2. Generator interlock kit - Wikipedia

   en.wikipedia.org/wiki/Generator_Interlock_Kit

   The kit achieves the same function by adding an external interlock onto an existing breaker panel that allows the main breaker to be turned on or one designated load breaker to be turned on, but not both at the same time. The interlocked load breaker is repurposed as the "backfeed" breaker, and a generator is connected to it (wired directly or ...

3. Recloser - Wikipedia

   en.wikipedia.org/wiki/Recloser

   Automatically closing the breaker after it has tripped and stayed open for a brief amount of time, usually after 1 to 5 seconds, is a standard procedure. [ 5 ] Reclosers are often used as a key component in a smart grid , as they are effectively computer controlled switchgear which can be remotely operated and interrogated using supervisory ...

4. Disconnector - Wikipedia

   en.wikipedia.org/wiki/Disconnector

   In a disconnecting circuit breaker the disconnectors are integrated in the breaking chamber, which eliminates the need for separate disconnectors. The intention of this combined device is to decrease maintenance and increase availability and reliability. The usage of this device instead of a disconnector is limited due to the fact that the open ...

   "Switched socket-outlets and connectors with or without interlock" applies to self-contained products that combine within a single enclosure, a socket-outlet or connector according to IEC 60309-1 or IEC 60309-2 and a switching device, with a rated operating voltage not exceeding 1000 VDC or VAC and 500 Hz, and a rated current not exceeding 800 A.

6. Industrial and multiphase power plugs and sockets - Wikipedia

   en.wikipedia.org/wiki/Industrial_and_multiphase...

   Industrial devices may also be constructed to be dust or water-tight. NEMA wiring devices are made in current ratings from 15–60 A, and voltage ratings from 125–600 V. There are two basic configurations of NEMA plug and socket: straight-blade and locking. Numbers prefixed by L are twist-lock, others are straight blade. Locking type ...

7. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   NEMA L10 series devices are two-pole plus neutral, three-wire, non-grounding devices for 125/250 volts single-phase. These are deprecated due to the lack of grounding but L10-20 and L10-30 devices are specified by NEMA and are commercially available.
