Iibhokisi lokusabalalisaiyithuluzi eliyinhloko ohlelweni lwamandla lokuqaphela ukusatshalaliswa, ukulawulwa kanye nokuvikelwa kwamandla kagesi, futhi isetshenziswa kabanzi ekukhiqizweni kwezimboni, ezakhiweni zezentengiselwano, ubunjiniyela bomasipala kanye nezikhungo zangaphandle kanye nezinye izimo. Ezitshalweni zezimboni, inikeza ukunikezwa kwamandla okuzinzile kwemishini yezigaba ezintathu njengamathuluzi omshini, amafeni kanye nemigqa yokuhlanganisa. Izitolo ezinkulu, izakhiwo zamahhovisi kanye nezikhungo zedatha ziyisebenzisa ukufeza ukusatshalaliswa kwamandla okuhlukaniswe ngezindawo zokukhanyisa, imishini yokupholisa umoya kanye nemishini yamakamelo ekhompyutha. Ezindaweni zangaphandle ezifana nokukhanyisa emgwaqweni, izindawo zokwakha, kanye nokulinganisa inqwaba yokushaja, amabhokisi okusabalalisa angangeni emvula namelana nokugqwala avame ukusetshenziswa ukuqinisekisa ukusebenza okuphephile emoyeni ovulekile. Ngaphezu kwalokho, imiphakathi yokuhlala, ama-workshop efektri, kanye namaphrojekthi okuvuselela amandla nawo awakwazi ukwenza ngaphandle kwamabhokisi okusabalalisa okuphathwa okuphakathi ukuqinisekisa ukusatshalaliswa okufanele kwemithwalo yamandla nokuhlangabezana nezidingo zokusebenza okuzinzile kwemishini yamandla aphezulu yezigaba ezintathu engu-480V.
Isakhiwo sangaphakathi sisebenzisa kakhulu ukwakheka kwe-modular, okuhlanganisa kakhulu umzimba webhokisi, iyunithi yomugqa engenayo, iyunithi yokusabalalisa, izingxenye zokuvikela kanye nohlelo lokuxhuma. Umzimba webhokisi wenziwe kakhulu ngepuleti lensimbi eligoqekile elibandayo noma insimbi engagqwali. Uhlobo lwangaphandle lunezinga lokuvikela le-NEMA 3R, elingavimbela imvula, uthuli nezinto zakwamanye amazwe ukuthi zingangeni. Isigaba somugqa engenayo sifakwe iswishi eyinhloko, ene-circuit breaker evamile yamandla aphezulu esebenza njengokulawula okuyinhloko ukufeza ukuvikelwa kokuvala isekethe kanye nokulayisha ngokweqile. Ngaphakathi, amandla kagesi asatshalaliswa ngamabhasi ethusi. Kufakwe izinkinobho eziningi zokuphuka kwegatsha, futhi igatsha ngalinye lifakwe i-circuit breaker ukuhlinzeka ngokuvikelwa kwe-short-circuit kanye nokulayisha ngokweqile kwemigqa yegatsha. Ibhokisi lifakwe imigoqo yensimbi engathathi hlangothi kanye nemigoqo yokumisa ukuqinisekisa ukuphepha kukagesi. Ngesikhathi esifanayo, isikhala sezintambo esifanelekile sigciniwe, futhi izintambo zihlelwe ngendlela ejwayelekile ukunciphisa ukuphazamiseka kanye nezingozi zamaphutha. Isakhiwo sonke sincane futhi ukuvikelwa kuthembekile. Akugcini nje ngokufeza ukukhishwa kwamandla kweziteshi eziningi kodwa futhi kusiza ukulungiswa okusheshayo, ukuqinisekisa ukunikezwa kwamandla okuqhubekayo nokuzinzile ezimweni ezahlukahlukene.
