Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit.
Can I use electrical tape to connect wires?
Wire Connectors Are the Best If you ever find wires joined with electrical tape, or the wires are twisted together and then wrapped with electrical tape, get rid of the tape and join the wires with wire nuts.
