How Many Amps Does a Salt Water Chlorinator Use?

Salt Water Chlorinator draws about 1.3 amps at 120 volts (150 watts running). At 1.3 A, a salt water chlorinator fits comfortably on a standard 15 A or 20 A household circuit.

Voltage

Amps = watts ÷ volts. Enter the wattage from your appliance's nameplate or label for an exact figure.

Breaker and circuit for a salt water chlorinator

At 1.3 A, a salt water chlorinator 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.
