I am currently working on a series of Residential HVAC Chillers with integral pump packages. Our largest unit has the following stats. RLA=499, MCA=509, Max Fuse =600 (HACR breaker can be higher). 240/1/60 main 115/1/60 and 24/1/60 control.

Has anyone worked on residential HVAC Services this size?

We are mounting the Fused Disconnect on our unit for ease of customer installation as well.
