EICR recommendations

Just a quick one. Testing a house that's install is about 20 year old. Obviously hasn't got a metal clad DB, earthing is only 10mm. Would you put these down in the reccomendations? Even though these items were perfectly fine when it was installed?

Non metal fuseboard I personally wouldn't comment on but the 10.0 earthing conductor I would.

What size are the L/N tails?

 

[normanton]

What size are the L/N tails?

16mm.

 

[westward10]

16mm.

I go by up to 16.0 line conductor then 16.0 earthing conductor, simple me.

If it's TNS then the 10mm may well be adequate....

What size is the dno fuse?

Forget the pretty pictures in the OSG

I'm with Murdoch - TNS or TT and that 10mm is probably more than adequate. I recently installed a 10mm on a rewire because it was a tricky run and 16mm would have made it much harder to pull. Adiabatic only needed a 4mm, so 10mm more than enough.

 

[telectrix]

as above.10mm earthing with 16mm L & N tails. no code, no action.
