Shut off breaker to base board heater, disconnected, moved base board heater , reconnected. Turned breaker back on and for some reason no power . Tested the line at the base board to confirm. Cannot find any reason why I have no power.
If the breaker (you mean from the main board?) is turning off there is a line fault or short somewhere. If the breaker is not kicked off then there is a loose connection or maybe a small blown fuse in the base board heater unit itself.
SOURCE: electric baseboard heater hums while running
is a 60 cycle hum, resonating with the power. check screws that mount it nothing to really worry about
SOURCE: marley md26 line voltage thermostat
The Black Wires from the md26 are your load(the heater) and the red lines are your line(power). The lines are also paired up on the thermostat with a red and black on the left and are red and black on the right. In the actual heater connect the black to the black wire and the white to the white and connect the grounds. In the thermostat connect the black from the heater to left side black( remember there are pairs left(black, red) right (black, red) and the white to the right side black connect the black from your power to the left side red and the white from your power to the right side red. Should be ready to go.
SOURCE: Electric baseboard heat not getting hot
Is your fuse box and main power source large enough to handle the full load if all are turned on at the same time? Are you uses two pole breakers? you might only be feeding with 110 volt. This would prevent them from getting very hot.
SOURCE: Properly installed electric baseboard heater won't work.
I am an electrician. You must measure the voltage across the black and red wires. Measuring each wire to the neutral will not cut it. If both your red and black wire are on the same phase the heater will not work.
To double check your wiring, measure the voltage across the two screws feeding your subpanel, they should be 240v or 208v depending on your power company. Then do the same at the breaker feeding your thermostat. Again it should read 240v.
If you have no potential across the screws it is possible that you installed an incorrect breaker. Not all breakers with two screws on them are 240v breakers. There is what is called a twin or split breaker that has two screws that are on the same phase. These are for wiring two 110v circuits, when you run out of spaces in the panel.
Double check everything. This is a relatively easy circuit to wire, even for homeowners. If the heater does not work them something is wrong so do not leave the circuit energized.
SOURCE: Problem wiring 240amp baseboard heaters
12 gauge wire sounds under sized for the application. And 20 amp 240 v breakers might be sufficient if you where wiring the heaters separately. But be sure that your wiring is not romex - because romex is an insulator and is not permitted in conduit. I would suggest that you up size your wire to 10 guage and your breaker to 30 amp as well. Then double check your heater wiring connections to insure that they're wired the same throughout.
