2. Surge protector - Wikipedia

   en.wikipedia.org/wiki/Surge_protector

   Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS)) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...

3. Transient recovery voltage - Wikipedia

   en.wikipedia.org/wiki/Transient_Recovery_Voltage

   A terminal fault is a fault that occurs at the circuit breaker terminals. The circuit breaker interrupts a short-circuit at current zero, at this instant the supply voltage is maximum and the recovery voltage tends to reach the supply voltage with a high frequency transient. The normalized value of the overshoot or amplitude factor is 1.4.

6. Zinsco - Wikipedia

   en.wikipedia.org/wiki/Zinsco

   Zinsco would remain with copper in both their panels and breakers until the third major copper shortage in the early 1960s, when they would switch to an aluminum bus. In 1963, Zinsco introduced the R-38 twin breaker, which was the only twin circuit breaker that also made contact on both bus-bars for 240 volts in a single breaker space.

7. Substation - Wikipedia

   en.wikipedia.org/wiki/Substation

   The arrangement of switches, circuit breakers, and buses used affects the cost and reliability of the substation. For important substations a ring bus, double bus, or so-called "breaker and a half" setup can be used, so that the failure of any one circuit breaker does not interrupt power to other circuits, and so that parts of the substation ...
