Greetings to all!
The CEC and NEC is close on many levels, most in fact. So any input here would be great!
I am an electrician who is installing the electrical for a small outside heat pump. The heat pump requires 20A 208. I have that covered. My questions are about disconnects and protection.
So it goes...
Ctrl Head---3Pole disconnect--3c14---MAIN
Ctrl Head---3Pole disconnect--3c14---UNIT---2c10--PANEL
Ctrl Head---3Pole disconnect--3c14---208V
There has to be a 3 pole disconnecting means between the ctrl head and main unit.
The main unit is located outside.
My questions are:
1a. Does the main unit have to have a disconnect?
1b. If so does, the disconnect have to be within sight (in this case, outside in a wet area)?
1c. If so, does the main unit disconnect have to have lockout capabilities?
1d.Does the main unit need to be protected by ground fault protection (either HP rated unit or an expensive GFCI breaker).
Control Units (located inside, basically a fan with coolant lines going into it)
2a. Do the control unit disconnects have to be within sight?
2b. And if so, do they have to have lockout capabilities?
