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?

If there's stuff plugged in I usually test at 250V, I'd second Mike with the L+N to E, if you still have low readings you may have to test individual circuits to locate faulty circuit(s) or make a judgement call if you feel that the connected load is affecting the readings.
