main bonding

[Ben Butcher]

Just a quickie, is there anything in the regs that says a main bonding cable cannot be joined? I have installed one for an oil pipe which has now been moved...

use a through crimp and you will be fine.

Should be a continuous run with no joints.

on this note does anybody know if it is allowed to bring a main bond to water or gas from a sub DB when the MET is on the opposite side of a building and miles away ??, i should know this but never come across it before .

joints are fine if they are permanent. i.e. can't be disconnected by removing a screw by a wet-pants.

 

[Andy78]

Is this not allowed then ?


One of three connectors I found in a main water bond last week. :annoyed:

that depends whether the sub main earth is large enough to carry the fault current .

that's terrible. it should at least have some green/yellow tape on it to stop the fault current escaping.

Rubbish

Did you just guess this answer? A main protective bonding conductor must be connected to the main earthing terminal 411.3.1.2
