Hi all i have had a look at future upcoming job of cu change at the moment im not registered now how can i do a cu change for one of my assesor jobs when main fuse(80A)has to be removed and would be replaced with i believe 100A correct me if im wrong as current installation is TNS i believe and has no isolation switch between meter and current individual cartridge fuses any help or corrections would be most welcome:):)

Kitchen cupboards are not a good idea as they are a pain.

As to the cutout, if you feel competent enough, you can snip the seal and pull the fuse.

However, make sure all loads have been removed first, ie ALL main switches off.

The only possible problem is that some fuse carriers come apart if the fuse is tight so beware.

Im assuming that the DNO are coming to uprate the fuse to 100A? You are not really allowed to do this yourself.

After you are done then just reseal or contact the DNO to come and do it for you.

From my understanding no one has ever been prosecuted for doing this, unless they were helping themselves to free electricity!

Carry on and pull the fuse or contact the local DNO and they will (may) do it for you.

Indeed.

They will supply all registered sparks with the seals, not just those with the NIC:)

I would love to see some evidence of someone being prosecuted for pulling the fuse to work on an installation.

I think the EAWR would be the trump card in court.:)
