In My Opinion, you might find it here: :wink:rsheer said:Where would I find the definition if IMO?
roughly 1 foot of wire per square foot of floor space, give or take a few hundred feet.rsheer said:I am trying to do take offs on 4 different houses and I am looking for a simple but accurate way to estimate romex. Does anyone have a easy simple formula that works?

or maybe it's more like .75 feet of wire per 1 square foot of space.
Well I'm not quite sure, but I know that 12/3 isn't necessary and I've never used it in a house or found a good reason to.celtic said:How does this ROT translate into feet of:
14/2 (general lighting/recept)
14/3 (smokes and 3-ways)
12/2 (small app; bath)
12/3 (MWBC for SA ?)
10/3 (Condensor)
?
not necessary yes but more cost effective for SABCsteelersman said:Well I'm not quite sure, but I know that 12/3 isn't necessary and I've never used it in a house or found a good reason to.
what type of box or what location would you split the circuit? 1-12/3 and 2-12/2's? It just seems like more work IMO.Rewire said:not necessary yes but more cost effective for SABC
You just use the 3 wire and alternate devices (all GFI type).steelersman said:what type of box or what location would you split the circuit? 1-12/3 and 2-12/2's? It just seems like more work IMO.

interesting. So you just use the 3 wire throughout the 2 SA circuits and use and alternate red one first for example then black on the next and red on the next and black on the next and so on? Your still spending more money on wire and 20 cubic inch boxes throughout. But it's a new idea to me so I can appreciate that. I remember I learned the hard way that you can't share a neutral for 2 circuits if 1 of them needs to be gfi protected when I pulled 14/3 homerun to sump pump outlet and 14/2 out of that to the basement/outdoor recepts. gfi circuit.celtic said:You just use the 3 wire and alternate devices (all GFI type).
Saves on material (2 less copper conductors, etc)
Saves on time (1 less run to pull, etc)
I think a Carlon B122A is big enough.

that seems like alot of wire for such a small space. I just can't imagine it taking a full roll.....oh well.Mule said:Thats interesting....The other day, had a guy that just wanted us to do a partial rough in....probably so he could see how to do it???...but any way....we wired a mst bed rm...closet...mst bath...all was probably about 300sq/ft..smaller house..and we used a full box 250ft and didnt have any left for HR's. It included min code, PLUS 6 cans, HVL...bla bla

Are you sure it will be more money?steelersman said:Your still spending more money on wire and 20 cubic inch boxes throughout.
