real mess

Hello Folks, I have a lot of old gray two wire going mostly to fixtures and outlets. How do I tell the gauge??? Volt meter?? I would like to replace it where I can. Should I use a 12/2 to be safe??? The best I can follow it the gray wire seems to be connected to 15 amp breakers. Most of the newer white wire is 12/2. I've got 3 electric boxes and would love to rewire the whole place,albeit no cash though.

I'm converting a couple of rooms and want to use an old 12/2 that was running into a recessed heater in an old bathroom. With the proper rated recepts can I use this for outlets and switches. Best I can tell, it's looks like a dedicated run. Thanks in advance Eric

 

Please know that it's possible the former heater-circuit may have been 220 volts, so you may have to convert the circuit to 110 volts at the CB panel.

I suggest that you purchase an in-expensive needle-indicating type multi-meter designed to test 220 volts AC.Avoid the digital-type which appears "hi-tech" but will indicate "phantom voltages" in certain tests which results in bewilderment.

Good Luck & Enjoy the Experience!!!!!!!!!!!!

 

Hey Patt, I have the old heater and it says 120 volt on it. I will buy the meter anyway so I can check the old gray wires as well. Thanks Eric
