Does anybody know if GFCI breaker’s are required in So California, Los Angeles County area for EVSE in garages, thanks
625.54 Ground-Fault Circuit-Interrupter Protection for Personnel
In addition to the requirements in 210.8, all receptacles installed for the connection of electric vehicle charging shall have ground-fault circuit-interrupter protection for personnel.
Copy that, thank you. I haven’t seen the job yet but if I run emt the 8 awg thhn is 50 Amp, I should be able to use that provided my receptacle and breaker are 75 c, but NM B would require 6 AWG 334.80, otherwise USE or SE 6 awg is that correctIs is a hard wired outlet or a receptacle outlet?
Yeah I think your good there. I try to hardwire them if the customer lets me, then no GFCI breaker or needed.
Per post #2, if you are using a receptacle, then you will need to provide GFCI protection.That would be great if I could use a standard breaker, what about the receptacle brand,
I am using my phone as my internet has been down waiting on Frontier since Saturday, I only now realized I wasn’t seeing everything posted, my apologies to all. Ok from previous post it seems that without a doubt that with a receptacle I am going to have to buy a GFCI breaker and hardwired I won’t, definitely hardwired sounds like the far better option as this guy is getting quotes for $800-$900. I haven’t checked on the cost of a permit yet but will do that this morning, surrounding cities are expensive though , at least $200 for a circuit.Per post #2, if you are using a receptacle, then you will need to provide GFCI protection.

Excellent, thank you for that, I will definitely keep that in mind. So just to be clear, this is not a result of improper torquing or other misdeeds like a little of the insulation underneath the terminal screw, those Hubbles are around $100 and then about the same for the GFCI breakerYou need to know details about the EVSE. Not all are capable being hard-wired.
If installing a receptacle, a high-quality, industrial version is a must. You can find many examples of melted $10 Ideal receptacles on EV forums.

Right but the plug on the EVSE determines whether or not we use a neutral correct? Also if you hardwire then there would be no neutral either? Does some EVSE come with a neutral terminal for hardwiring? I just spoke to bldg/sfty $ 98 for the permit, no GFCI necessary if hardwired unless the manufacturers instructions call for itThe whole range receptacle NEMA 14-50 for a EVSE is bizarre to me.
No electric car takes 120/240 thru the EVSE, its just 240.
I have only ever seen one Level 2 EVSE that uses a neutral, and that was a commercial 'pay to use' unit at a public library building about 10 years ago.
Now even those are all 240V.
Agreed, but if I install a receptacle with a neutral terminal, I'm going to wire the neutral.The whole range receptacle NEMA 14-50 for a EVSE is bizarre to me.

No the EVSE manufacturers put a 4 wire range cord on there to be 'helpful'. Probably for compatibility with RV outlets.Right but the plug on the EVSE determines whether or not we use a neutral correct?
Correct, always check the nameplate to verify.Also if you hardwire then there would be no neutral either?
I gather the problem is that there's no such thing as standard NEMA receptacles with two lines and a ground but no neutral.
If it’s anywhere like Atlanta, the permit will be outrageous. I permitted a house at my previous company, City of Atlanta wanted a separate permit for the EV. That permit was more than the permit for the whole house! It’s all a money game.I am using my phone as my internet has been down waiting on Frontier since Saturday, I only now realized I wasn’t seeing everything posted, my apologies to all.
