Baseboard Heater Problems... Help!
I have wired two Marley electric baseboard heaters (240v) to a Programmable Thermostat. The problem is, nothing is working…
Here are the stats:
BASEBOARDS
Baseboard #1 is 3 feet long, 3.1 amps & 750 watts.
Baseboard #2 is 4 feet long, 4.1 amps & 1000 watts.
WIRE & CURCUIT BREAKER
I am using 12/2 wire with ground, and connected to a double-pole 20amp circuit breaker. The black wire is connected to the double-pole 20amp breaker, and the white wire (labeled with black tape) is connected to the double-pole 20amp breaker.
THERMOSTAT
Honeywell RLV430 Programmable Thermostat
SETUP
Sequentially it goes, Main Electrical Box >>TO>> 1st Heater>>TO>>2nd Heater>>TO>>THERMOSTAT (all using 12/2 w/Ground wiring)
In the first heater, I have connected the white wires from both lines with one of the two connection wires on the left side of the baseboard. I did the same with the black wires and the other connection wire on the left side of the baseboard.
I did the same in second heater (white to white and black to black). The White and Black then lead to the Thermostat and connect with it there and terminate Ground to the metal box.
After wiring everything and turning the breaker ON, it seems like the breaker doesn’t stay in the ON position. It goes to a Neutral position (not ON or OFF) and nothing works. I even tested the Heater Line right above the box in this Neutral position and do not get a signal. I.E. It is not hot according to my tester.
Where should I start in troubleshooting this?! Any help you can provide would be appreciated.
Thanks,
MC
