I am having an extension on the side of my house and the meter box has to be moved to the new outside wall. The current tails from the meter to the cu is 10mm thick and about 2M long. When the meter is moved it will be about a 10M run to the consumer unit, will 16mm tails be sufficient or will it need 25mm tails?
cheers if anyone can help.
