Recommended checks before CU change

Former Community Member over 6 years ago

As most of you know I’ve only been qualified for just over a year and I’ve got a quote to do for a cu upgrade.

I know I’m nowhere experienced enough to do EICR’s yet, but what would you guys recommend I check/test before doing the cu upgrade and should I do these checks/tests at the quote stage?

I carried out my initial inspection and testing tonight and I’m concerned about the IR results, firstly though I think I done the IR test wrong on this board. I tested (global test) L-E, N-E then L-L, using the live busbar, results were .42Mohms on both L-E & N-E, but the L-L was 0.00???
