Breaker keeps tripping

[fbelec]

using a 14 gauge wire with a 20 amp breaker in residential is against code. that motor might draw 250 watts that wouldn't even blow a 5 amp breaker and all breakers will take a huge startup draw which this motor does not have 15 amp breakers will take a 50 amp startup current. most likely the fan unit. if there is a neutral wire touching ground that will trip the breaker also. if it is a square d homeline breaker don't be surprised if the breaker is junk. homeline has lots of problems.
get back to us with the answer. but i have noticed that this thread is starting to be a pissing contest

You have a problem. Whether it's the blower, breaker, wiring, or very unlikely, tv. You should get the electrician back to find it. Simply using a bigger breaker on a circuit that should NOT trip the breaker you are serving it with now isn't the solution.

"240.4(D) says unless specifically permitted in 240.4(E) or 240.4(G) the overcurrent protection shall not exceed 15 amps for 14 AWG."

That is correct. The ampacity for 14ga may be higher, if run in free air between poles, but not in walls and certainly not if this is a large house and the wire run is long. Code is pretty clear on this.

The thread is off track and has headed into DIY territory. Closing up.
