Pool Heat Pump and amps

[Harry Golden]

Could use some help. I'm looking at buying a heat pump for my inground pool. Upgrading existing electrical service is problematic because current service is across a paved drive, up a rocky hill. I have 50 amp service box at pool now. Pool pump pulls 7 amps. Electrician says I can install 40 amp heat pump. Raypac makes unit with circuit ampacity at 40 amps and maximum breaker at 60. I don't know what that means in light of my current service. Can this unit be installed with my current service? Thanks

You're good. 40A is the size of the circuit but because of the characteristics of heat pumps you are permitted to use a 60A breaker to feed it.

Thank you, Sir. I noticed that raypac has a size larger model that has an ampacity of 42 amps. Based on the circumstances of my 50 amp service, would that be pushing it to purchase the larger size?

To answer your question properly I would need to come out to your place, better you should talk to your electrician. If he is experienced and competent he will steer you right.
