Level 2 Charger Installed

wow, great job. that would take me 3-4 weeks, well done! sharp looking unit

what model is it?

 

Nice job!

 

Very nice! I wish I have the ability to DIY my wiring to install L2 EVSE.

Our garage is detached from our house where the main panel is located. Currently, there is 30" conduit running under the asphalt paved driveway to connect the circuit in the garage on 20A breaker. If I can replace the wire in the conduit without tearing the pavement, it may save substantial cost. What is the outer diameter of the 6/3 wire you used?

 

You should have no trouble pulling heavier gauge wire. That's a nice benefit of conduit. In our case, we have the 3/4" size. That has a 4-wire capacity with each being 6-gauge.

 

Thanks. That makes my L2 EVSE installation project much more economical. I am sure I can just use the existing wire which I believe 12-gauge as a fish line.

 

If it's a very long, pull, I like to use wire pulling lube (aka cow snot) to keep the friction heat down.

 

OK. It's ~30 feet long under the paved blacktop driveway between my house and the garage. Luckily, it is a straight line without any bend except the 90-degree angles at the bottom of the walls. I can pull either from the garage side or the house side. Previously, I thought the only way I can change the wire would be to dig a trench to remove the existing wire and laying a new, but that would be way too much work. I don't know what type of conduit is under the ground, but I think it is a PVC type since that is what is visible above the ground.

 

That looks just about ideal. And 30' isn't very far. I'd still use lube if it was me, just in case. And, if there's room to add wires later, I like to include a pull string in the wire bundle so you won't have to sacrifice one of the existing wires to add the new ones. But, if that's 3/4" conduit and you're putting in #6 wire, I imagine the conduit will be pretty full since the max number of #8 in 3/4 PVC is 4. The charts allow 3 #6 THHN in 3/4" non-metalic conduit.

 

That's a great tip from a pro. I just took this pic on the outside of the garage foundation where the conduit enters the building. The O.D. of the PVC is 1 1/4". I guess it is larger than 3/4" PVC?

 

It says 1" on the LB cover, so that's also the nominal size of the conduit. (It's probably marked somewhere, but may not be printed on the exposed areas.) According to the chart I checked, schedule 40 1" rigid PVC has an ID of 1.004". This should be a pretty easy job.
