Rcd for tails?

[J.C.E]

Up coming job....
fb currently in downstairs hall in a little cupboard- along with the head and meter.
job is a rewire anyways- but customer wants new fb moved into garage- on other side of wall to where it is at the minute. (Directly on other side of wall- litterally just popping through wall)

Run is <3meters but i will obviously have to drill a hole through the wall for my 25mm tails and 16mm earth

was planning on having a switched isolator where the old fb is- then tails into garage to new fb.

but as tails go through wall- guessing they need additional protection- do this by a upfront 100ma rcd?

cheers guys

Passing through a wall is not something which requires additional protection by RCD. And even if it did, a 100mA RCD is not appropriate for providing additional protection - only fault protection.

Just a sw fused isolator will suffice then

just an isolator. no need for fused, although that is an option. maybe a wylex KMF with 80A fuse.

What's the point in moving if then if your having to have something there still??
Surely it's making it more costly and inconvenient??

and i'd fit a short length of 25mm pvc conduit through the wall then feed tails through that.

would you get 2 25mm tails and a 16mm earth though a 25mm conduit? might be a bit of a squeeze !!!

as long as it's a straight piece, no bends. still be room for a mouse.

As long as it's made from non-combustible material

Then that is a a good idea

If it's just above 3m why bother with anything. Who's to know?

Tin hat . On
