ELECSA Certification Scheme Regulations Clarification (ELECSA Assesment)

His pic shows a 60A switch-fuse.

Just wondering why, is it a long cable run and perhaps inappropriate cable or DNO sw/fuse (does seem a bit old for DNO)?

I suspect the reason/ ownership of the switch-fuse is long forgotten.

I don't know, might be some clues on that WPD bit of paper

It's not there because the run is too long, definitely <<3m. Unsure why it's there but works well for my assessment as no need to arrange de-energisation, assuming we all agree that I can just upgrade the main earth to where the connector is currently (changing it to a proper earth terminal).

It's an ex council house that he bought a few years ago. Last inspection 1998!

Well that Wylex standard board will have a 60A switch so maybe it is to protect that along with the 16.0 tails?
You can probably get away with a 10.0 earth seeing as circuit protection is provided by the fuse at the switch-fuse.

 

[Nickj]

As he new board will have 100A main switch should I upgrade the tails between CU and the switch fuse?

I think not as the cable is still protected by the switch fuse?

Im now going along the lines of just needing to upgrade main earth from CU to the earth connector in the enclosure and upgrading bonding to 10mm^2.

I'll check all wiring before I go ahead with the swap so that if there are any issues I can address them before switching over.

Still in shock that council want £164 for me to notify!

Have you thought how to run the new tails, room behind the door frame?

Errgh?

 

[westward10]

Existing tails should be okay, have you checked the fuse? Upgrade bonds and earth to CU, 10.0 is fine.

!

Will the old tails be long enough?

Pull new earth through using the old one, that's always straight forward ain't it

 

[Nickj]

Will I need to run new tails? If I was going to would running it through the cavity as they are currently but in flexible conduit suffice?

There would be space behind the door to run some trunking with tails in. I could run it in trunking and then drill diagonally into the box...

Putting the tails in some flexible conduit, may prevent damage as you install them. If you can find another way, it would be better IMO

PS you mate needs to get his paintbrush out, or are you having to do that as well!

 

[Nickj]

I could come across and down I trunking then through the wall into trunking for 50mm or so then straight out into enclosure. It wild be less than 3m (much less). I hate the look of trunking and so will my friend. Is it more regs friendly to do it this way?

We are definitely in agreement that if I replace tails I only need to replace to the switch fuse? Similarly wth the main earth to the connector?
