CU replacement

[Griffin]

Hi, I am 3 weeks away from my Elecsa assesment and will be replacing my ageing wylex CU with a new dual RCD MK unit.

The meter tails are 16mm and will be too short for the new unit. I want to replace them with 25mm. (Main cut out is BS88 100a)

Do I call the supplier and get them to connect the tails on the day of change?

Does anyone have any easier or better suggestions.

Thanks

Griffin

You will have to pull the cut out fuse which is a job for your local DNO ( I'd personally pull it as there was no seal) , the tails remain the responsibility of the customer.

how about a couple of days before pulling the fuse and installing a dbl pole isolating switch (electricity company isolator) and on te day replace everyting from there ?
hope this helps

We always make the new tails long enough to reach the meter but connect them to the existing smaller tails (in a henly's type block) and get the customer to contact the DNO to connect the new tails.. I had my ELECSA inspection with this setup and he had no problems with it.
Hope this helps.
