After roughing in a new house and before final, we customarily get what is called a "service release". This is just an inspection with a few circuits connected to allow the POCO to connect power. This is mostly for HVAC to be turned on to acclimate the house for flooring, painting, etc.
When I was preparing the panel for the service release I asked the HVAC installer what size breaker he needed for his unit as it was not on site when I left. He told me a 30A breaker and that's what I put in.
Now I'm back doing trim-out and I just thought I would look at the unit to see what the nameplate said. The "Max Breaker" size was 40A. I know the 30A is legal but I don't want to be called back for nuisance tripping. However, this unit has been running for a couple of months and no reported tripping. Since this house is quite a distance for me to drive, do you think I should swap the breaker out for a 40A?
