Recommended checks before CU change

Former Community Member
Former Community Member
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?

    Tillie:

    Do ring circuit continuity at a convenient socket.




    Tillie, loads of practical advice with which I agree, but if you have the fusebox cover off, why not do the ring tests from there?


    I might add that I cannot remember being taught on my course that rings could be tested at any point, but it is occasionally easier than in the CU where the tails may be short or at the back.


    Then again, if you open a socket and find that it's a spur, it's back to plan B. ?
