Running Cable to Garage

I looked into the Polaris connectors. Amazon has them for not that much more that split bolts sometimes sell for, I think. Polaris connectors are the way I will go in the future.

It looks like Polaris connectors might use less box space than split bolts too.

Would maybe even a slightly smaller box than 12x12x6 be enough with the space saved by using the Polaris connectors??
Thanks for the insight on cutting the armor back. The wires will be inside the 2" pvc stand pipe, so they could run up into the transition box without the armor but would it be required that the armor be bonded at both ends?

Polaris connectors I think are underground approved

No it will not require bonding on both ends if you take the jacket of then it’s just 3 wires. The only reason that the NEC requires bonding is because of the armor the wires are in just strip the armor of and with using PVC conduit and PVC boxes there is nothing to bond to

That's excellent. Thanks Megawatt. So after the armor is stripped it's simply 3 conductors and a ground in PVC conduit. Thanks for sharing that info??

@tinkering you are quite welcome good luck and let me know how it’s going

We are going to run Teck90 or ACWU cable underground from house to garage. There will be just a 60A breaker in the house and garage for now but want to lay a large enough cable to carry 100A in the future. We have approximately 60 ft of ACWU #3/0 aluminum to make the run. It is about 2" in diameter, the 3/0 conductors are close to 1/2" so it's over sized which will make it a little more work to install.
Some answers to my questions might make it easier.

• With the cable being just under 2" diameter what diameter does the PVC conduit have to be up to the LB fitting? Is 2 1/2" good enough? 4" seems like overkill.
• We need to run the 3/0 into a transition box, then come out of the box with #3AWG because the 3/0 won't fit the panel.

If I can't tame this configuration down a bit, maybe we'll just buy some ACWU with #3AWG copper.

You will need 2 inch PVC conduit and yes you can splice with # 3 and I’m telling you to over size your LB because it a b—— to pull wire through that, maybe 21/2 or 3 inch
