Am I hearing things?

#10 is used for 30amp breakers and the receptacles for those are 240 not your standard 120 and are made to accomodate #10 wire. Some components are 240 so in that case they would run 10/2 or 10/3. 

I called the electrician and he said it was a 25 amp breaker. He assured me I'm fine. Mike

He probably put the 25 amp breaker on your AC unit which is not unusual that's about the only thing 25 breakers are used for AC units or water heaters.

Call him back and ask him to cite the section in the NEC code that said he can use a 25 amp breaker where a 5-20R (20 amp) duplex receptacle is installed on a branch circuit.


Have him look at NEC
110.3 (B)

210.21 (B) (3).
Where connected to a branch circuit supplying two or more receptacles or outlets, receptacle ratings shall conform to the values listed in Table 210.21 (B) (3), ......


Table 210.21(B)(3)
Circuit rating (Amperes) ............Receptacle rating (Amperes)
20 amp ............................................... 15 or 20 amp
30 amp .................................................. 30 amp

If you have had problems with nuisance tripping with a 20 amp breaker I would suggest the electrician check and see if the Electrical Panel manufacturer makes an HM (High Magnetic) circuit breaker. An HM breaker has a longer lag time for inrush current.

In an earlier post I asked you a few questions. The questions asked relates to the problems you are experiencing with the sound from your audio system, when connected to the new dedicated circuit.

I will get a polarity tester and I don't kniw tbe particulars. But I do know when I saw the wire it was orange 10 ga and there was no ground wire in it. So how could he ground it otherwise? I'm just going to get another electrician verify everything and quote this post. Thanks Mike
