The Megger EVCC300 Electric Vehicle Charger Checker is an EVSE tester designed for verifying the safety and operation of mode two and single-phase mode three (level one and two-phase level two) electric vehicle charge points. It can check chargers with SAE J1772 type one and type two connectors and is ideal for testing EV chargers after manufacture, installation, and repair, and/or as part of a maintenance routine.
In addition to a nuisance tripping test which determines whether the charger is likely to experience nuisance tripping of RCDs or GFCIs, the Megger EVCC300 Electric Vehicle Charger Checker includes four safety checks and four operation tests.
The Megger EVCC300 Electric Vehicle Charger Checker provides a comprehensive, convenient method of checking the safety and operation of EV chargers.
