Met

[kingeri]

Imagine the scenario, you have two CU's in an installation and no external MET. The main earthing conductor goes to the earthing terminal in one of the CU's and the main bonding conductor goes into the earthing terminal of the other. The earthing terminals of the two CU's are joined together with 16mm. Which is the MET / is this permitted? I wouldn't do this, but I've come across it a lot. The MET can be external to the CU or it can be the earth bar inside the CU, but can it be 'split' across two CU's (if you see what I mean?).

Tamper head screws might be the way forward but that might only increase their curiosity!

Totally pointless exercise!!

Hows about every screw at the met and cu should be shorted thus welding them in their tightened position? That'd stop the buggers!!
