Installing and Connecting a 220 Volt Heater Circuit to a Sub Panel
220 Volt Heater Circuit Installed to Sub Panel
I'm having a problem with wiring a 220 volt heater circuit.
I installed a 20 amp double pole breaker in my panel, and I ran 12/2 wire with a ground to the outlet. On the breaker, I connected the white and black wires to each pole, and connected the bare copper wire to ground.
At the outlet, I connected the bare copper wire to ground (the green terminal), and I connected the white wire to one side, and the black wire to the other.
When testing with a volt meter, if I put one terminal on ground and one terminal on either pole, I get 110 volts.
If I put both terminals on the poles, I get nothing. Aren't I supposed to be getting 220? The bottom line is that the 220 volt heater that I bought isn't working when I plug it in. The heater is single phase, so I didn't think it mattered which side I connected the black and white wires to. Regardless, the heater still doesn't work if I reverse them. At first, I thought the heater might be defective, so I exchanged it for another one, but the new one doesn't work either. Obviously, there's something wrong with the way I wired the outlet. Can you help? |
If you look at that 20 amp double pole breaker on the right, that's what I'm wiring my outlet to. If I touch the volt meter leads to each pole of the breaker, I get nothing. One lead to a pole and one lead to ground, I get 110 on each pole. From: Patrick D. Ok, I killed the power to this sub panel before I started messing around in it. When I bought this double pole breaker to do this little project, I noticed that it only had one metal clip at the bottom, but the whole box of breakers where I bought it were like this, so I didn't think much of it. Is this normal? I've attached a picture of the panel with the breaker out as well as a picture of the back of the breaker. |

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical TesterThis is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet TesterThis is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring. It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire CutterMy absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.. The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use. |
