Electrical Code for Room Air Conditioners
[ad#block]Question: The NEC states that the total rating of a plug-connected room air conditioner, where lighting units or other appliances are also supplied, shall not exceed what percent of the branch-circuit rating.
Background: Eddie is a Student from Sacramento, California.
Thanks for your electrical question Eddie.
Where the branch-circuit supplies lighting outlets and general use receptacles, the total rating of a plug-connected room air conditioner cannot exceed 50 percent of the branch-circuit rating. An example would be that an air conditioner with a full-load current of 10 amperes or less may be installed on a 20-ampere branch circuit that supplies other loads, and the receptacle that supplies power to the air conditioner should be rated for 20-amperes.
