I am designing the circuit(s) for my basement apartment (cca. 800 sq ft) baseboard heating solution. I am planning to buy Berko HBB Series heaters and distribute them as shown in the below table. All have a voltage of 240/208.
Location Model Length(in.) Watts Amps
-----------------------------------------------------------
Living Room HBB1504 70 1500/1125 6.3/5.8
Bath HBB504 28 500/375 2.1/1.8
Bedroom HBB1254 58 1250/938 5.2/4.5
Hallway HBB754 34 750/563 3.1/2.7
My questions are:
- Should I split them into two circuits (living room and bathroom in one, bedroom and hallway in the other) or is it OK to keep them all on one circuit?
- Is the voltage a factor in determining the wire gauge? I know that the amperage is. E.g. if I split them in two circuits so that each circuit bears less than 10A each, can I go with AWG 14/3 even though the voltage is double than usual? Or simply put, which AWG should I use for either scenario from question 1.?
I have an extensive experience as a DIY electrician, I have pretty much rewired most of my house and have set up one 240/120 circuit for my dryer (used AWG 10/3). But this is considerably lower amperage so I am not sure what AWG to use.
