Attaching insulated bus bar to metal box
Installing Midnite Solar short bus bars like these:
in aluminum breakers box - Big Baby Box from the same Midnite, like this:
One bus bar is shown on the photo, and there are mounting holes pre-drilled for it. There is enough room to install another bar - above or below the breakers.
The instruction for bus bar says "use sheet metal screws #10". There are holes in black/red insulators to put the crew, head-up, and pilot holes in the box wall. The box is 1/16" aluminum - ignore where it says "steel" on the diagram. It's aluminum, it says so on Midnite site, and magnet doesn't stick.
#10 sheet metal screw in 1/16" aluminum, really? Like it's going to hold. Being not an electrician, I'm puzzled. Ok, the shortest screw will still penetrate the wall that the box is installed on - 1/4" ply and whatever is underneath. So it will hold. So I'm mounting the "sandwich" of bus and box to the wall, and if I want to remove the box, I need to undo the bus bars. Then plywood wall will have 4 holes after bars, in addition to 4 holes after the box itself. Not that I plan to remove it soon.
Am I missing something here?
