[Oeva-list] Question about planning for charging station.

[Dick Burnham]

I am not an electrician and suggest you hire one.  At the very least run this by the permit desk at the jurisdiction you live in and get a permit.  With that disclaimer - you will probably be better off running a single pipe with 220 power to the garage and land it in a new sub panel.  Inside the sub panel you can pull a 110 circuit with it's own breaker and land that on how ever many outlets you want or can run on that circuit.  In the future if you want to add a 220 outlet for your spanking new EV then it is easy to add breakers and pull a 220 circuit out of your panel without running any new pipe or a bunch of wire to the garage.  The other benefit is that if you in your garage and pop the breaker it is right there to reset and you don't have to run into the house.

Good luck!

Dick

Subject: [Oeva-list] Question about planning for charging station.

Hi,

I'm digging a ditch to replace a faulty underground power connection to my detached garage. I was just going to lay in one PVC pipe for the 120V 15A
3 wires, but somebody suggested that I plan for an EV charging station.
I'm thinking of laying in two pipes, a 3/4" with the 120V 3 wire 12GA THHN and another 3/4 inch that would be able to carry up to 3 THHN wires @ 6 GA in the future, (I'd just put in a pull cord). I presume that I will not be getting 3 Phase 480 to my house in the country. So right now I have 240 200Amp service to the house.

I looked up some of the codes for EV charging stations at the Beaverton Library a few weeks ago but I didn't study enough.

I'm thinking that there is probably more to this planning, so before I bury the pipes I'd like to know that I've got my bases covered.

Thanks,
Gene Fifield
