Hi! Would love your input.
We recently renovated a condo. The condo building main breaker panel is 150 amps, the panel in the condo unit is 200 amps. The electrician who installed it didn't think that was an issue, but there was a 2 stage HVAC system installed. He only hooked up one stage because he was worried that if the 200 amp panel tripped it would trip the system for the whole building. The heat hasn't been keeping up in the winter because the other stage isn't hooked up. The new electrician thinks he can hook up the second stage without the breaker being tripped.
I can't find the code section that would relate to connecting a 200 amp panel to a 150 amp panel. Are there any code issues here or things we need to worry about?
Thanks
