Impinduka nyamukuru muri 2023 Kode yigihugu y amashanyarazi Amashanyarazi

Amategeko y’igihugu y’amashanyarazi (NEC) avugurura inshuro imwe buri myaka itatu.Muri iyi ngingo, tugiye kumenyekanisha impinduka enye ziyi code cycle (2023 integuro ya NEC) itara ryerekana ni nkibi bikurikira:

Amatara y'imboga

Kugira ngo wirinde ingaruka zimwe zishobora kubaho mu nganda zimurika mu buhinzi, Sec.410.Ibidasanzwe bishya byemerera ibikoresho byo kumurika bitangwa nizunguruka zirenga 150V kurindwa hamwe nurutonde rwihariye-rufite intego-yubutaka bwumuzunguruko (GFCI) igenda kuri 20mA aho kuba 6mA.

Amashanyarazi n'ibikoresho byashyizwe hejuru Ahantu hateye akaga (Bishyizwe hamwe)

Igice 511.17 gifite impinduka zikomeye kuko ubu cyongeye guhindurwa muburyo bwurutonde hamwe nibindi bisabwa kubikoresho byashyizwe ku rutonde hamwe nuyobora ibikoresho (EGCs) byongewe kuvangwa.Ijambo "Icyiciro cya I" ryasimbuwe na "Hazardous (Classified)" ahantu hatanu, harimo n'umutwe w'iki gice, kuko sisitemu yo gutondekanya zone itagikoresha izina rya "Icyiciro cya mbere".Iki gice nacyo cyongeye kuvugururwa kuva mu gika kirekire mu bice icyenda byurutonde kugirango bikoreshwe, kandi ibisabwa byongewe muburyo bwinshi bwo gukoresha insinga.

Ibyakirwa, Luminaire, na Switch

Ibisabwa kuriikosa ryumuzungurukokurinda ibyakirwa muri (A) (4) byaguwe iyi cycle muri Sec.680.22 gushiramo ibyakiriwe byose byapimwe 60A cyangwa munsi ya metero 20 zurukuta rwa pisine.Ibi mbere byakoreshwaga gusa kuri 15A na 20A, 125V yakira.Iki gice gisaba uburinzi bwa GFCI kubikoresho byihariye byashyizwe mu gice kiri hagati ya metero 5 na metero 10 utambitse uhereye kurukuta rwimbere rwa pisine.Ururimi rushya muri (B) (4) rwagura uburinzi busabwa wongeyeho SPGFCI ibisabwa bizemerera ibikoresho bikora hejuru ya 150V kubutaka nabyo birindwa.

Icyiciro-2-Bikoreshejwe byihutirwa byo kumurika

Umutekano mushya.700.11 kuri wiring yo mucyiciro cya 2 itanga ibisabwa kuri sisitemu yo kumurika.Iki gice gishya kivuga ku ikoranabuhanga nka PoE hamwe n’ubundi buryo bwo gucana byihutirwa bukoresha ingufu zo mu cyiciro cya 2.Andi mategeko muriyi ngingo aderesi yumurongo wa voltage sisitemu, kandi iki gice gishya gitanga ibisabwa kuri sisitemu yihutirwa ya voltage.
