Summary

Description
Deutsch: Unterverteilung mit unsachgemäßer Verwendung der in der Verwendung strikt reservierten grün-gelben Leiter.
English: Improper wiring way in fuse box.
  • 1) 3-phase wiring should be protected by 3-poles circuit breakers. If 3rd phase shorts on PE, circuit breaker will switch off only 3rd phase; but other 2 phases still feed electric device. If electric device requires only symmetry feeding, it will destroy electric device.
  • 2) To be evident and quickly understandable for other electricians, each pole should have it's color:
    • Phase A should be wired by brown wire
    • Phase B should be wired by black wire
    • Phase C should be wired by grey wire
    • Zero should be wired by blue wire
    • PE should be wired by green-yellow wire
  • 3) RCD is missimg, but it is required for all installations in safety purposes.
Polski: szafa elektryczna
Русский: Неправильный способ установки электрощита.
  • 1) Все 3 фазы должны быть защищены 3-полюсным автоматом. В показанном на иллюстрации способе при замыкании фазы С на проводник с нулевым потенциалом, отключится только фаза С, остальные 2 продолжат питать потребитель. В случае, если электроустановка требует симметричное питание, данное подключение выведет её из строя.
  • 2) Для наглядности и простоты, каждый полюс должен иметь свой определённый цвет:
    • Фаза А - коричневый
    • Фаза В - чёрный
    • Фаза С - серый
    • Рабочий ноль - синий
    • Заземление - жёлто-зелёный
  • 3) Отсутствует УЗО для обеспечения большей безопасности.
