Question:
Hey Charlie,
Is the amount receptacles on one 20 amp breaker the same for both commercial and residential?
Thanks Paul Ferguson
A
Answer:
Hey Paul thanks for your question. No, for dwellings, guest rooms and guest suites the receptacle load is included in the general lighting load so there is no limit of the number of receptacles on a branch circuit as covered in 220.14(J). Because many receptacle outlets have maximum spacing's in dwellings the receptacle load is more related to the amount of space and typical usage in those types of occupancies. For other occupancies based on 220.14(I) we use 180 VA for up to 3 receptacles on a yoke so for a 20 ampere branch circuit that would be 13.
