Hi all, I have a GE TMC4020CCU Powermark loadcenter (Canadian model) with 40 spaces. The circuit diagram indicates that it can take 80 1/2" breakers (THQP) in any position. But it then says the maximum number of 2 pole THQP breakers is 38. What I don't understand is why this number is not 40...

We are replacing our old 4 line thermostats for our electric baseboard heater. They are 240. Anyhow, I just got the Aube TH115 -A 240 D to replace an old Thermostat (Electric Controls, Inc is the manufacturer) AUBE Product...

So I'm trying to figure out the code for when to use double pole breakers on single leg circuits with regard to multiple circuits in one junction box. Lets use the last example I had to deal with. If I had a fully split receptacle, as in two hot and two neutral, do these circuits need to be on...
