Bath Wiring Question

raleighthings

Remodeling our townhouse and am fixing bathroom wiring. Currently the upstairs baths have lights, fans, outlets all on the same breaker that also controls other outlets in the house.

So I plan to put the outlets for both baths on one 20A breaker which I understand meets code.

Plus I'll move the lights and fans to a separate breaker. But can this breaker be shared with other lights in the house. Bedroom lights in this case.

The bedroom lighting can power the bath fans and lights if the circuit has reserve capacity.

If it were me I would run a circuit for each bathrooms receptacle.

If the basics didn't fill the panel, so would I.

Yes, but it will most likely have to be an AFCI breaker since it’s a bedroom. Different areas of the country have different requirements for Arc-fault breakers. Here in Michigan, we are on the 2008 code, and though the ’08 code requires AFCI’s nearly everywhere in a house, our state only requires bedrooms to have AFCI protection. Best to check with your local jurisdiction.

Sigh. AFCI requires a new panel. I wonder if I can get the wiring permitted without AFCIs then hire an electrician to do the panel. It's old and only basic replacement breakers are available.

On a side note, how do AFCIs work with things like TIVOs. A TIVO box does not have an on off switch. Just a power cord as it has to be running 24/7 to operate correctly. Do you have to put a power strip in between the TIVO and outlet with AFCI breakers just to keep from tripping the breaker when the TIVO is plugged in?
