I've got a Gibson GQ3RA-24K I've been using it with out the heat coils. It's on a double 30amp breaker with 10gage wire. I'm wanting to hook the heat coils up but don't know if that wire will be enough. What size wire should I have?

What size heat strip do you have? You can run a 5 kw on a 30 amp.

I'm not really sure. So with 5k it will run the heat pump and coil on 30?

It's not marked on the tag like it should be.

Also when I do hook the coils up how do I check to see if they work, they don't kick in unless it's to cold for the heat pump right?

If there is more then 1 coil it is larger then a 5kw. Once it is installed turn the t-stat to emergency heat. This will bring the electric elems on if wired correctly.

My thermostat is a ritetemp it works for heat pumps with aux heat but has no emergency heat.

It's a 6022 ritetemp.

If it is set up fro aux heat all you should need to do is turn the heat setpoint about 5 degrees warmer then the temp inside and the aux should come on.

Thanks.

I've got two coils so can I set it up to run just one. With just one the 30 amp break will be able to power the coil and the compressor?

Acorrding to this for a 5 kw you will need a 40 amp breaker. Take a look.

So I've got two coils does that mean it's 8 or 10kw?

What does the 60`C CU , 75`C CU ,and 90`C CU mean?

Yes I would say it is a 10. Where are you seeing the c cu?

It's on page 5 of the link you posted. Across the top of the table.
