3. Iingenelo zoKhuseleko zokusebenzisa iSwitshi yokuHlukana nomthwalo ngexesha loLondolozo kunye neeNgxaki

Imisebenzi yokugcinwa kombane ibandakanya umngcipheko omkhulu wokhuseleko, ingakumbi xa kusetyenzwa iinkqubo ze-voltage ephezulu okanye zamandla aphezulu. Ukunika amandla ngengozi ngexesha lokulungiswa kunokubangela ukwenzakala okukhulu, umonakalo kwizixhobo, okanye ixesha lokungasebenzi.

Ukufaka iUkutshintsha Ukuzahlula Komthwalokunceda ukunciphisa le mingcipheko ngokubonelela ngendawo ethembekileyo yokuqhawula phakathi komthombo wamandla kunye nomthwalo wombane. Oku kuqinisekisa ukuba abasebenzi bokulungisa banokusebenza ngokukhuselekileyo kwizixhobo zombane emva kokuba iswitshi icinyiwe.

Iiswitshi ezininzi zokwahlukanisa ziyaxhasaukutshixa/ukuthega (iLOTO)iinkqubo. Oku kuvumela iingcali ukuba zitshixe iswitshi kwindawo ethi OFF kwaye zincamathisele iithegi zesilumkiso, ukuthintela ukuphinda kuqhagamshelwe kwakhona okungagunyaziswanga okanye ngengozi ngelixa kusenziwa umsebenzi wokulungisa.

Kwiimeko ezingxamisekileyo, ukukwazi ukwahlula umbane ngokukhawuleza nako kubaluleke kakhulu. Abaqhubi banokuqhawula izixhobo ngokukhawuleza ukuthintela umonakalo ongakumbi okanye ukunciphisa iingozi ezifana nokushisa kakhulu, iimpazamo zombane, okanye iingozi zomlilo.
