In the U.S., household current is delivered on three wires, a neutral wire and two hot wires. The voltage between either hot wire and the neutral wire is somewhere around 110 to 120 volts, RMS (root mean square). The voltage between the two hot wires is around 220 to 240 volts, RMS.
Q. What controls the flow of electricity in a circuit?
Switches are like gates that control the flow of electricity in a circuit. When a switch is open, it creates a gap in the circuit and current will not flow. When it is closed, it completes the circuit, and current flows through it.

Q. How many amps are in a household current?
In most homes, lighting and small appliance circuits are 15 or 20 amps, and major appliances are on 20, 50 or even 60 amp circuits. Second, the volts flowing through the wires. Volts are a measure of the pressure that causes current to flow through a circuit. Generally, household wiring is 120 or 240 volts.
Q. Is it OK to use a 20 amp outlet on a 15 amp circuit?
Electrical plugs designated as 20-amp will not fit into 15-amp outlets. A 15-amp circuit is usually served by 14-gauge wire and is protected by a 15-amp circuit breaker or fuse. A 20-amp circuit, protected by a 20-amp breaker or fuse, must be served by 12-gauge or 10-gauge wire.
Q. Can you use 14-gauge wire on a 20 amp breaker?
You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. Just use the side terminals.
Q. How far can you run 12 gauge electrical wire?
60 feet
Q. How many duplex outlets can I put on a 20 amp circuit?
10 duplex receptacles
Q. How many outlets and lights can I put on a 20 amp circuit?
10 outlets
Q. How many duplex outlets can I put on a 15 amp circuit?
Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.
Q. How many LED lights can I put on a 15 amp circuit?
Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.
Q. How many outlets can you put on a 20 amp circuit?
10 receptacles
