Sub-panel

[XJHEAD]

Service Entrance cable, from Main Panel to 125 Amp sub-panel 4-wire 100' run inside, what gauge copper??

[OrangeCrush 86]

Probably 2 Gauge. I don't have my NEC on me though. 1 gauge would probably be better.

[XJHEAD]

1 is what I thought too, been a long time

[OrangeCrush 86]

I think 90 degree C 2 gauge is good for 130 amps, but like I said I don't have my NEC and it has been a while. I think you may need to do some other calculations for conductors feeding a panel. Good luck.

or
1-1-1-3 bare

[XJHEAD]

Go #1awg

Now I need to find it ?????

[TRDon]

You can technically go #2 but at that lengh, and the cost difference, I would go #1 unless you are looking at a pretty light loading schedule fo rthat panel.

Bill, let me know if you need cable. I can check with our vendors.

I cannot find any 1-1-1-3 in Fargo I guess I'll go with 2/0-2/0-2/0-1/0 AL.

You think 100' will roll up and fit in a suit-case.. I don't....

Make sure that the breakers you are terminating in is allowed the terminations of al wire. It should be but just double check before proceeding.
