Electricital question

Do you mean 4 discrete conductors (a cable 1s an assembly of conductors in an outer sheath)

If this is type USE it should be good for 90 amps. The question is what neutral current you will have since the neutral is smaller. If your big loads are 240v it doesn't matter that much.

Steve-

Take a look at

I'm thinking that someone goofed by spec'ing a small neutral but if the loads are mostly 240v it might not be a problem.

In aluminum 2-2-2-6 is good for 90 amps with 75C insulation 4-4-4-6 is good for 65 amps with 75C insulation

You've got what appears to be 2-2-4-6. If the loads per leg are balanced (ie max imbalance is < 65 amps) then your good for 90 amps. If the loads are imbalanced you'd be limited to 65 amps.

This is probably a situation that will work but isn't quite kosher.

Something tells that this is not allowed by code..... perhaps one of our code experts will chime in.

Are there any letters on the #2 wire insulation that look like TW, THHN, RHH, XHHW? If the wire is in free air, it will carry a lot more current. Depending on the insulation, the amp rating could be as high as 150 amps.
