Well House Load Center??

[bdhsfz6]

When I bought an adjacent piece of property and tore down a derelict house, I moved the meter to a power pedestal, rather than pulling it out completely. That way, I can run electric services to the well and out buildings without having separate meters installed.

When I constructed the power pedestal. the inspector required two 8' ground rods with #4 copper wire.

When I tore down the house, I pulled out 160' of 3/0 3 conductor copper service entrance cable from a conduit thinking I could reuse it. The inspector said it would be against code to do this?? Does that sound right? It's in good condition and about 25 years old. The insulation is perfect and you can still see the lubricant that was used to pull it in.

It weighs just under 350# and I can only get around $425 for it at the scrap yard. That much new wire would cost over $3K. I haven't used it yet and am thinking of selling it. Won't be much of a market though if it's against the code to use.

I think that grounds have to be bare wire.

They do around here. The #4 I used was bare wire.
I was also talking about service entrance cable and slightly off topic.

Sorry. I misunderstood what you wanted to use the wire for.

Our service drop, as well as our weatherhead wiring all needed to be replaced after fifty or so years of service. The power company insisted on replacing half the service drop (half way to the pole) one year and then two years later, when the corrosion was showing through the cracks in the insulation, the other half. Talk about pennywise and pound foolish.

Code, or not, I wouldn't reuse it. Insulation does age and start to fall apart. Something that I was forcibly reminded of recently here when I opened the electrical box feeding my welder outlet and discovered the insulation cracking off of the 4ga wire. Heavy gauge wire shorting isn't something that you want to be around.

I file replacing the wires under life safety/fire protection.

All the best, Peter

The NEC no longer permits separate grounding of subpanels. You have to run a ground wire all the way from the main service panel. I'm not sure I agree with that, because a local ground is a great safety measure, but that's the code. It does eliminate ground loops.

Interesting that would make less work.

The new sub panel in my shop was wired with 3/0 ACWU. Looking at a cut scrap, the ground wire is bare aluminum and about 1/2 the size of the other three conductors.

I'd agree with you on the NEC and grounding, but that's probably a sit around the stove and chat all winter item.

I'm not an NEC expert, but always happy to learn. Is that rule for sub panels in the same building? I.e. a well pump panel would be a different building, and therefore need a ground? (What is the section, or sections, that apply for that?)

All the best,
