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.

Yeah, you'll be fine. I can't recall ever seeing a panel, breaker, ground/neutral bar rated for copper only.

AL is fine to terminate in most any panel. The lugs in the panel are usually AL themselves. Some higher end panels will have copper buss bars and lugs.
When using the Noalox, rub it into the strands of the conductor and put a dab in the terminal lug, so the inspector can see it.

Got a call from our neighbor up there. Rained 6" and our entire ditch is washed out from the house down to the level portion of the run. Crapola!! Any suggestions on what to fill the ditch with to help erosion? Bricks or Rocks?

Just more dirt. You have to pack that stuff in layers. Add dirt and tamp it down, and add more dirt. Add dirt and tamp until it is full and tight.
