They would also have a junction box on the ceiling for a light and fan.įor example, a master bedroom could have 7 outlets, and then a light fixture at the ceiling for a fan. Most new construction bedrooms have an outlet every 6 feet, or on every wall. This ensuring your circuit does not supply more than 80% of the total 15 amp circuit.Īll electrical appliances like TVs, chargers, and lightbulbs should state their wattage on the packaging so you can just add up the expected wattage from each appliance to get your total wattage for the circuit. So, if you are using a 15 amp circuit and you are using regular 120-volt outlets, then the max watts you can use is 1440 watts. outlets run on 120 volts (unless it is a special appliance connection like a dryer). To find out how many amps you need or how many you will use, use this formula: 80%*(Amps) = Watts/Volts. While this would be an extreme case, read further to find out how many amps you may use on a circuit. So, if you have a 15 amp circuit with 20 outlets, you should be fine as long as you are not running more than 12 amps through the circuit at one time. This is so the circuit breaker does not constantly trip during regular use. The NEC only states that a circuit cannot supply more than 80% of the circuit breakers limits. The National Electrical Code (NEC) does not limit the number of outlets per circuit. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. The 20s are better receptacles, they are more expensive though but aside from that it’s just more built in safety factor.Technically, you can have as many outlets on a 15 amp circuit breaker as you want. With respect to the laws of physics and the NEC, it isn’t necessary but you gotta so whatever you gotta do you pass inspection. ![]() If it’s against the CEC, than fine, use 20 amp plugs. Not sure where you are located, but in the United States, it is absolutely acceptable to use 15 amp receptacles on a 20 amp circuit.Įdit: just realized your in Canada. And again in Massachusetts we have the craziest licensing guidelines, permitting requirements and construction laws that exist in the United States. Every job I’ve done has passed inspection. I’ve never been on a residential job and seen 20 amp plugs used unless it’s a dedicated receptacle. Unlike most US states, a Journeyman’s license obtained here can be used anywhere in the US, point being that we have the most strict laws in the country regarding licensure. And theoretically I could hook two 9 amp devices into a 15 amp receptacle and melt it before the 20 amp breaker opened. Ultimately the breaker is intended to protect the wiring and the receptacle. So I feel confident in saying you should not have a 15 amp receptacle attached to a 20 amp circuit. ![]() ![]() But the CEC typically lags the NEC as far as updates etc. Obviously I cannot speak for the NEC ised in America, or specific rules that can be enforced in certain states or provinces. There are specific allowances for things like your stove where you may have a 40 amp receptacle on a 50 amp breaker, probably because of the cyclical nature of the loads and unlikely hood of it operating at 100% load. But the CEC, which is based primarily on the NEC states in rule 14-600 - Receptacles shall not be connected to a branch circuit having an overcurrent protection rated or set at more than the ampere rating of the receptacle, except as permitted by other sections of the code.
