Made 2 Measure: Is the PE Pre-Test feature important when testing EV chargepoints?

YOU ASK:

I NEED TO BUY AN ADAPTOR SO THAT I CAN USE MY MULTIFUNCTION INSTALLATION TESTER (MFT) TO TEST ELECTRIC VEHICLE CHARGEPOINTS. I’VE NOTICED THAT THE MEGGER EVCA210 ADAPTOR HAS A PE PRE-TEST FEATURE, WHEREAS ADAPTORS FROM SOME OTHER SUPPLIERS DON’T. IS THIS FEATURE IMPORTANT, OR IS IT JUST SOMETHING THAT’S NICE TO HAVE?

MEGGER SAYS:

We’d say that the PE Pre-Test feature is not only important, it’s essential! Before you carry out any other tests, it lets you check for potentially dangerous voltages that might be present on the PE. If such voltages are present, you must investigate and correct the fault before you continue with testing. If you don’t know about the potentially dangerous voltages and you start testing, there’s a risk of electric shock as well as damage to the equipment. To be absolutely clear, without the PE Pre-Test feature (or equivalent), you can never be 100% sure you’re safely testing a chargepoint. That’s why, when choosing your EV adaptor, this is a good feature to have. The EVCA210 will let you test the functioning and safety of all AC Mode 3 EV charge points in accordance with the IEC/EN 62851-1 and IEC/HD 60364-7-722 standards. As well as being compact, easy to use and portable, it is supplied with not only a Type 2 connector but also a Type 1, which is important if you want to test Type 1 plugs on tethered leads.
