Hello all! New to the site and first time poster.... I have a house that has six base board heaters with the thermostats that have a twist knob to control them. (thermostat is by the door and not on the heater). The original wiring in the house has 3 heaters feed off the same two pole 30 amp breaker. (jumps are made in the thermostat boxes).. Heres the problem....I have 240v coming into the thermostat box. At the heater when I break apart the connections and test the voltage I get 120 on each leg when reading ground to hot on the separate legs. When I try and read both legs together to show 240 it doesnt show any voltage....Ive seen this before but its been so long I cant remember what the cause is.....any help would be awesome... Thanks all love the site.
