Square D HOM220GFI GFCI Breaker for new Calimar VS Pool Pump?

[YuQueen]

Hello all,


New here. My old Pentair WhisperFlo single-speed pump just died a few days ago, and I’ve ordered the Calimar 3HP variable-speed pump for my 20,000-gallon pool. To use the new pump, I’ll need to upgrade my equipment from 115V to 230V.


I’ve seen several posts in this forum about GFCI breaker tripping issues when not using Siemens breakers. I currently have a Square D Homeline panel. Right now, I’m using:

• A single-pole 20A GFCI breaker for my 0.75HP pump and 250K BTU heater (draws a maximum of 5 amps).
• Another single-pole 20A GFCI breaker for the pool light, outlet, and booster pump.

I’m considering two options:

1. Replace the existing pump and heater breaker with a Square D HOM220GFI and rewire accordingly, leaving the other breaker untouched.
   Pros: Easier—just a swap and rewire.
   Cons: May trip since it's not a Siemens GFCI breaker.
2. Install a new Siemens sub-panel and use a 20A double-pole Siemens GFCI breaker for the pump/heater, and a 20A single-pole Siemens GFCI breaker for the rest.
   Pros: Harder due to the rewiring effort, but likely more reliable and may prevent nuisance trips.

Which option would you recommend? Has anyone here had experience using a Square D Homeline GFCI breaker with a variable-speed pump?


Thank you—your help is greatly appreciated!

Installed my Calimar 3HP VS in Sept 24 using a

Thanks! Do you run the pump all day long? how is the Calimar pump working for you?
