Name the violations

The contractor that did this really screwed up the furnace installation.

This is on the outside of a house near an A/C condenser. The 50 amp breakers are the disconnect for the A/C and the 20 amp supplies the furnace. The over-current protection for the feeder is 60 amp.

The big wire is #8 --- the little wire is #12.

408.36(D) for back fed breaker. That panel will not accept a tie down I believe

Looks like they used the equipment grounding conductor as a neutral. oops... and they did not bond the bar to the box but I imagine Chris got that. I didn't check his articles.

1. Feeder needs min #6 AWG 3 wire.

2. Seperate neutral & grounding bus bar.

3. 8 AWG use 50A for HVAC OK.
