Description
English: Single-phase fuse box with overlimited circuit breakers.
  • Look: this fuse box has one C32 breaker, three C25 breakers and one C16 breaker - logically, this room using one powerful water pump, three stoves and one 16A socket. Main breaker is 50A; following this logic, demand factor in this room is 0.41 =) Main breaker is 2-pole in single-phase system despite there is no reason to disconnect neutral wire. And of couse see RCD - if somewhere is leakage, all room will stay in darkness.
Русский: Однофазный квартирный щит с завышеными номиналами предохранителей.
  • Согласно монтажу: один 32-амперный автомат, три 25-амперных автомата и один 16-амперный автомат - то есть логически помещение использует один мощный насос, три электроплиты и одну 16-амперную розетку. Главный автомат С50, т.е. коэффициент спроса только 0,41; ВА 2-полюсный в однофазной системе несмотря на отсутствие причин в отключении нулевого провода. Используется общее на все линии УЗО, т.е. в случае одной небольшой утечки на землю, вся квартира останется без энергоснабжения.
