You are watching: How many outlets can you put on a 20 amp breaker
The general standard is to wire lights on 15-amp circuits and outlets on 20-amp circuits. However, it is possible to wire a light into a 20-amp circuit and be within code.If you decide to go this route, it does not change the circuit’s number of outlets. Each light that you include in the wiring would take the place of one outlet.Thus, if you wanted to include two light fittings in the circuit, you would have the scope to install eight electrical outlets for a maximum of ten outlets.To summarize, the sum of outlets and lights on the circuit must not exceed ten, the maximum number of outlets allowed on the circuit.
What Can Run On a 20-Amp Circuit?
The intention of 20-amp circuits is not for running heavy-duty household items such as cooktops, stoves or high capacity refrigerators or washing machines, and dryers.20-amp circuits are suitable for running smaller household appliances. The NEC requires at least two 20-amp circuits installed in a kitchen for the countertop. This regulation caters to medium-duty kitchen appliances used at the countertop level without overloading the outlets.The following devices and appliances can connect to 20-amp circuit outlets.Microwave ovens.Blenders.Toasters.Mixers.Home entertainment systems.Television.Freestanding lamps.Vacuum cleaners.Even though the number of outlets on a 20-amp circuit can be the appropriate number, it is possible to overload the circuit at the outlet point. Many people plug too many devices into the outlets with extender plugs.
It is crucial to ensure that the total Watts on the system does not exceed the circuit wattage. You can calculate the maximum wattage that can run on a 20-amp circuit with the following equation.Max amps * volts = watts16 amps * 120 volts = 1920 wattsThe figure of 1920-Watts represents the maximum wattage that can run on the circuit. Using this number as the upper limit, we can tally up the Watts of all the devices connected to the outlets. You can find the Watts that each device uses printed on the service plate for each device.Tally up the Watts for each device connected to the circuit. This total should be less than the total number of Watts allowed on the circuit, which, in the case of a 20-amp circuit, is 1920-Watts.
ConclusionThe maximum number of electrical outlets you can run on a 20-amp circuit is ten. Ten outlets will power devices and appliances without exceeding the 80% capacity rule for residential electrical wiring.
If you need additional outlets, the best solution would be to install a second 20-amp circuit and divide the number of outlets equally across the two circuits.Overloading a circuit is a dangerous practice, so if you are unsure of your wiring or calculations, run them by a qualified electrician for confirmation.
