    Meter Tails

    Hi. I've recently moved into new house. The meter box and consumer unit are installed in cupboard underneath the stairs, however they are approx. 1.5m apart and the tails are surface mounted. Should they be encased in trunking so as to protect them from damage. Thanks

    Meter Tails hanging loose.

    Been to a job to see this. I'm guessing that when the old CU was replaced the sparks didn't bother to remove the old meter tails - they were live and just had a couple of wraps of insulation tape round them.

    AM3 Tails Stuffing gland

    I seem to have a run of jobs of upgrading consumer units. Previously I've used 32mm standard stuffing glands for the tails when I have needed to.
