Residential Garage Wiring NEC 2017

[bwaryjasz]

Are electric vehicle Charging stations now a requirement in new construction for residential? I thought I remember hearing it mentioned during code update but am having trouble finding anything in the code. I see that the receptacles required are 1 per garage bay and have to be on a 20A circuit. any help would be greatly appreciated.

EV not required.

EV not required.

But may be part of spec as a selling point "feature "

That requirement was in part because of expected increase in need for EV charging in the future. Still is no specific requirement for EV charging though.

I think it is way too soon to require anything more then 20 amp 120 volt circuits in dwelling garages, all other EV options are voluntary for the most part.

The only requirement I know about is if you install a circuit for an EV then it must be on a separate circuit

625.40 Electric Vehicle Branch Circuit. Each outlet installed
for the purpose of charging electric vehicles shall be supplied
by an individual branch circuit. Each circuit shall have no other
outlets.

The real impact, to me, of the changes for dwelling garages is that a 20 Amp receptacle outlet branch circuit has to be kept free of lighting and cannot serve other areas (with the exception of readily accessible outdoor receptacle outlets). That means two different branch circuits are in the garage, minimum. The other branch circuit is not limited to "garage only."

When I go to bid the wiring of a simple little detached garage with no service door (only the vehicle door), a garage that has a door opener, a single inside light and a wall receptacle, I have to supply this garage with a multiwire branch circuit at the minimum. Gone are the days of a single circuit garage.

Life is changing sometimes not for the better. I am not sure of the reason for these changing - I have heard it was because of EV's, however, I doubt that since one circuit for the receptacles in the garage would not do much for an EV charger. Imagine 2- 120V 20 amp chargers in a 2 car garage. It is not going to help a bit.

It is not going to help a bit.

Stay tuned. . . more changes are a'comin'

So in reading the new 2017 section 210.11(C)(4) ... the last sentence says "The circuit shall have no other outlets"

So the door opener would need to be on the lighting circuit?

The door opener would need to be on another circuit. And, there is an exception for readily accessible outdoor receptacle outlets allowed on the garage receptacle outlet circuit.

The rule describes a 20 Amp 120 Volt branch circuit installed for receptacle outlets in a garage, either attached or detatched, without any language to differentiate location or load served inside the garage. So, if the garage door opener is cord and plug connected at a receptacle outlet, that outlet may be connected to the 2017 NEC 210.11(C)(4) required branch circuit.

 

[shortcircuit2]

Can I connect a central vacuum outlet to this 210.11(C)(4) 20-amp branch circuit too?

 

[electricalist]

So for now the 20 amp outlet for the car charger is actually gonna be a service plug for the actual car charger.

Many cities here in the Bay Area are requiring either a level 2 charging outlet (50amp/4 wire) or a 3/4" conduit back to the panel from the garage for new or large remodel construction
