Iibhokisi yokusasazwasisixhobo esiphambili kwinkqubo yamandla yokufezekisa usasazo, ulawulo kunye nokukhuselwa kwamandla ombane, kwaye sisetyenziswa kakhulu kwimveliso yemizi-mveliso, izakhiwo zorhwebo, ubunjineli bukamasipala kunye nezibonelelo zangaphandle kunye nezinye iimeko. Kwizityalo zoshishino, ibonelela ngombane ozinzileyo kwizixhobo zezigaba ezintathu ezifana nezixhobo zoomatshini, iifeni kunye nemigca yokuhlanganisa. Iivenkile ezinkulu, izakhiwo zeeofisi kunye namaziko edatha ayisebenzisa ukufezekisa usasazo lwamandla olucwangcisiweyo lokukhanyisa, umoya opholileyo kunye nezixhobo zegumbi leekhompyutha. Kwiindawo zangaphandle ezifana nokukhanyisa ezindleleni, kwiindawo zokwakha, kunye nokulinganisa iinqwaba zokutshaja, iibhokisi zokusasaza ezingangeni mvula kunye nezinganyangekiyo zidla ngokusetyenziswa ukuqinisekisa ukusebenza ngokukhuselekileyo emoyeni ovulekileyo. Ukongeza, iindawo zokuhlala, iiworkshops zefektri, kunye neeprojekthi zokuhlaziya umbane nazo azinakwenza ngaphandle kweebhokisi zokusasaza zolawulo oluphakathi ukuqinisekisa usasazo olufanelekileyo lwemithwalo yamandla kunye nokuhlangabezana neemfuno zokusebenza ezizinzileyo zezixhobo zamandla aphezulu zezigaba ezintathu ze-480V.
Isakhiwo sangaphakathi sisebenzisa ikakhulu uyilo oluyimodyuli, oluquka umzimba webhokisi, iyunithi yomgca ongenayo, iyunithi yokusasaza, izinto zokukhusela kunye nenkqubo yocingo. Umzimba webhokisi wenziwe kakhulu ngepleyiti yentsimbi eqengqelekayo ebandayo okanye intsimbi engagqwaliyo. Uhlobo lwangaphandle lunomgangatho wokhuseleko lwe-NEMA 3R, olunokuthintela imvula, uthuli kunye nezinto zangaphandle ukuba zingangeni. Icandelo lomgca ongenayo lixhotyiswe ngeswitshi ephambili, kunye ne-circuit breaker eqhelekileyo esebenza njengolawulo oluphambili lokufezekisa ukhuseleko lokuvala isekethe kunye nokugqithisa. Ngaphakathi, amandla ombane asasazwa ngeebhasi zekopolo. Kufakelwe iiswitshi ezininzi zokuqhekeka kwesebe, kwaye isebe ngalinye lixhotyiswe nge-circuit breaker ukubonelela ngokhuseleko lwe-short-circuit kunye nokugqithisa kwimigca yesebe. Ibhokisi ixhotyiswe ngee-wire bars ezingathathi cala kunye nee-grounding bars ukuqinisekisa ukhuseleko lombane. Kwangaxeshanye, indawo efanelekileyo yocingo igciniwe, kwaye iintambo zicwangciswe ngendlela emiselweyo ukunciphisa uphazamiseko kunye nemingcipheko. Isakhiwo sisonke sincinci kwaye ukhuseleko luthembekile. Ayinakufezekisa kuphela umbane we-multi-channel kodwa ikwanceda ukugcinwa nokulungiswa ngokukhawuleza, iqinisekisa ukunikezelwa kombane okuqhubekayo nokuzinzileyo kwiimeko ezahlukeneyo.
