What he said...

12 AWG wire is intended for use with 20A breakers so you are good to
go.

14A\WG wire is for 15A breakers.

No, maybe. Depends on the length of the circuit and the expected load.

Yes, but you might want to think about a ground lead too, it might be

I think a ground wire is a given now. I think you'd be hard pressed to find
12/2 without a ground.

Do you _really_ think that if you walk into an electrical supply house and ask
for a length of 12/2 cable, you're _not_ going to get cable with black, white,
*and* ground?????

To the OP: ignore Jeff's post. If you're running a 120V 20A circuit, 12/2 is
what you want -- it has the ground included. Don't buy 12/3, thinking that you
need that to get the ground wire. You don't.

12/3 will actually have 4 wires: black, white, red, and bare.

Which, of course, is exactly why I told the OP not to be misled by Jeff's
wise-ass post into mistakenly thinking that he'd need 12/3 to have a ground
wire. Get with the program.

Doesn't 12/2 generally already have a ground lead?

Well, yes, but it's a stupid joke, because of course the ground lead *is*
there.

Well I for one, the quintessential pack rat, have got quite a bit of
unused 12/2 WITHOUT ground lying in my basement, right next to a coil of
Romex, so maybe the OP has some too.

Judging from some of the electrical inquiries We've all read here lately
it's not completely beyond belief that someone might be thinking about
using up some "old new stock" two wire Romex or even (G-d forbid) a
piece of an old extension cord to install a new outlet.

But, I do agree that it WAS a stupid joke on my part.

I was going to use it in two places:

1) new bathroom where the ceiling light is also a fan and heater +
the light over the sink + the GFI outlets around the perimeter of the
room

2) in a new bedroom I'm adding on that will have a baseboard electric
heater + ceiling light + perimeter outlets.

Can I stay with 12/2 and 20 amp breaker or should I go 10/2? Does this
change your responses? Thanks.

That depends on the ratings of the equipment you're adding, especially the
heaters -- and also on whether you're planning to put all that on one circuit,
or two (or more).

Post the electrical ratings of the heaters, including the voltage (baseboard
heaters are often 240V), and we can give you a better answer.

Calculate the maximum current when all the loads are on. If it's more than
20 A, then go to 10 gage wire.

Around here you cannot wire lights on a 20A circuit. Only dedicated
receptacle circuits.

And where does THAT rule come from? and where is "around here"

Rule 30-104(a) in the CEC. Lighting circuits in a dwelling unit must be
protected by 15A fuses or breakers.

I'm in Canada.

Chris

Your light-heat-vent unit will probably require a dedicated 20 amp circuit,
then the rest of the bathroom could be wired with an additional 20 amp
circuit. You should run a dedicated circuit for the bedroom electric heat,
and at least one 15 or 20 amp circuits for the balance of the room, keep in
mind in the U.S. all bedroom wiring is to be AFCI protected

True. What he actually said was, "I took the initiative in creating the
Internet." Which, of course, was a lie.

It was probably one of Rush Limbaugh's lies.

No, Gore was the liar there -- and in many other cases, too. Example: he
claimed that his mother sang him to sleep as a child using the song "Look for
the Union Label" as a lullaby -- but he was already a grown man when the song
was written. Another example: he claimed to have spent his youth working on
the family farm; truth is he spent a few weekends there.

Try pointing to just *one* lie told by Limbaugh.
