I am currently doing a bathroom remodel, it has a existing 20amp circuit in it. I also pulled a 20a homerun up form the panel. I installed a singlelamp heat fan vent draws 2.5amps. The inspector is telling me this need to be on its own circuit. I allready 2, 20amp circuits in the bath 1 being a home run. Is he right ? What say you? regards jim :roll:

Re: Bath rm requirements
The only required circuit to a bathroom is a 20A circuit to feed all receptacle outlets. All other outlets including lighting, exhaust fans, and etc. can be served from any general lighting circuit.

Re: Bath rm requirements
If the 20 amp circuit serves only one bathroom then it is allowed to supply all outlets in just that bathroom. But if you want to supply other receptacle outlets in another bathroom then it can only supply the receptacle outlets and other outlets have to be on another circuit which can be any GP circuit. If this heat/vent fan unit does not use more that 50% of a circuit rating it is allowed to be fed from any GP circuit or the dedacated 20 amp bath circuit (as long as this circuit does not supply another bathroom.

Re: Bath rm requirements
if that 1 new home run is 12-2 it can feed anything and everything in that one bathroom and any general lighting circuit can pick up any thing else in that bathroom except the receptacles.
Keep in mind that 12-2 HR can not leave that bathroom for anything else no matter how small the load.
I have seen some stupid cases where maybe all you want to add is an outside light to a pool bath but you can't even add that 60 watt load.
Then again out of doing the right job on huge bathrooms i have run as many as 3 circuits that never left the bathroom

Re: Bath rm requirements
Make sure you read the instructions for the Heat Light/Fan. All the units that I have installed specify that they must be on a 15 amp circuit. I?m not sure why since fan only units don?t have this requirement.

Re: Bath rm requirements
Thanks for the replies, It was my understanding that the 20amp homerun could serve anything in the bathroom and met all the code requirements as long as it did not leave the room. I have since talked to the inspector and he said as long as i have two circuits in the bathroom i am fine so he signed me off. i still don't no why? Is'nt a 20amp homerun all i need to meet the 2002 requirements?

Don't have a code book in front of me but isn't it required that the bathroom, or any habitable room for that matter, requires at least one switched lighting circuit? Perhaps this is the 2nd circuit referenced.The only required circuit to a bathroom is a 20A circuit to feed all receptacle outlets.

Re: Bath rm requirements
You can take care of the entire bathroom on 1 20 amp 12-2 circuit.Now if for some reason the fan is marked 15 amp only then your in a bind and would need to comply.Keep in mind this 1 circuit is only practicle for normal bath rooms.I have some that almost use up that 20 amp on lights.And if it has a jacuzi tub add 1 more 20 amp dedicated circuit.There is the need to keep the customer happy even if you meet code.If the lights take more than a few hundred watts i would think about more than just that 1 circuit

Close but this is not the intent or the words in the NEC:210.70(A)(1)Don't have a code book in front of me but isn't it required that the bathroom, or any habitable room for that matter, requires at least one switched lighting circuit?
This has nothing to do with required circuits as there is no requirement for this lighting to be on it's own circuit.(1) Habitable Rooms. At least one wall switch-controlled lighting outlet shall be installed in every habitable room and bathroom.

Re: Bath rm requirements
'the load served' ... if the load(s) are larger than the one 20 amp circuit, then you will need to add another circuit(s). If the manufacturer requires a circuit for the unit, then I would dare say that two circuits would be required in that bathroom.
