Hi everyone,
My new Intelliflo pump and Hayward SwimClear cartridge filter arrived within last couple of days, so this weekend will be spent re-plumbing the pad and installing the new equipment. The pump is replacing 16 year old Jacuzzi products (1HP energy saver pump and 27" Sand Filter).
My question is regarding the sub-panel and the breakers.
Currently, I have an old Intermatic subpanel (Model T200004R) with integrated mechanical timer and four breaker slots setup this way:
- Slots 1&2 : 20AMP Dual Pole breaker (not GFCI which I will remediate) wired to timer.
Timer controls the old Jacuzzi pump (nameplate rated @7.0 amps @220V), Polaris Booster Pump (nameplate rated @6.3 amps @220V
and a Goldline SWCG (rated @1.0amps @220V); Total rating of 14.3amps, so no issue with 20AMP breaker for the old equipment.
- Slot 3 : 15AMP single pole GFCI for pool light (old Fiberstars fiberoptic w/Jbox [light source] about 50 feet from subpanel)
- Slot 4 : 15AMP single pole GFCI for branch circuit to garden shed (1 15amp outlet & 2 ceiling lights) and pool deck outlets (3 15amp outlets)
The Intelliflo is name-plate rated @16amps, so clearly the new pump, booster pump, and SWCG will exceed 20amps using the nameplate rating.
The California Energy Commission's tests of the Intelliflo @3450RPM (full output which I don't think I will ever use) tested @2720 watts (12.36amps drawn @220V).
So even @the measured current draw, it seems the current 20AMP dual pole breaker is too small to handle both pumps and the SWCG.
But with only 4 slots in the subpanel, if I install 2 GFCI 20 AMP double pole breakers, there are no slots left for the pool light circuit or branch circuit.
My initial thought was to replace slot 3 with a dual-pole 1/2 size 20AMP breaker and move the timer/booster/SWCG to it (no need for the Intelliflo to run off the mechanical timer). Then let the GFCI in slot 4 handle both of the 120V branch circuits since there's really no load there.
This would leave the booster pump and SWCG without GFCI, but that is their current state anyway & never had an issue in the rain or while wet.
I really don't want to replace the subpanel (don't even know if there is a similar model with more breaker slots).
Any options or suggestions?
TIA,
SteveK
