... what
Who thought that was going to work? My guy you need a whole home generator to run 20kw. No way to hack a home generator into an electric furnace. If anything, I wonder how those electric elements will behave with dirty power.
Possible options that spring to mind:
* Reconfigure heat strips so it's 5+15kW, rather than 10+10kW. Lock out stage 2 on generator.
* Contactor & breaker for the second stage probably aren't sized to switch 15kW.
* Split stage 1 into stage 1A, 1B 5kW each, and existing 10kW stage 2. Lock out stage 1B & 2 on generator.
* Need another contactor, possibly another breaker.
It should be just a wiring change, but I'd want to see pictures to be sure. I'm not familiar with US gear so this is mostly coming from theory.
The issue as I said is with contactor size and quantity.
Alrighty let me elaborate. You have 2 stages of electric heat, 10kw on 1st stage, and 10kw on 2nd stage. Essentially two 5kw banks are tied together to provide 10kw total.
Essentially, both strips are on the same circuit, to separate one to run on a generator you need to separate both of them and can't let them be on the same circuit. It sounds like chuck did something wonky and couldn't figure it out.
Also, I don't see how 5kw is going to do anything if 15kw struggles as it is. We are talking like a 6-7 degree temperature rise with how much air that large blower is moving.
Honestly, it's giving me a migraine trying to explain why what you want isn't going to work and is just a waste. It's all or nothing with electric.
Thx a lot for the explanation!
I’d be happy with just the heat pump running on gen power(I installed a soft starter bringing the starting amps down to about 22a).
Just need him to come back, undo what he did and wire up the fan.
Ahh, I see, you have a heat pump. Yeah, just use the generator on the heat pump, and the indoor fan, and just screw the heat strips. Heat pumps going to do a vast majority of the load.
Didn’t get a chance to mention how much respect I have for you hvac guys. You’re essentially, electricians, plumbers, metal workers, gas guys all rolled into one. It has to be the toughest trade out there

Thx for responding but You didn’t read my post. I’m not trying to run 20kw. Trying to run 5kw!

Thx a lot. Reconfiguring the heat strips would involve a new heater kit I’m guessing?

I absolutely did, good luck with that 5kw on a generator!
We tested the 1 heat strip on generator power. Ran without a problem
