baseboard heater problem

I connected a baseboard heater (Rated 220) but cannot seem to get it working using a 220 connection. If I connect it as a 110 connection it works but I don't get the desired output. I checked the side by side breakers that are needed for the 220 connection and they both work. I am doing something wrong but cannot figure it out. Any suggestions?

Your details are too sketchy to offer much, but I'll try.

Did you run a brand new circuit or try to use something existing? If you ran a new circuit with a new breaker, what kind of breaker did you use? If you used a tandem breaker (two skinny breakers in a 1" wide package), then this cannot provide 240-volts except in some GE panels.

That's just a few random thoughts. Please provide more details of your project.

baseboard problem

The electrical panel is a Stablok panel which I was told should permit this type of connection. I ran a new circuit and tried to duplicate an existing 220 connection. To further complicate this problem, I took the existing working 220 connected breaker and moved it one position down in the panel so that I could have the space for the new circuit and it too did no longer work on 220 but works on 110.

You do not have the breaker in the correct position for 240. It needs to connect to both halves of the incoming service to provide 240. Where you have it connected you are providing the same half od the incoming service, and you don't have 240 from that.

The other possibility is that you miswired the connections somewhere.

The breaker has two wires(black and red) connected to it and a white to a common bar in the panel plus the ground?

Did you measure the voltage between the red and black wires?

How did you connect the wires at the heater? The white wire is superflous and should be capped at the thermostat and/or the heater.

When you moved the existing breaker down one position, was that a full position, or a half position?

baseboard problem

The breaker is single pole. That is why two adjacent breakers are required. These two breakers are tied together with a tie bar so they act as one. The wire used is a two wire (one black and one white) with a separate groung. There is no neutral third wire. The electrical code here permits this type of connection. The location of the breaker in the panel may be the problem as stated above. I will try a new location tomorrow since I'm away from the site at this time.

Opps...my wrong. I was getting mixed up with 12/3 wire. You're right...2 wires and a ground.

If it's single pole it might be getting power from only the one bar giving you the 120v your getting. The breaker needs to pick up both bars to give you 240v.

Talking Baseboard Heater Problem - Resolved

Thanks for the input. The problem is resolved. The location of the circuit breaker in the panel was the issue. It was not getting both sides of the required connection because it was not stradeling between the black and red main feed. As it was, both breakers were connected to one side instead of one on one side and one on the other. Thanks again.
