Electrical safety leader, Martindale Electric, has unveiled the first of its kind EV socket tester. The BZ820-EV performs functional electrical checks on electric vehicle supply equipment (EVSE) charge points with Type-2 connectors.

Ideal for contractors and installers, the single phase BZ820-EV is the optimum first-line tool for checking EV chargers fitted with Type-2 connectors. It’s quick and easy to use, but thorough – detecting 28 wiring fault conditions and also checking and indicating the voltage supply level as high or low.
Correct polarity is indicated by three flashing green LEDs and a continuous audible tone, while fault conditions are clearly indicated by three red LEDs and an intermittent warning buzzer. Socket polarity and earth wiring faults, meanwhile, are identified by a combination of red LEDs. Plus, a look up chart on the tester provides basic fault diagnosis.
With the BZ820-EV connecting directly to an EVSE charging point using the Type-2 connector, the integral CP mode, 4-position slider switch allows vehicle states to be simulated: - no vehicle connected is (A), vehicle connected but not ready to charge (B), vehicle connected and ready to charge, (test mode C).The additional “E” (error) setting simulates failure of the CP signal, which causes the charger to inhibit charging.
Additionally, LEDs on the integral Type-2 plug show the status of the CP signal and if the voltage supply is present (L1), while there’s also fast and easy testing for the correct wiring of L, N and PE in a 3-wire cable.
Like all Martindale Electric socket testers, the BZ820-EV is designed and supported in the UK, with the company’s well-known commitment to reliability and customer service.
It’s suitable for indoor and outdoor use, but in dry conditions only, and the product is designed, as with other socket testers, to be used as a first line tester not as an alternative to a full installation test.
With the addition of the BZ820-EV, Martindale continues to lead the way in both simple and advanced single-phase and three-phase testing capability for domestic, commercial and industrial applications.
