Milwaukee 2223-20 Gfci Receptacle Tester

Product Description

The Milwaukee Electric Tool Corp 2223-20 is a GFCI receptacle tester built for electricians and inspectors who need fast, reliable outlet diagnostics on the job. The unit plugs directly into a standard 120-volt receptacle and uses LED indicator lights to read wiring conditions instantly. An over-molded grip adds durability and comfort during extended use. The 2223-20 also features a dedicated GFCI test button with a visual indicator light that confirms whether the GFCI circuit is functioning correctly. It is a compact, no-battery-required tool suited for residential and light commercial electrical work.

This tester is used on standard grounded 3-prong receptacles wherever outlet integrity needs to be verified — rough-in inspections, service calls, pre-occupancy checks, and troubleshooting callbacks. Electricians, home inspectors, and facility maintenance technicians commonly carry the 2223-20 as a first-step diagnostic tool before pulling a device or opening a panel. It is appropriate for both new construction walk-throughs and existing installation audits.

Key Features

• LED indicators identify six distinct wiring conditions: hot/ground reversed, hot/neutral reversed, open hot, open neutral, open ground, and correct wiring
• Integrated GFCI test button with visual activation indicator confirms proper GFCI operation
• Over-molded grip construction for durability and handling comfort
• Plug-in design requires no batteries or external power source
• Compact form factor fits standard tool pouches and electrician bags

Compatibility

Designed for use with standard 3-prong grounded 120-volt receptacles in residential and light commercial applications, including GFCI-protected outlets requiring functional verification.

Installation Notes

No installation is required — the 2223-20 is a plug-in diagnostic instrument. Electricians should confirm the circuit is live before testing; the tester requires power to display accurate wiring condition results. When a fault condition is indicated, de-energize the circuit at the panel before servicing the receptacle or wiring. Work performed on branch circuits should comply with applicable NEC requirements and local authority having jurisdiction (AHJ) guidelines.
