Hi All,
When I carry out a Ze test , I test at the CU input with all load circuits isolated, ie with the main switch off.
I disconnect the main earth from the cu and attach my earth test lead lead to it. That way I am looking backward down the supply (as a supply characteristic.)
When doing a PFC, I reconnect the main earth but should the main CU switch also be off.
Thanks
