Romex 6/2 NM-B Wire and Conduit


Rjniles is right about how cheap aluminum(AL) is. And AngelArs is right to follow the instructions. Personally, I couldn't find the copper restriction in either instruction manual. However, AL would be a whole lot of extra work. You'd have to research the listing(label) on the terminations and the equipment to see if it's allowed and for torque specs. You'd have to use listed for AL wire connectors (not wire nuts). And use Noalox and a torque screwdriver. If that's fun for you let me know.

Regarding the fire seal, I've seen several videos showing that the caulk burns very easily. Since it can ignite so easily, what is the point of buying and using it?

Are you saying that you have seen videos showing the 3M fire sealant FB136 burning easily ?
Fire sealant is not a caulk, except in a very generic usage of the word.

Not just the 3M brand but other brands as well. In fact there is only one brand that I've seen that does not catch on fire. How can these other brands be a fire seal if they easily catch on fire?

Was the caulk dry or fresh out of the tube when it was burning?

True fire caulk will expand due to fire. Maybe that is what you saw and interpreted it as being on fire.

Nope. There are many examples on line but here are two quick ones. I guess a picture (or video in this case) is worth a thousand words.

Example One

Example Two

That is firestop expanding foam, not fire caulk. I don't know anything about the foams, never used them.
