2. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A circuit breaker is an electrical safety device designed to protect an electrical circuit ... Two-pole common-trip breakers are common on 120/240-volt systems ...

3. Sulfur hexafluoride circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Sulfur_hexafluoride...

   Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other ...

4. Distribution board - Wikipedia

   en.wikipedia.org/wiki/Distribution_board

   The neutral wire is connected to the neutral busbar to the left with all the white wires, and the two hot wires are attached to the main breaker. Below the main breaker are the two bus bars carrying the current between the main breaker and the two columns of branch circuit breakers, with each respective circuit's red and black hot wires leading ...

5. Bimetallic strip - Wikipedia

   en.wikipedia.org/wiki/Bimetallic_strip

   The strip consists of two strips of different metals which expand at different rates as they are heated, usually steel and copper, or in some cases steel and brass. The strips are joined together throughout their length by riveting, brazing or welding. The different expansions force the flat strip to bend one way if heated, and in the opposite ...

6. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   Single-pole circuit breakers feed 120 V circuits from one of the 120 V buses within the panel, or two-pole circuit breakers feed 240-volt circuits from both buses. 120 V circuits are the most common, and used to power NEMA 1 and NEMA 5 outlets, and most residential and light commercial direct-wired lighting circuits.

7. Utilization categories - Wikipedia

   en.wikipedia.org/wiki/Utilization_categories

   The utilization categories category for low-voltage switchgear defines the characteristic operating conditions for switchgear such as contactors, circuit-breakers, circuit-breaker-fuse units, contactor relays, etc. These devices are dimensioned for different electrical loads and for different operating conditions.

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 ...
