general information/ definitions
feeder circuit
the circuit conductors between the service equipment, the source of a separately derived system, or other power source and the final branch-circuit overcurrent device.
afci
designed to recognize dangerous arcs in your wiring and immediately break the flow of electricity, thus preventing your electrical system from becoming an ignition source for a fire.
double pole switch
has two connections to 2 separate circuits. They are essentially 2 switches in one.

parallel circuit
one that has two or more paths for the electricity to flow, the loads are parallel to each other.
tamper resistant outlet
a standard receptacle but adds a built-in safety mechanism that helps prevent electricity from energizing anything that is stuck into the receptacle that shouldn't be.
3 way switch
larger than a single pole switch and has three screw terminals for wiring connections, plus a ground.

equipment for general use
in a device, an electrical circuit of lower resistance than that of a normal circuit, typically resulting from the unintended contact of components and consequent accidental diversion of the current.
triplex outlet
three sockets that can be mounted in a single box, does not require separate interconnecting wiring and can be covered by a single wall plate.
dimmer switch
a device for varying the brightness of an electric light.
