[Oeva-list] Question about planning for charging station

[Theoldcars at aol.com]

Hello Gene
 
That is a great idea since you are going to have a ditch open. I highly 
recommend using 1 1/2 inch and that might even be a little tight for three 
number six wires if you have a couple of corners. I did a straight run for 240 
in PVC with 1 inch that was 20 feet long. I used three number 6 wires and 
could hardly get them though. Inch and a half is not that more expensive and it 
would be much easier to pull wire. I was doing a straight run with no bends 
and almost had to use 1 1/2. If it would have had just one 90 degree elbow 
there is no way it would have worked.

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
