Powering the new Building

[NotOrganized]

New building is almost finished. Time to run power. When we bought the land, we put a mobile home for temporary housing while we planned our eventual home. We still have the power panel that was set next to it. This panel is fed from 450ft away with 4/0 4/0 4/0 with a local ground rod. I have service run to a close by building via 4 cables of #1 copper. It shares the local ground with this panel. My new building is about 100 feet away. I am considering my options.

Wire the new building from the existing panel, or scrap this eyesore of a yard ornament and just extend the service line to the new building and feed the old building from there. I never wired the old building so moving the service to it is no issue.

If I extend the line I will still need an above ground junction box or can I do a subterranean?


What would you do?

Looks like u have a challenger panel.

Those are garbage so I would replace it.

200a on 4/0 al over 450' + 100' additional feet is gonna have a voltage drop issue.

Any chance that a new run straight to the pole would be shorter?

Unfortunately a new run would be a straight shot past the existing pictured panel. I don't really need 200 amp in the building. Mainly for lights, a lift and garage doors and possibly 50amp for an RV. No big draw that a 100amp panel would not handle.

My other option would be to extend the line 30' to the old building and feed the new building from it.

Ok so maybe i misunderstood.

Does the new building have a separate service/meter via the #1 cu u described?

Or is it being fed from the 200a panel pictured?

BTW each building requires grounding electrodes and under current code, 2 are required...

The old building is fed via the challenger panel. I ran 4 wires of #1 and it's actually 60ft. I just went out and put a killawatt in an outlet by the panel. Showed 121v. I fired up a large air compressor that is rated at 32amps on a 50amp circuit. Voltage dropped momentarily to 117 and held at 119. Its been there 20 years and never flinched.

I was told for 100 amp service from the challenger I could run 2-2-2 urd and put a ground rod by the new panel.

The panel is a C-H/Eaton BR, other then the main no difference from Challenger, so it is a trash panel.

It might be low quality but it has stood the test of time and still works. I'll ask my electrician his opinion. I know he is very picky about panels.

The two don't go together, if someone is picky about panels they don't choose the bottom of the line and the Bryant/Westinghouse/Cutler-Hammer & now Eaton BR line is bottom of the line, something had to replace Zinsco after they were discontinued as the worst .

He was not the one that chose it. I can't remember who did but it was not him. I am sure he will have a strong opinion when he see's it. I am not opposed to replacing it. I would rather remove it altogether if I could.
