Depending on where you're located, you may be able to get your electric utility to pay for most or all of the work to get the necessary amount of power to the location you're installing the chargers.

Where do the electric utilities pay for such work? MA?

Yes, we have multiple utilities here in MA, and each of their programs differ. The state kicks in some cash as well in some cases. RI has similar programs.

I put in a 50 foot trench to have my 240V, 50 A line run from my house to my garage. Line will be installed next week. Putting in a 22 inch deep trench is painful, even with a gas trencher/ditch witch. I'll need to clean it up prior to the line install next week. Anyone who is planning on doing this and hasn't done it before, I'm happy to share my experience, as I made all kinds of mistakes that I'd prefer others avoid. Getting closer...

I'd be interested in hearing your "tips". I'd make sure you used 1" conduit and at least 6 AWG wire. Electricians probably have more accurate suggestions. Luckily my run from panel to garage was less than 15 feet.

3/4" conduit would work as well. Since you only need three 6 AWG wires in the pipe and the conduit is rated for 4 wires. Conduit Fill Table - Electrical References - Elliott Electric Supply

My Tesla charger has 3/4" conduit and the new Juicebox we used 1", both work great. We were able to pull the wires pretty easy in both conduits with a fair amount of bends. We used a couple junction boxes to make it easier. The runs were around 50 ft each.

I thought the NEMA 14-50 needed 4 wires but I'm no expert at this.

My JuiceBox and Tesla wall charger both use 2 hots and one ground. You are correct that NEMA 14-50 needs 4 wires (2 hots, 1 ground, 1 neutral). Either way though a 3/4” conduit will safely fit four 6 AWG wires.

I'm leaving all that to my electricians. Putting in the 22 in deep trench is the real pain! Rent a trencher and don't dig it yourself. Your back will thank you!

Thanks...only reason I mentioned NEMA 14-50 is that Audi says their charger uses that spec. Didn't want someone to run 3 wires when they might need 4 wires.
