You are watching: How many outlets can be on a 20 amp breaker
The general standard is to wire lights top top 15-amp circuits and outlets on 20-amp circuits. However, the is feasible to cable a light right into a 20-amp circuit and also be in ~ code.If you decide to go this route, the does not adjust the circuit’s number of outlets. Each light the you include in the wiring would take the ar of one outlet.Thus, if you want to incorporate two irradiate fittings in the circuit, friend would have the limit to install eight electric outlets for a maximum of ten outlets.To summarize, the sum of outlets and lights ~ above the circuit need to not exceed ten, the maximum number of outlets permitted on the circuit.
What have the right to Run on a 20-Amp Circuit?
The intention of 20-amp circuits is no for to run heavy-duty family members items such together cooktops, stoves or high volume refrigerators or washing machines, and also dryers.20-amp circuits are an ideal for to run smaller family appliances. The NEC needs at the very least two 20-amp circuits mounted in a kitchen for the countertop. This regulation caters come medium-duty kitchen appliances offered at the countertop level without overloading the outlets.The adhering to devices and also appliances can connect to 20-amp circuit outlets.Microwave ovens.Blenders.Toasters.Mixers.Home entertain systems.Television.Freestanding lamps.Vacuum cleaners.Even though the number of outlets ~ above a 20-amp circuit have the right to be the ideal number, that is feasible to overload the circuit at the outlet point. Many human being plug too plenty of devices right into the outlets with extender plugs.
It is an essential to ensure that the complete Watts on the mechanism does no exceed the circuit wattage. You have the right to calculate the best wattage that deserve to run ~ above a 20-amp circuit v the following equation.Max amps * volts = watts16 amps * 120 volts = 1920 wattsThe number of 1920-Watts represents the preferably wattage that deserve to run ~ above the circuit. using this number together the top limit, we can tally up the watts of all the devices associated to the outlets. You can uncover the watts that each an equipment uses published on the company plate for each device.
Tally up the watt for each an equipment connected to the circuit. This full should be less than the total number of Watts allowed on the circuit, which, in the instance of a 20-amp circuit, is 1920-Watts.
ConclusionThe maximum number of electrical outlets you have the right to run top top a 20-amp circuit is ten. Ten outlets will power devices and appliances without exceeding the 80% capacity dominion for residential electric wiring.If girlfriend need added outlets, the ideal solution would be to install a second 20-amp circuit and also divide the number of outlets equally throughout the two circuits.Overloading a circuit is a attention practice, therefore if you are unsure of her wiring or calculations, operation them by a default electrician because that confirmation.
