Electrician EV Charger Tester

For all EVSE EV Chargers

An Essential Tool For Ensuring Proper Operation of Your Equipment

Durable, self-powered and small enough to fit in a tool box, EVSE LLC’s Electrician tester is a must for any EV charger installation professional.

These hand‐held, weatherproof units allow installers to check new electric vehicle chargers after installation, verifying a number of vital power and safety requirements as they simulate the connection an EV charger makes with an electric vehicle. Simply plug the charger’s J1772 connector into the Electrician’s receptacle, flip the switch button and the LEDs will indicate the actual amperage and voltage.

The Electrician also lets you know if the pilot signal is operating properly. For testing the GFCI in the EV charger, just flip the switch to make sure this safety function is working properly.
