Kusintha Kwakukulu mu 2023 National Electric Code Impacting Lighting

National Electrical Code (NEC) imasintha kamodzi pazaka zitatu zilizonse.Munkhaniyi, tikuwonetsa zosintha zinayi za kachitidwe ka code (kope la 2023 la NEC) zomwe zimakhudza kuyatsa ndi motere:

Kuwala kwa Horticultural

Kupewa zoopsa zina zomwe zingachitike m'makampani opanga zowunikira, Sec.410.184 imafotokoza kuti chitetezo cha GFCI chimafunikira pomwe kuyatsa kwamaluwa kumalumikizidwa ndi zingwe zosinthika pogwiritsa ntchito zolumikizira zolekanitsidwa kapena mapulagi.Kupatulako kwatsopano kumalola zida zowunikira zomwe zimaperekedwa ndi mabwalo opitilira 150V kuti zitetezedwe ndi chosokoneza chapadziko lapansi (GFCI) chomwe chimayenda pa 20mA m'malo mwa 6mA.

Mawaya ndi Zida Zoyikidwa Pamwambapa Malo Owopsa (Osankhidwa)

Ndime 511.17 ili ndi kusintha kwakukulu chifukwa tsopano ikukonzedwanso kukhala mndandanda wa mndandanda ndi zofunikira zowonjezera pazitsulo zolembedwera ndi zida zapansi (EGCs) zomwe zawonjezeredwa kusakaniza.Mawu akuti “Kalasi I” asinthidwa ndi “Zowopsa (Zosakayikitsa)” m'malo asanu, kuphatikiza mutu wa Gawoli, popeza dongosolo la magawo sagwiritsanso ntchito dzina la "Class I".Gawoli limakonzedwanso kuchokera pandime yayitali kukhala zinthu zisanu ndi zinayi zomwe zingagwiritsidwe ntchito, ndipo zofunikira zidawonjezeredwa kunjira zambiri zamawaya.

Zotengera, Zowunikira, ndi Zosintha

Zofunikira zachosokoneza chapadziko lapansichitetezo cha zolandilira mu (A) (4) zidakulitsidwa kuzunguliraku mu Sec.680.22 kuphatikiza zotengera zonse zovekedwa 60A kapena kuchepera mkati mwa 20 ft pakhoma la dziwe.Izi m'mbuyomu zinkangogwira ntchito ku 15A ndi 20A, 125V zotengera.Gawoli likufuna chitetezo cha GFCI pazida zapadera zomwe zimayikidwa pakati pa 5 ft ndi 10 ft chopingasa kuchokera mkati mwa makoma a dziwe.Chilankhulo chatsopano mu (B) (4) chimakulitsa chitetezo chofunikira powonjezera zofunikira za SPGFCI zomwe zilole kuti zida zogwirira ntchito pamwamba pa 150V kuti zitetezedwenso.

Class-2-Powered Emergency Lighting Systems

Sec.700.11 ya Class 2 wiring imapereka zofunikira pamagetsi awa.Gawo latsopanoli limayankha matekinoloje monga PoE ndi makina ena owunikira mwadzidzidzi omwe amagwiritsa ntchito mphamvu ya Gulu 2.Malamulo ena m'nkhani ino adilesi yamagetsi yamagetsi, ndipo Gawo latsopanoli limapereka zofunikira pamakina otsika kwambiri.
