** Okungenani **`2.9 to 3.7 meters (9.5 to 12.0 feet)`**. Uma noma iyiphi intambo ewela indlela yakho yokungena noma yomgwaqo incipha kunalezo zimo eziphakeme, shayela isevisi noma umasipala `311` Umhloli ukuthi aphinde aqinise i-span mahhala ngaphambi kokuthi iloli elilethayo lisiphule.
