Confirm your multi-function tester covers IEC 62955

"Chris’ paper suggests when testing EVSEs’ the key element in the trip current of the d.c. protection is the rate at which the d.c. current ramp rises," explained Brendan Beaver, manager of Metrel UK. "The rate of increase is defined by IEC 62955 and should be around 30 seconds."

"'So what' you may say, and the answer is the difference between a pass and a fail of the installation. And wasting time searching for a non-existent problem," he continued.

"I suggest that before you pay good money to buy a multi-function tester to check EVSE installations, you confirm that it to tests to IEC 62955!"
