  2. Generator interlock kit - Wikipedia

    en.wikipedia.org/wiki/Generator_Interlock_Kit

    Early generator interlock kits consisted of two sliding steel or plastic (depending on the brand) plates held together by three bolts and installed on the front cover of the home's breaker panel, however, some models made by Eaton (formerly Cutler-Hammer) and Siemens for panels manufactured by them install on the adjacent circuit breakers themselves and consist of a sliding arm for breakers ...

    The key can then be used to unlock the kiln door. While the key is removed from the switch interlock, a plunger from the interlock mechanically prevents the power switch from being turned on. Power cannot be re-applied to the kiln until the kiln door is locked, releasing the key, and the key is then returned to the power switch interlock. [5]

  4. Circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Circuit_breaker

    Power circuit breakers and medium- and high-voltage circuit breakers used for industrial or electric power systems are designed and tested to ANSI or IEEE standards in the C37 series. For example, standard C37.16 lists preferred frame size current ratings for power circuit breakers in the range of 600 to 5000 amperes.

  5. Camlock (electrical) - Wikipedia

    en.wikipedia.org/wiki/Camlock_(electrical)

    Another version is the Posi-Lok, which features keyed, shrouded connectors, and panels with sequencing interlocks. [3] Camlock is generally used where temporary connections of 3-phase and/or more than 50 A are needed. Applications include connecting large temporary generators or load banks to distribution panels or building disconnects. Common ...

  6. Interlock (engineering) - Wikipedia

    en.wikipedia.org/wiki/Interlock_(engineering)

    An interlock device is designed to allow a generator to provide backup power in such a way that it (a) prevents main and generator power to be connected at the same time, and (b) allows circuit breakers to operate normally without interference in the event of an overload condition. Most interlock devices for electrical systems employ a ...

  7. Distribution board - Wikipedia

    en.wikipedia.org/wiki/Distribution_board

    A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

  8. Isolated-phase bus - Wikipedia

    en.wikipedia.org/wiki/Isolated-phase_bus

    The conductors between the generator and the first circuit breaker are even more important to protect against two- and three-phase faults because there is no breaker that can stop the fault current from the generator. While most modern circuit breakers will interrupt the fault current in less than 50 ms, the fault current from the generator ...

  9. Disconnector - Wikipedia

    en.wikipedia.org/wiki/Disconnector

    In high-voltage or complex systems, these locks may be part of a trapped-key interlock system to ensure proper sequence of operation. In some designs, the disconnector has the additional ability to earth the isolated circuit thereby providing additional safety. Such an arrangement would apply to circuits that inter-connect power distribution ...
