GE Profile GeoSpring 120V Plug-in (FlexCapacity): Breaker & Wire Size
The circuit the GE Profile GeoSpring 120V Plug-in (FlexCapacity) needs, transcribed from the manufacturer's own spec sheet, with the conductor and ground derived for the stated breaker.
Circuit Spec
| Voltage | 120V (120V plug-in) |
| Circuit | shared or dedicated 120V circuit (FlexCapacity) |
| Nameplate element wattage | Not printed by the manufacturer |
| Nameplate amps | Not derived (no printed wattage) |
| Manufacturer-required breaker | 15 A |
| Conductor for that breaker | #14 Cu |
| Equipment ground | #14 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: PF50S10FPY, PF40S10FPY. Capacities: 40, 50 gallons. The circuit spec above applies across the line as published by GE Profile; confirm against the rating plate on the specific unit.
Can It Share a Circuit?
The rule combines two independent NEC requirements: 210.23(B)(2) caps equipment fastened in place at 50% of a 15A or 20A multi-outlet circuit, and because a storage water heater is a continuous load (NEC 422.13) the circuit must carry 125% of it (210.19(A)/210.20(A)), so the largest raw nameplate that fits is 6A on a 15A circuit. A listed unit may be cord-and-plug connected under NEC 422.16(A). This shared-circuit question applies only to the 120V plug-in class.

Circuit data transcribed from the manufacturer: GE Profile GeoSpring 120V Plug-in (FlexCapacity) specification, accessed 2026-08-12.
GE Profile's 120V plug-in is FlexCapacity: as shipped it runs on a 120V, 15A shared branch circuit (a standard plug-in), and it can be field-converted to 240V on a dedicated circuit. GE's own literature is inconsistent about the dedicated-circuit amperage of the converted unit (one sheet shows a 25A dedicated circuit, another 20A), so we publish only the unambiguous shipped configuration; follow the configuration on the unit's rating plate. GE does not print an element wattage, so amps are not derived here.
Frequently Asked Questions
What size breaker does the GE Profile GeoSpring 120V Plug-in (FlexCapacity) need?
GE Profile specifies a 15A breaker on a shared or dedicated 120V circuit (FlexCapacity) for this line (models PF50S10FPY, PF40S10FPY). 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 15A breaker is #14 copper with a #14 copper equipment ground.
How many amps does the GE Profile GeoSpring 120V Plug-in (FlexCapacity) draw?
GE Profile does not print a wattage for this line, so no amp figure is derived here. The manufacturer-stated 15A breaker governs the circuit (NEC 422.11(E)); read the rating plate on the unit for its exact draw.
Can the GE Profile GeoSpring 120V Plug-in (FlexCapacity) share a circuit?
Can share a circuit. Listed by the manufacturer for shared-circuit use; the unit stays within 6 A (15 A x 50% / 1.25 = 6 A). The rule: NEC 210.23(B)(2) (fastened-in-place equipment 50% of the circuit) combined with the 422.13 continuous load carried at 125% per NEC 210.19(A)/210.20(A). A listed unit may be cord-and-plug connected under NEC 422.16(A).
What wire size for the GE Profile GeoSpring 120V Plug-in (FlexCapacity)?
#14 copper conductors for the manufacturer-required 15A breaker, with a #14 copper equipment ground sized to the breaker per NEC Table 250.122.
