Extech ET11 GFCI Receptacle Tester for Type B Electrical Outlets

The ET11 is tailored for electricians, inspectors or maintenance personnel who need a quick, reliable check of standard three-wire receptacles—including those protected by a ground-fault circuit interrupter (GFCI). Just plug the unit into an outlet and the built-in LED indicators show whether the wiring is correct or if faults exist such as open ground, open neutral, open hot, hot/ground reversal or hot/neutral reversal. Importantly, the ET11 also triggers the GFCI to confirm it will trip as intended, offering a layer of safety testing. The device is rated for 110–125 V AC circuits at 50/60 Hz and features a test-legend printed on both sides to accommodate receptacles where the ground pin may be at the top or bottom. Removal from the outlet is simplified via an ergonomic pull-bar, reducing stress on the device and ensuring safe handling. Durable and field-ready, the ET11 is a convenient tool for pre-installation checks, maintenance rounds, property inspections or any job where outlet integrity and GFCI functionality must be verified efficiently.
