Electrical grounding question

[marksmopars]

Just another note, electric code says no more than 360 degrees of bends between junction boxes, 6 nineties won’t pull nicely, max of 4. If it’s plastic (pvc) pipe you will have a good chance of breaking it, the rope will burn through the corners or the wire will break trying.

Yeah that's why I cut into the wall of the garage to bypass two of them and I'm trying to dig down near the barn to bypass two as well. Once I get the wires fed through the long straight portion, I can then easily feed them through the rest of the 90s.

If you can get the pipe empty then get a string and tie a ball of yarn (like the ball on top of a stocking cap) to it. You should be able to suck it through with a vacuum. Good luck

I was able to successfully pull my wire through last weekend.

Had to cut a hole in my garage and install a small pull box. Also cut the conduit outside my barn and installed one as well. This way there were only two 90* elbows from pull box to pull box.

I was able to pull the wires back and forth somewhat freely once I had each of the ends disconnected and pulled through the pull boxes. The run had three 6awg wires so I pulled two of them out, reused one for ground and then used the one left in there as my pull wire to pull my new conductors through. Attached three 4awg wires and one 6awg wire to the left over wire and pulled them through fairly easily for the most part.

Only thing that sucked is my 500ft roll of 4awg came up about 10ft short of my new sub panel in the garage that my solar powers. I wound up having to buy 10ft of 4/3 romex wire at $9.50 per ft. Stupid expensive. Spliced that in a junction box to the wires I pulled through and I'm good to go now.

Now when I run 6awg from my barn to my new shop, everything will be up to code as far as the amperage that the wires can carry goes and I'll have a real ground that won't allow my entire metal shop to become energized if a short occurs.

Nice work!

They're still in but I have six 90s total in the run. I cut into the conduit to bypass two of the 90s at my house and I'd need to cut into it to bypass the two or three 90s at the barn to even have a chance of pulling anything through there. Even a new pull string.

The code says no more than 4 - 90s in a single run conduit

We call them mouses it a sponge you tie pull sting on hook made into the sponge and blow it thur the other end with air
