Izinguquko Eziyinhloko ku-2023 National Electric Code Impacting Lighting

I-National Electrical Code (NEC) ibuyekeza kanye njalo eminyakeni emithathu.Kulesi sihloko, sizokwethula izinguquko ezine zalo mjikelezo wekhodi (uhlelo lwango-2023 lwe-NEC) olunomthelela wokukhanya kanje:

I-Horticultural Lighting

Ukugwema izingozi ezithile ezingaba khona embonini yezibani ze-horticultural, Isik.I-410.184 icacisa ukuthi ukuvikelwa kwe-GFCI kuyadingeka lapho ukukhanya kwe-horticultural kuxhunywe ngezintambo eziguqukayo kusetshenziswa izixhumi ezihlukanisekayo noma amapulagi okunamathiselwe.I-Exception entsha ivumela okokusebenza kokukhanyisa okuhlinzekwa ngamasekhethi angaphezu kuka-150V ukuthi zivikelwe ngesiphazamisi esisohlwini senjongo ekhethekile ye-ground-fault circuit (GFCI) ehamba ngo-20mA esikhundleni sika-6mA.

Izintambo Nezisetshenziswa Kufakwe Ngenhla Kwezindawo Eziyingozi (Ezihlukanisiwe).

Isigaba 511.17 sinoshintsho olubalulekile njengoba manje sesihlelwa kabusha saba ifomethi yohlu enezidingo ezengeziwe zokufakwa ohlwini kanye nezikhondatha eziyisisekelo zemishini (EGCs) ezingezwe emiksini.Igama elithi “Ikilasi I” lithathelwa indawo ngokuthi “Liyingozi (Kuhlukanisiwe)” ezindaweni ezinhlanu, okuhlanganisa isihloko salesi Sigaba, njengoba uhlelo lokuhlukanisa indawo lungasasebenzisi igama elithi “Ikilasi I”.Lesi Sigaba siphinde sihlelwe kabusha sisuka endimeni ende saya ezintweni zohlu eziyisishiyagalolunye ukuze zisebenziseke, futhi izidingo zengezwa ezindleleni eziningi zokufaka izintambo.

Izithako, Izibani, kanye Nokushintsha

Izidingo zeisiphazamisi sesifunda sephutha lomhlabaukuvikelwa kwezimpahla ku-(A)(4) kwanwetshwa lo mjikelezo kuSek.680.22 ukuze kufakwe zonke izitsha ezikalwe ngo-60A noma ngaphansi ngaphakathi kwama-20 ft odongeni lwechibi.Lokhu ngaphambilini bekusebenza kuphela ku-15A kanye ne-20A, i-125V yokungena.Lesi Sigaba sidinga ukuvikelwa kwe-GFCI kumishini ethile efakwe endaweni ephakathi kuka-5 ft no-10 ft ngokuvundlile kusukela ezindongeni zangaphakathi zechibi futhi.Ulimi olusha ngesi-(B)(4) lunweba isivikelo esidingekayo ngokungeza imfuneko ye-SPGFCI ezovumela okokusebenza okusebenza ngaphezu kuka-150V ukuya phansi ukuze nakho kuvikelwe.

I-Class-2-Powered Emergency Lighting Systems

Isiqephu esisha.I-700.11 yezintambo ze-Class 2 inikeza izidingo zalezi zinhlelo zokukhanyisa.Lesi Sigaba esisha sikhuluma ngobuchwepheshe obufana ne-PoE namanye amasistimu okukhanyisa izimo eziphuthumayo asebenzisa amandla e-Class 2.Eminye imithetho kulesi sihloko se-athikili yamasistimu kagesi kalayini, futhi lesi Sigaba esisha sihlinzeka ngezimfuneko zamasistimu ezimo eziphuthumayo ze-low-voltage.
