GE Profile GeoSpring 240V (FlexCapacity): Breaker & Wire Size
The circuit the GE Profile GeoSpring 240V (FlexCapacity) needs, transcribed from the manufacturer's own spec sheet, with the conductor and ground derived for the stated breaker.
Circuit Spec
| Voltage | 240V (240V dedicated) |
| Circuit | dedicated 240V circuit |
| Nameplate element wattage | Not printed by the manufacturer |
| Nameplate amps | Not derived (no printed wattage) |
| Manufacturer-required breaker | 30 A |
| Conductor for that breaker | #10 Cu |
| Equipment ground | #10 Cu |
The breaker is the manufacturer-stated value; the conductor and ground derive from that breaker. Under NEC 422.11(E) the overcurrent device must not exceed the rating marked on the appliance, so the nameplate on your unit always governs.
Models & Capacities
Representative models in this line: PH50S10BNY, PH50S10BPY. Capacities: 50 gallons. The circuit spec above applies across the line as published by GE Profile; confirm against the rating plate on the specific unit.
A Dedicated 240V Circuit
Every 240V hybrid is a dedicated-circuit appliance; GE Profile states a dedicated 30A / 240V circuit for this line, on #10 copper with a #10 ground.

Circuit data transcribed from the manufacturer: GE Profile GeoSpring 240V (FlexCapacity) specification, accessed 2026-07-11.
GE Profile's 240V GeoSpring takes a 30A / 240V dedicated circuit and, being FlexCapacity, can also be reconfigured to 120V (15A shared or 20A dedicated). GE does not print an element wattage, so the 30A dedicated circuit follows the manufacturer's stated breaker, not a derived load.
Frequently Asked Questions
What size breaker does the GE Profile GeoSpring 240V (FlexCapacity) need?
GE Profile specifies a 30A breaker on a dedicated 240V circuit for this line (models PH50S10BNY, PH50S10BPY). Under NEC 422.11(E) the overcurrent device must not exceed the rating marked on the appliance, so the nameplate governs. The conductor for a 30A breaker is #10 copper with a #10 copper equipment ground.
How many amps does the GE Profile GeoSpring 240V (FlexCapacity) draw?
GE Profile does not print a wattage for this line, so no amp figure is derived here. The manufacturer-stated 30A breaker governs the circuit (NEC 422.11(E)); read the rating plate on the unit for its exact draw.
Does the GE Profile GeoSpring 240V (FlexCapacity) need a dedicated circuit?
Yes. GE Profile states a dedicated 30A / 240V circuit for this line, and every 240V hybrid is a dedicated-circuit appliance. For comparison, a standard 4,500W resistance tank draws 18.75A at 240V, 23.44A at the 125% continuous sizing (NEC 422.13).
What wire size for the GE Profile GeoSpring 240V (FlexCapacity)?
#10 copper conductors for the manufacturer-required 30A breaker, with a #10 copper equipment ground sized to the breaker per NEC Table 250.122.
