Tails upgrade

Davem · May 24, 2013

Hi, just a quick question I am upgrading a cu and partial rewire. Now the tails from the cutout are 16mm and go in to a teleswitch, they then comeout and go in to a multiwatt reader then in to the ccu. Obviously I want to use 25mm tails after the meter so do I get the electric board out to upgrade there part? Can the teleswitch be removed by them ? At my house supply comes in to cut out into meter then in to isolator then in to cu.! Any advice appreciated I am new to the game also so be kind

16mm tails in fee air will carry 100A all day without getting anywhere near 70deg.C. it's time the rule book was rewritten without the stupid safety factors they have now.

I was told by elecsa that all tails on ccu upgrades (domestic) must be 25mm no matter what size fuse. Which I think is a bit silly on small flats or houses.

They're getting as bad as the nic for making up their own rules.
