Why does my outlet have 2 black and 2 white wires?

Since this one has more, it means it is part of a “series”. A “series” means there are 2 or more outlets powered by the same wiring and circuit. The other set of black and white wires goes to the next outlet down the line and that’s how it gets its power.

You Can Use Another Electrical Outlet When: (Don’t make matters worse by adding yet another outlet to the circuit.) Electrical codes restrict the number of lights or electrical outlets that can be connected to one circuit. Typically, you can have no more than eight lights or electrical outlets on a 15-amp circuit.

Can I wire lights and outlets on the same circuit?

My short answer to the question is that “Yes, lights and power outlets (a.k.a AC receptacles) can be on the same circuit controlled by a circuit breaker, especially in a single family residential house”. … The circuit branch controlled by the 15A circuit breaker has a couple of lights and AC outlets connected.

The electrician will check the color of the wires feeding to the outlet.
