Romex 6/2 NM-B Wire and Conduit
 
I need to run some Romex® 6/2 NM-B wire (around 40 feet) from my garage to my basement. One of the walls it's going through is masonry. Does code require I use conduit? If not, is there any harm in running it through conduit? Thanks :)

Conduit not required but you can sleeve it thru the masonry.

What will you use the 6/2 for?

I am in the process of planning a generator/transfer box install. I know that 6/2 is overkill but one day I may want to upgrade to a bigger generator and don't want to have to rewire. I want to do the wiring once and do it right :)

Unless you are planning on a 120 volt generator with not plans to ever upgrade to 240, I would run 6/3

You're going to need 6-3 with ground. 6-2 is for 120V generators. 6-3 is for 240V ones. Are you using a transfer switch? Or an interlock kit?

I'm sorry, after reviewing you are correct, I'll be running 6/3. Thanks for catching that before I ordered the wire. The inlet box will be a Reliance PR50. Pretty sure the transfer box will be the Reliance Q510C because a Generac transfer box would require a subpanel. So far the generator will be the Generac XG7000E.

Garage to basement will need to fire block sealed.

Really? Didn't need to do this when I ran the wire for my compressor. What is the best way to fire block seal?

Fire block caulk

Lots of other brands also.

Any building supply, electrical supply or home center carries it

OK THANKS! :thumbsup:

I was planning on caulking anyway so I'll just use that kind. I will be using Fire Block insulation also.

You might want to look at Aluminum SER 4-4-4-6 cable. Will be cheaper than 6/3 NM copper

AngelArs 10-19-2012 04:12 PM

Reliance PR50 instructions specifically state to use only solid copper wire.

6-3 Romex will not come in solid.

Solid as in solid bare copper strands.

That's not what "solid" means with respect to wire. "Solid" means one single cylinder of metal per conductor. More than one is "stranded". #6 solid copper does exist (even #4 solid exists), but it's really unpleasant to work with, and you won't find cable that size with solid conductors.
