Switched fuse on meter tails ?

[sidekick]

I have a consumer unit change which also means relocating the unit approx 16m away from original position where meter is.
I have (as i always do) arranged for YEDL to come and fit an isolation switch first.
Once this is done the new meter tails will go from the switch under the floor for approx 15m and back up to new position.

My questions are -

1. Do i need to use any form of protection for the meter tails uder the floor or just clip to the underside of the joists?

2. Do I still need to fit a switched fuse after the isolation switch?

as long as they follow same route and armour is earthed.

Perfect - thanks for confirming.

I would just add that you should make sure the armour is earthed at both ends (i.e. armour wire is in parallel with the 16mm earth) to keep the cable Zs down to a value that allows the sub-main to meet 5s disconnection on your chosen fuse on any internal fault.

Will do - thanks!
