2. Electrical wiring in North America - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_North...

   This device, which can be a circuit breaker or the first outlet on a circuit, is designed to detect hazardous electrical arcing in the branch circuit wiring as well as in cords and plugs. An AFCI device is designed to trip quickly when it detects potentially dangerous arcing that could start a fire, but not trip with harmless arcing as part of ...

3. Electrical wiring - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring

   Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.

4. Wiring diagram - Wikipedia

   en.wikipedia.org/wiki/Wiring_diagram

   An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

5. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   This three-wire single-phase system is common in North America for residential and light commercial applications. Circuit breaker panels typically have two live (hot) wires, and a neutral, connected at one point to the grounded center tap of a local transformer. Usually, one of the live wires is black and the other one red; the neutral wire is ...

6. IEC 60309 - Wikipedia

   en.wikipedia.org/wiki/IEC_60309

   This allows one to choose single-phase AC power at either 110–120 volts between phase and neutral or 220–240 volts between phase and phase. Since these two modes do not need three phases there is also a dark yellow-orange four-pin connector available designed for a single-phase 110–120 or 220–240 volt load.

7. 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 ...

8. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   This saves a homeowner a trip to the breaker panel, should the device trip. Unlike AFCI breakers, AFCI receptacles can be used on any wiring system, regardless of the panel. [citation needed] When installed as the first receptacle on a branch circuit, AFCI receptacles can provide series arc protection for the entire branch circuit. They also ...

9. Electrical wiring in the United Kingdom - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_the...

   Residual-current device (RCD), also residual current circuit breaker (RCCB) A circuit breaker triggered by unequal currents in line and neutral wires (i.e., electrical power is passing to earth). Mandatory for most circuits as of 17th Edition regulations. Residual current circuit breaker with overcurrent protection (RCBO)
