Hi there, I just wanted to know if anyone knows which rooms(in a residence) with Windows require the dedicated AC circuit? Does it include barhrooms, kitchens, basements? Thank in advance?
 
If you're in NYC you need them as outlined here in the NYC Electrical Code, note they're not required if you have central AC.

Welcome to the Forum. :)

ARTICLE 210
Branch Circuits
SECTION 210.11
Subsection 210.11(C)(4) – Add a new subsection 210.11(C)(4) to read as follows:
(4) Air-Conditioning Branch Circuit. In addition to the number of branch circuits required by other
parts of this section, an individual branch circuit shall be provided for each air-conditioning receptacle
required by 210.52(I).

SECTION 210.52
Subsection 210.52(E)(3) – Delete the Exception in its entirety.
Subsection 210.52(I) – Add a new subsection 210.52(I) to read as follows:
(I) Outlet Requirements For Residential-Type Occupancies. In addition to the requirements set forth
in subsections (A) through (H) of this section, living rooms, bedrooms, dining rooms or similar rooms
shall have at least one receptacle outlet installed for air conditioners. Such outlets shall be supplied by an
individual branch circuit.
Exception: Buildings with central air conditioning systems that serve any of the above areas shall not
require separate outlets in those areas.

That can come into play if you do have the AC unit. I think OP is asking about requirement to have dedicated AC outlets even if not known if there will be an AC in a particular window, there is no such rule in NEC regarding that.

Sounds like NYC has local codes for such situation anyway though.
 
I think I know what he's talking about. Window ac's typically have a label that say "individual branch circuit required" or something along those lines. This is just a manufacturers boiler plate. I put no stock in it. Are we going to start running dedicated circuits for an 5 amp unit in a small bedroom? :happyno::roll:

If he's in NYC then yes.
 
Thank you infinity for the warm welcome! And thank you all for contributing your two cents. My question is about NYC as I currently live in that crazy place. However I was wondering specifically whether this requirement applies to bathrooms and kitchens. Is it included in that which you quoted: " In addition to the requirements set forth
in subsections (A) through (H) of this section, living rooms, bedrooms, dining rooms or similar rooms
shall have at least one receptacle outlet installed for air conditioners. Such outlets shall be supplied by an
individual branch circuit."

Awaiting your response.

No not required in those locations. The eight subsections (A)-(H) are the standard requirements in the NEC (in this case 2008). The NYC amendment adds a ninth subsection which is (I) and that adds the AC receptacle requirement for the rooms listed: "living rooms, bedrooms, dining rooms or similar rooms" which excludes kitchens and bathrooms.

I believe the ban is on #14 wire, not 15a breakers.

That is correct. Up until about 20 years ago you could use only 15 amp circuits for general purpose receptacle circuits and all lighting circuits that were less than 250 volts to ground with the minimum #12 conductors.
