Ohereza imeriNka insinga z'amashanyarazi eshatu cyangwa enye zingana na volt 600, 90 deg.C. ahantu humye cyangwa hatose.
Byemejwe byumwihariko gushyirwaho mumigozi ya kabili ku ngingo ya 340 ya NEC.Ubwoko bwa insinga za TC ziremewe gukoreshwa mubyiciro I Icyiciro cya 2 ahantu hashobora guteza inganda muri NEC.Intsinga zirashobora gushyirwaho mumuyaga wubusa, mumihanda cyangwa gushyingura mu buryo butaziguye, ahantu hatose cyangwa humye.Intsinga zose iyo zikoreshejwe ukurikije NEC, zujuje ibisabwa na OSHA.
Uyobora umugozi ashobora kuba umuringa cyangwa aluminium cyangwaaluminium.Umubare wa cores urashobora kuba 1, 2, 3, kimwe na 4 na 5 (4 na 5 mubisanzwe ni insinga nke za voltage).
Intwaro ya kabili irashobora kugabanywamo ibyuma byuma byuma hamwe nicyuma cya kaseti, hamwe nibikoresho bitari magnetiki bikoreshwa mumashanyarazi ya AC imwe.
Ubwubatsi:
Imiyoboro y'umuringa ihagaze, XLP (Yambukiranya Polyethylene) irinze, Uburyo bwa 1 - Imbonerahamwe E1 cyangwa E2 ibara ryanditseho amabara, cyangwa uburyo bwa 4 bwerekanwe.Imiyoboro ikinguye yashizwemo numuyoboro wumuringa uhagaze mu ntera imwe, kaseti ya kabili, ikoti ya PVC (Polyvinyl Chloride), hejuru yacapwe.
Ibipimo:
Abayobora bahuza na ASTM B-3 & B-8.
Abayobora kugiti cyabo bahuye na UL Standard 44, kandi byemewe nkubwoko XHHW-2.
TC Ubwoko bwa Tray Cable ku ngingo ya 340 ya NEC.
Intsinga zibereye izuba riva.
Intsinga zagenewe gutsinda ibizamini bya flame ya IEEE-383 & IEEE-1202.
Intsinga zujuje ibisabwa na ICEA S-95-658 / NEMA WC70.
