Current code allows the use of 1 dedicated 20 amp branch circuit for one entire bathroom or the use of one dedicated 20 amp branch circuit for receptacles only in more than one bathroom.

That would be a minimum. Does not prohibit additional circuits regardless of the code the house is under. Additional circuits would not have to meet restriction of "bath only".

Hank,

I know I seem to acting like a PIA on this thread but that is not my intent, in any way.

While the current code states that a min. of one dedicated 20 circuit is required for an entire single bathroom (inclusive of the receptacles) or a single dedicated 20 amp circuit for receptacle use only in more than one bathroom is all that is required.

I read that to mean that if I want to add more branch circuits that's fine as long as they are dedicated branch-circuits and they are 20 amp.

Am I being semi-brain dead on this or splitting hairs to finely?

If your wife told you that you had to have $20 in your wallet when you left the house, and that you could only use that $20 for gas. That wouldn't mean that you couldn't have another $15 for a hamburger. And you wouldn't have to spend that $15 in one place. You could stop and buy her flowers on the way home from the burger joint.

You have met the requirement of having $20 for gas.

This thread makes me wonder what ever happened to TKRussel?

Well, I'm not sure that my Lady would allow that much currency in my wallet at any one time. My Lady is Scottish / Italian, she hails from a suburb of NYC (New Rochelle) and she was a U.S. Marine. I don't even try to pick a fight. I'm just an NYC kid from the Bronx that wisely chose the U.S. Navy. :)

I'm not saying that there can't be a 15 amp line for run into the bathroom for other purposes than a receptacle outlet.

I'm saying that if a circuit is run to a bathroom to supply a receptacle outlet, it is required to 20 amp. It cannot sit on the end of a 15 amp extended branch circuit. The focus I'm using is on the receptacle outlet, not a circuit that may supply lighting or other general use devices.

Why would you say that. Present and recent codes require a 20 amp circuit to a bath, serving only that bath or another bath. That does not prevent a second circuit from also serving that bath.
Just think of that second circuit as being a general lighting circuit.

While we don't know what code this structure comes under, the fact that the distribution panel uses fuses rather than breakers, is a good indication that the code probably predates the requirement that there be a dedicated circuit to the bath. I know of no requirement that all circuits to a bath be dedicated or that they must be 20 amp.

A general lighting circuit does not mean light fixtures only.

Harold,

I cannot about code editions prior to the 2008 edition. I do have a copy of the 2005 edition but that is all the way across my office and I'm just to lazy right now.

The code a minimum of 1 20 amp branch circuit to serve a bathroom, inclusive of a GFCI receptacle outlet. Yes, there can be more than one circuit. However, if there is only the one 20 amp circuit, it is not permissible to serve any other bathroom.

If there is a dedicated 20 amp circuit for the exclusive use of the receptacle outlet then you have the option to extend that circuit to another bathroom for the exclusive use of a receptacle outlet. It cannot serve any other loads but receptacles.

Are we saying the same thing?

I think the codes a little different up here in Canada. What I've found for code there's no mention about needing a separate 20 amp circuit in a bathroom just a gfci. Could be wrong though.

Well, I am basing my responses on the 2011 edition of the NEC. Chapter 2, citations 210.11(C)(3) and 210.52(D).

What does the Canadian code say in these two sections. To the best of my knowledge both Canada and the U.S. are very close in their code.
