1.in na ọkụ sekit iji belata ego nke oru ngo, na-ahọrọkarị 1P circuit breaker, mkpa ịṅa ntị na elu circuit breaker ga-leakage njem ọrụ, ga-ebipụ elu ike ọkọnọ;

2. Ndozi ikike iji gbochie ahịrị ndụ na akara efu na-ejikọta ya na ihe mberede ahụ (mgbe akara ndụ na akara efu na-ejikọta na 1P na-ewepụ eriri efu ma ghara ịkwụsị eriri ndụ), enwere ike iji ya mee ihe. 1P + N obere sekit ngwaọrụ, nke a na-ekwukarị DPN circuit breaker.

3. Maka ụlọ nke sekit nke sekit nke otu nha, enwere ọdịiche dị n'etiti 1P na 1P + N, nke mbụ nwere ikike nkwụsịtụ dị elu karịa nke ikpeazụ n'okpuru ọnọdụ mberede mberede.Ya mere, a na-atụ aro ka ị jiri eriri sekit 2P maka sekit dị mkpa na nlekọta na-arụ ọrụ ugboro ugboro na ọrụ ahụ, ma ọnụ ahịa ya dị elu.

Na mgbakwunye: 1P, 2P maka otu usoro, 3P, 4P maka nkeji atọ.

Mgbe ọ bụ nchekwa efu, naanị 1P, 3P nwere ike iji;Mgbe ọ bụ ala nchebe, ọ kacha mma iji 2P, 4P.

1P + N: a na-etinye ihe nchekwa ahụ naanị n'ahịrị oge, a na-ewepụkwa usoro ahụ n'otu oge ahụ mgbe emere ihe ahụ.
