I got a Septic pump control box and I ran the system with a multi wire circuit 12 thhn/thwn. I realized that tapping off the RV pedestal feeders the lugs are not rated at 90% Here my original question about that.
calculating-additional-load-on-feeder-for-rv-pedestals.2574311

So instead of doing the Polaris taps on the meter , Or pulling out the 12 and pulling in 10 thhn/thwn pipe. does 240.g apply to the feeder to the control box circuit breakers. I think It applies I see nothing that says I can't do that.

Are you saying that the #12 AWG conductors at 75° C are too small for your application?

Not if I can’t size them 75% table. I know the limitation up to 10awg but this should fall into the 240.g allowance.
Just want to make sure for inspector. Lately he is not liking pushing thing to the code minimum.
