Faka umthofu ohlukile wokusekela izinsimbi zejoka. Uma ingqikithi ithinta ngephutha i-clamp engenhla futhi ibangele iphutha lesisekelo lamaphuzu amaningi, i-fault current izozungeza kuphela ngaphakathi kwe-core kanye nokuhlanganisa i-clamp. Ngaphandle komthofu ohlukile, akukho okwamanje okuzogeleza ngomthofu oyinhloko oyisisekelo, okungase kuholele ekutheni abasebenzi bezokunakekela bakholelwe ngephutha ukuthi alikho iphutha. Ngokufaka umthofu ohlukile, noma yikuphi ukuthintana phakathi kwenkambo kanye ne-clamp kuyokwenza iluphu emithonjeni emibili yangaphandle yaphansi, okuvumela amandla aphansi ukuthi abonakale ngokunembile ngaphandle.
Misa i-core grounding shunt phakathi nendawo yejoka. Ngalokhu kubekwa, kungakhathaliseki ukuthi ikuphi indawo yamabholithi avikelayo kumabhande ethayi yejoka noma indawo yephuzu lokumisa iphutha, i-voltage ephezulu eyenziwe ku-loop izoba yi-1/4 kuphela ye-voltage yokujika. Ngakho-ke, umthamo omkhulu wamanje wokumisa uzokhawulelwa kuma-ampere ambalwa, aphansi kakhulu kunalapho i-grounding shunt ibekwa kwezinye izikhundla.
Uma izithiyo zokufakwa kwenkambu zidinga ukuthi i-core grounding shunt ibekwe kwenye indawo, amabhawodi avikelayo amabhande esibopho sejoka kanye ne-grounding shunt kufanele kumiswe ngokuphambana ngokuphambene ukuze kuvinjelwe ukukhiqizwa kwamagagasi amaningi.
