Running an extension cord underground...
Posted on 7/10/19 at 7:52 pm

Anyone ever done it with success.
I'm thinking of running 100 ft to my shed for lighting, bench grinder and other tools. Every thing I've read is no,no,no.
I would only have it plugged in when I am working. Yea or ney?

In a small pvc pipe you should be ok

If you were to run it in pipe it may last but if you’re just going to bury it in the ground it won’t.

Yes sir I would definitely do pvc. I would like to use 1/2" to protect the cord. Question is without splicing the pipe how can I feed the cord with the plugs? Other than detaching and re- attaching.

Cut one plug off, thread cord through pipe, re-attach plug

Get you some 12/2 direct burial Romex and you can just add an end on to it.

Thank you for the information.
12/2 sounds like the best option.

Why are you going to spend all the time to dog a hole to bury an extension cords when it probably isn’t much more to do it right?

Exactly. If I’m digging a trench I’m going to go ahead and run Romex it’s not that hard to do.
Well I’ve never done it before but I know of a methhead who got arrested for running a romex line from his neighbors shop to his house because his power got shut off.
Surely if he could pull that off it can’t be that hard

Before you connect your pipe, lay it out on the ground (next to the trench) and run your cord through one section at a time, then connect them.

Make sure you mark it somehow. I wouldn't want to have left the cord plugged in and then later on go to dig a hole for some tomato plants in the wrong spot.

I'm thinking of running 100 ft to my shed for lighting, bench grinder and other tools.
use 1" pvc electrical conduit (3/4" is too tight to feed the wire) and use the long sweeping 90s for it at the end to come up.
for the wire use 10-2 with ground would handle this fine with 30A breaker, but if it was me, i would do 8-2 with ground and 40A breaker just to be sure in case one day i wanted run something like a compressor that needs more power
just like with trailers, its always best to go bigger then you think you need.

Dont run any wire underground with a paper insulation inside of it.

Sounds more to me like he just wants to plug it in to an existing outlet, not run a box off the main.

No.
And dont put romex nm or uf in a pipe either.
Get some thhn and put that in a pipe.

Buy some conduit and or pvc and run it inside that
Posted on 7/11/19 at 9:27 am to AU1960
Don't even think of doing that even running it in PVC pipe.

given the situation where he has lights on using bench grinder and a compressor kicks on he could easily be tripping a 30A breaker
just because you have the extra capacity doesnt mean you always use it but if you max out what you have it can cause all sorts of issues
you have 200A to your house and yet you never use half that
