Thanks to all the great advice I've got a pretty good handle on my boathouse feeder installation. I've got my 2-2-2-4 AL buried in conduit and ready to go. Some of these recent threads about AL/CU compatibility has me wondering. Do most if not all of the residential grade sub panels like I would buy at HD/Lowes have lugs and/or main breakers compatible with AL? I guess I would have to be concerned about the Neutral and Ground bars too. I know to use the anti-ox goop (I used it on my original 200A house panel upgrade that ya'll helped me with last year), but I never considered the AL rating on panel and breaker lugs before. Lowes has an inexpensive Siemens panel combo right now on sale. 100A w/ 5 20A breakers, but I can't find any detailed info online about the CU/AL specs.
