Ukufakwa okungalungile kungaholela emlilweni, ukushaqeka kukagesi, noma ukulimala kwezinto ezisebenza ngogesi. Njalo qasha uchwepheshe.
Q2: Kubiza malini ukufaka isitolo se-NEMA 14-50?A: Izindleko ziyahlukahluka kakhulu, kusukela kumakhulu ambalwa kuya ngaphezu kwenkulungwane yamadola. Izinto zifaka indawo yakho, amanani osebenza ngogesi, ibanga ukusuka kuphaneli, futhi uma iphaneli yakho idinga ukuthuthukiswa. Thola izingcaphuno eziningi.
Q3: I-NEMA 14-50 izoshaja i-EV yami ngokushesha kangakanani?IMP: Lokhu kuncike eshajani ye-EV yakho kanye ne-EVSE (iyunithi yeshaja) oyisebenzisayo. AI-NEMA 14-50Isifunda singakwazi ukusekela amazinga okushaja ukusuka ku-7.7 kW kuya ku-9.6 kW. Lokhu kungengeza ibanga elingamamayela angu-20-35 ngehora lokushaja kwama-EV amaningi.
Q4: Iphaneli kagesi yendlu yami indala. Ngisengakwazi ukufaka i-NEMA 14-50?A: Mhlawumbe. Osebenza ngogesi udinga ukwenza "isibalo somthwalo" ukuze abone ukuthi iphaneli yakho inomthamo owanele yini. Uma kungenjalo, noma uma zingekho izikhala zama-breaker ezingenalutho, ungase udinge ukuthuthukisa iphaneli yakho, okuyizindleko ezengeziwe.
Q5: Ingabe i-NEMA 14-50 ephumayo ayinamanzi? Ingabe ingafakwa ngaphandle?A: OkujwayelekileIzitolo ze-NEMA 14-50awenzi amanzi. Ekufakeni kwangaphandle, kufanele usebenzise isitsha esilinganiselwe se-"Weather Resistant" (WR) kanye nesembozo esifanele sezulu "esisetshenziswayo" esivikela ipulaki ne-outlet ngisho nalapho okuthile kuxhunyiwe.
Q6: Ingabe kufanele ngikhethe ishaja ye-EV enezintambo eziqinile noma i-plug-in ye-NEMA 14-50 EV ishaja?IMP: Amashaja enziwe ngocingo oluqinile axhumeke ngqo kusekhethi, amanye ancamela ukusethwa unomphela kanye nokulethwa kwamandla okungaba ukuphakama kancane. I-plug-inAmashaja e-NEMA 14-50 EVnikeza ukuguquguquka okwengeziwe uma ufuna ukuhamba neshaja noma uyishintshe kalula. Zombili izinketho ezinhle uma zifakwe kahle. Ukuphepha nokuthobela amakhodi kuyisihluthulelo sanoma yikuphi ukukhetha.
Lokhu okuqukethwe okwezinjongo zolwazi kuphela futhi akuhlanganisi iseluleko esisebenzayo sikagesi. Ukufakwa kwe-NEMA 14-50 kuhilela amandla kagesi aphezulu (240V) futhi kufanele kwenziwe umuntu osebenza ngogesi oqeqeshiwe, onelayisensi ngokuhambisana nomthetho.Ikhodi Kagesi Kazwelonke (NEC)kanye nawo wonke amakhodi endawo. I-LinkPower ilahla noma yisiphi isibopho sokufakwa okungafanele ngokusekelwe kulo mhlahlandlela.
