Hello Folks, I took a 120 volt, 750 watt in wall heater out. It was connected to 12/2 wire. I used a volt meter and the best I can tell I'm getting a 125 reading. (possible??). I tried to follow it back to the breaker but keep getting lost. I'm going to test the breakers 1 by 1 when the wife comes home. The below question is based on it being a 20 amp breaker.

I want to add 4 outlets and a light switch with 2 closet covered cans. Can I use 15 amp recepts and switches or do I need 20 amp???? I will run 12/2 on the add on. Thanks in advance for your help.Eric

 

Hello Folks, It is on a 20 amp breaker!!!! I'm not sure if it's dedicated though. Thanks Eric

 

15-amp receptacles and switches are perfectly fine.

 

15 Amp recepts. are perfectly code compliant on a 20 Amp circuit, as long as there is more than one on the circuit. As you have four recepts, you're install will be just fine.

Incidentally 125 V is highly possible. Most power companies hold a +/- 5% tolerance on incoming power. So, your 120 service could be anywhere between 114 and 126 volts and still be erfectly fine. This will also have no negative effect on what you plug into the recept, as most common electrical items are built to withstand a +/- 10% power range, some more so. Unless you plan on hooking up sensitive medical equipment, or Japanese built machine tools, you have nothing to worry about

 

Just one duplex receptacle counts as "more than one". So since hardly anybody installs simplex receptacles, it's pretty hard to mess this up.

 

Thanks for info folks, John, what no chuckle today!!!! Eric
