Doing some minor work on an old installation which will first require upgrading the main earth and bonding.
The existing earth terminal is a bolt through the bottom of the metal fusebox, hidden down the side. There is no possibility of loosening the nut without dismantling the board and removing the main switch (why were they ever designed like this!).
As expected, the bolt is overloaded with various bonding wires, old main earth and various CPCs. I've added a new MET outside the box to terminate the new gas & water bonding cables and main earth but I still need to extend the main earth to the box.
I was going to go ahead and spend some time dismantling it and adding the earth to the existing terminal. However it may be quicker to drill another hole in the box and attach it to a new bolt with locking washers etc. However I'm uncertain if this would be an acceptable way to ensure a good earth connection. Any thoughts people?
