That looks like it could be a BS3036 rewirable fuse ,

We should have a gallery for things such as this.

just my opinion though.

I'd push towards the 3036 re-wireable too, along with solid brass links for the neutrals.


@ SirKit......kind of like a black museum you mean....

Unless you can definately verify....not possible without breaking seals.....just write not ascertained on the cert.

Hi
Thanks for the speedy reply knowledge is the key !!!

Also I'm I right in classing the system as TNC-S the only reason for me asking is that the cutout is old and I thought that TNS was a more popular earthing system.

Thanks again

Depends on whether the earth conductor is coming off the sheath, or tapped off the neutral. You can't really see from the pic.

You could try to confirm what earthing system it is by taking loop readings from line to earth and from line to neutral at the board, if they are very similar then the chances are it will be TN-C-S....

with the cut out like it is and the earth wire from the area its petruding i would say its a TNS , agree with pevvers do a test see what the readings are max 0.35 tncs or 0.8 tns
