Question:

Re: CQD answer published Wednesday, December 21, 2016 -Garage Outlets

Hello, In your answer to the Code Question of the Day that was published on Tuesday, December 20, 2016, you stated that it is permissible to install garage door openers on the same circuit as the garage receptacles.  I respectfully disagree because the garage receptacles shall be in addition to those that are required for the garage door openers per Sec. 210.52(G).

Truly, Joseph A. Kraft

Answer:

Hey Joseph thanks for your comment. Your are correct that the receptacle(s) must be in addition to the receptacle(s) installed for specific equipment as stated in 210.52(G) but it doesn't prohibit those receptacles from being supplied from the same branch circuit.

A change to the 2017 NEC in 210.52(G) requires at least one receptacle outlet to be installed in each vehicle bay and it cannot be more than 5 1/2 ft above the floor. Also new to the 2017 NEC is 210.11(C)(4) which requires at least one 20 ampere branch circuit be installed to supply receptacle outlets in garages. Other outlets (such as lighting) are not allowed as stated in the last sentence of that new subdivision.
