How Many Amps Does an Electric Fence Charger Use?
Electric Fence Charger draws about 0 amps at 120 volts (5 watts running). At 0 A, an electric fence charger fits comfortably on a standard 15 A or 20 A household circuit.
Amps = watts ÷ volts. Enter the wattage from your appliance's nameplate or label for an exact figure.

Breaker figure is guidance for a simple resistive load, sized at 125% for continuous running — confirm against the nameplate and a licensed electrician.
Electric Fence Charger amperage at 120 V and 240 V
Same 5 W load — the current halves when the voltage doubles. Electric Fence Charger is typically a 120 V appliance in US homes.
| Draw | Watts | Amps at 120 V | Amps at 240 V |
|---|---|---|---|
| Running | 5 W | 0 A | 0 A |
Breaker and circuit for an electric fence charger
At 0 A, an electric fence charger fits comfortably on a standard 15 A or 20 A household circuit. For a dedicated circuit, guidance is a 15 A breaker with 14 AWG copper (75°C terminations) — sized at 125% of the running current because it runs 3+ hours at a time (NEC 210.20).
Guidance only — actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.
