    Evening All, I attended a job today to disconnect an Alarm System at a ground floor flat. On taking the consumer unit front off, discovered the incoming neutral tail to be 11 x 1.5mm single core cables which needless to say aren't all tight and secure in terminals. The incoming line looks to be...

    Meter tails in ceiling ?

    Hi all, I am moving a CU from next to the meter to about 1.5 meters away on an adjacent wall. Am I OK to run the meter tails through the ceiling void between the joists (plasterboard ceiling) to the new CU position or is a case of installing an isolator and 25mm swa? Many thanks

    Afternoon, Quick question. I’ve been to a job earlier to find a fault, but this connection was at the main switch. The first set of tails come from the meter and the second set are down to another duel RCD board. Looks doggers. Checked the Schneider manufacturing instructions and I was...
