some great exceptions in the code but with the given example we might be pushing the limits on a single circuit if this is a shared (female) bathroom. IOW, do load calcs based on real loading of (possible) multiple hair driers, curling irons, etc. Basically, we have a $20k renovation that really needs $100 - $200 more for another circuit to be safe in the long run. That's chump change in the big picture!
Informative. Did I miss something? I was anticipating an answer to running bathroom light(s) from the dedicated 20 AMP bathroom receptacle which is GFCI. While I appreciate the towel bar example, referencing that in the context of NEC exceptions strayed too far off topic for me. In short, with a dedicated 20 AMP power source to a single bathroom GFCI outlet, can a vanity light w/ switch be powered from the GFCI receptacle?
I do not recommend running the bathroom lights off the 20 amp receptacle circuit for two reasons. First off, 12Awg wire is more tedious to work with than 14awg. Second, GFCI protection. Depending on the wiring configuration, a tripped GFCI = lights out, not exactly a fun experience when that happens while you're taking a shower. If you decide to wire the lights off the bath receptacle circuit, use a standard 20 amp breaker (unless local codes require AFCI protection for the bathroom), a GFCI receptacle and be sure to wire the lighting circuit on the LINE side of the receptacle. Note, an exhaust fan or fan/light/heater installed over a tub or shower must be listed for damp locations, or wet locations if subject to direct spray, and might be required by the manufacturer to have GFCI protection.
What about the reverse? Let's say I have a bathroom with a 20a circuit for receptacles and a 15a circuit for lighting. I want to add an additional receptacle in a spot that would be diifficult for running off an existing receptacle but super easy to run from an existing light. Is this allowed by code if I use a 15a GFCI for the new receptacle?
I’ve done this before due to circumstances of a remodel but if you have more than one bathroom it will cost you another gfci breaker or receptacle because if you choose to put lights and receptacles on the same circuit in a bathroom it must remain dedicated to that bathroom and cannot jump to another bathroom, according to my ahj. Is this true and if so where’s the exception in the code?
Electricians should know not to run all the electric in a room off of a single breaker. In each room, one outlet should (perhaps must) be run on a different breaker, in the event the other circuit breaker trips. Practically speaking, ceiling lights should always be run on a separate breaker. This creates some difficulties, but so what.

Good information. Thank you for sharing your knowledge.
Wonderful graphics. Any mention of GFCI on this circuit?
straight to the point, best part is summary at the end. thanks.
Glad you found it helpful!
Thanks, always informative.
Like always. Well done.
National Exception Code😂
Great info! Thanks!!
Happy New Year , Coach !!!!!

Very goo info , thanks
I have a question for the show; what are some tips for a new journeyman on leading/training apprentices on the job for the first time?

Pretty much never run lighting with outlets on the circuit anymore.
Amazing video thank you
You're welcome! I'm glad you enjoy the content.
can i run all the bathrooms with one breaker
nothing better than a hairdryer/curler/other device going bad and knocking the bathroom lights out with it. in the dark fumbling around.

@@awpr8r But the question was if he can tap off a 15A lighting circuit to provide a 15A GFCI recept.

210.11(C)(3)
It sure can but then you cant leave the bathroom with the circuit to jump another bath gfci
It’s just lazy (cheep ) sharing lights / receptacle
Just run it separate instead of making it complex
Yes but wouldn’t
The bathroom circuit shall not serve any other load outside of the bathroom
You lost me at the end when you said You couldnt run receptacles
