  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 ...

  3. Transfer switch - Wikipedia

    en.wikipedia.org/wiki/Transfer_switch

    When utility power returns for a minimum time, the transfer switch will transfer the house back to utility power and command the generator to turn off, after another specified amount of "cool down" time with no load on the generator. A transfer switch can be set up to provide power only to critical circuits or to entire electrical (sub)panels.

  4. Isolated-phase bus - Wikipedia

    en.wikipedia.org/wiki/Isolated-phase_bus

    In electrical engineering, isolated-phase bus (IPB), also known as phase-isolated bus (PIB) in some countries, is a method of construction for circuits carrying very large currents, typically between a generator and its step-up transformer in a steam or large hydroelectric power plant. Isolated phase bus during installation at the Bui Dam Ghana ...

  5. Synchronization (alternating current) - Wikipedia

    en.wikipedia.org/wiki/Synchronization...

    During installation of a generator, careful checks are made to ensure the generator terminals and all control wiring is correct so that the order of phases (phase sequence) matches the system. Connecting a generator with the wrong phase sequence will result in large, possibly damaging, currents as the system voltages are opposite to those of ...

  6. Busbar - Wikipedia

    en.wikipedia.org/wiki/Busbar

    In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks. They are generally ...

  7. Electrical bonding - Wikipedia

    en.wikipedia.org/wiki/Electrical_bonding

    Electrical bonding is the practice of intentionally electrically connecting all exposed metal items not designed to carry electricity in a room or building as protection from electric shock. Bonding is also used to minimize electrical arcing between metal surfaces with electrical potential differences.

  9. Live-line working - Wikipedia

    en.wikipedia.org/wiki/Live-line_working

    This is because the line might become inadvertently charged (e.g. through a back-charged transformer, possibly as a result of an improperly connected, inadequately isolated emergency generator at a customer facility), or inductively coupled from an adjacent in-service line. To prevent this, the line is first grounded via a clamp known as a bond ...
