I am in the process of doing my basement and want to install two electric baseboard heaters. I plan on running 12-2 from panel to stat and running a 12-2 to a junction box. From the junction box I want to run a 12-2 to each heater and wire each heater indivually. I plan on using a 20 amp breaker and the circuit will be 220 volts. Does this sound OK
