2. Zinsco - Wikipedia

   en.wikipedia.org/wiki/Zinsco

   But, from 1982 until 1994, the 200-amp service panels used a Zinsco frame main breaker. Challenger flourished through the 80s, and was eventually received by Westinghouse in a multi-asset deal, in order for Westinghouse to sell its remaining electrical manufacturing facilities to Eaton Corporation in 1994.

3. Disconnector - Wikipedia

   en.wikipedia.org/wiki/Disconnector

   In electrical engineering, a disconnector, disconnect switch or isolator switch is a type of switching device with visible contacts, used to ensure that an electrical circuit is completely de-energized for service or maintenance.

4. NEMA enclosure types - Wikipedia

   Certified and labelled for use in areas with specific hazardous conditions: for indoor and outdoor use in locations classified as Class II, Groups E, F, or G as defined in NFPA standards such as the NEC. 10: MSHA. Meets the requirements of the Mine Safety and Health Administration, 30 CFR Part 18 (1978). 11: General-purpose.

5. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   The other end of the three secondary windings and the neutral are brought down the service drop to the service panel. 230 V loads are connected between any of the three-phase wires and the neutral. Because the phases are 120 degrees from each other, the voltage between any two phases is sqrt(3) * 230V = 400V, compared to the 2 * 120V = 240V in ...

6. Motor control center - Wikipedia

   en.wikipedia.org/wiki/Motor_control_center

   Motor control centers are usually used for low voltage three-phase alternating current motors from 208 V to 600 V. Medium-voltage motor control centers are made for large motors running at 2300 V to around 15000 V, using vacuum contactors for switching and with separate compartments for power switching and control.

7. Pad-mounted transformer - Wikipedia

   en.wikipedia.org/wiki/Pad-mounted_transformer

   Padmount transformers are used with underground electric power distribution lines at service drops to step down the primary voltage on the line to the lower secondary voltage supplied to utility customers. A single transformer may serve one large building or many homes.

9. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
