When switched to LINE all circuits work. When switched to GEN, only circuits BDF work. ACE goes dead. I tested ACE with a volt meter and a clamp multimeter. Circuit A, for example draws 3A when on LINE. Switching to GEN drops it to 0.1- 0.2A.

BDF work great. Example, the 20A circuit it's drawing 11A from the generator during a test to run an air-conditioner. The other two 15A circuits draw 1.5 and 3A.

Generator is a 7000W Westinghouse.

I've double checked the wiring, and it is correct. The switch is new, and with the storm coming tomorrow, I'd love to have these other circuits running. I'm afraid I have a bad switch.enter image description here

I'm tempted to uninstall it and take it apart to test with a multi meter, but, I'd rather not.

Update: it looks like the bottom set of blades run the circuits in question. They are connected to a black wire on the side.

I was trying to see on the box looking for a lose connection, but, unfortunately, it's riveted, so access is limited at best.

Generator can generate either 120 or 240.

    Is the generator supplying both legs? – ThreePhaseEel Sep 11 '17 at 1:42
  • Yes. It supplies both sides (or should). – DrDamnit Sep 11 '17 at 1:51
  • Added a picture so show the inside. – DrDamnit Sep 11 '17 at 1:56
  • ACE are on the same pole. BDF are on the same pole. The generator is not supplying pole ACE correctly. (Or it's broken in the switch). Try switching poles as close to the switch as possible and see if the problem moves. – Harper - Reinstate Monica Sep 11 '17 at 2:09
  • If generator is not supplying poles correctly, could that be a miswired outlet? I installed the outlet too, but have not checked that. I think human error on my part is more likely than being switch. (Also, going that is the real problem). I have to go outside to check that, will report back. – DrDamnit Sep 11 '17 at 2:13
