I'm trying to add a swim spa to my duplex home and need help with the calcs to see if I need a panel swap or not. Briefly there is 3 phase service with a 4 wire 2/0 UG feeder in 1 1/2inch PVC. Each unit has its own single phase 125 A panel and one additional 100 A panel for house common load like 600 W of outdoor lighting and a few service outlets. The spa would be added to the house common panel. The spa mfg says I need one 40 A and one 60 A breaker to serve the four 5 HP and one 4 HP motors and an 11kw elec heater. Its all 220 V. My question is on the load calcs; can someone please confirm that all spa loads are figured at 100% demand, and if I need to figure any of the motors at 125% as well? Thanks alot, this is my first time post and the website looks great! (Might have posted this twice so please excuse any errors!)
