An outlet for tapping into an electrical circuit usually with an appliance plug. Duplex wall receptacles are the most common type, but larger appliance receptacles are also found in household electrical systems.
Run the new cable from the source electrical box, through the notches and into the new outlet box. Pull an extra 8-10 inches of cable into each outlet box to allow for stripping and connecting the wires.
A junction box has several holes with removable plugs in the sides and back. Choose holes conveniently located for the cables you are splicing and remove the plugs. Have a cable clamp for each one and loosen the screws to open the collar. Pull about 8 to 10 inches of cable through the clamp and tighten the collar around it so it’s firmly held but not pinching the plastic.
A device for controlled interruption of current flow in a circuit. A single-pole, single-throw (SPST) light switch is the most common type found in household circuits. These have one set of contacts and can be either ON or OFF. A single-pole, double-throw (SPDT) switch has two sets of contacts and can alternate between them to divert current between two separate paths. A 3-way switch is an example of a SPDT household switch.
