I have to move a Consumer unit approximately 6 mts. Had suggestion buy NAPIT technical to fit enclosure with terminal rail and terminals and then extend cables to new consumer unit. As the enclosure will not be readily available the terminal method would not be Maintenance Free. (If there was a...
I have a job where SEC are moving the mains cable for the property to allow for change of use of the area. This means that the tails from the new meter box will be through a wall and over 3 mts long. Therefore a Switch fuse /isolator will be required in the new meter box. Does it require the...
