Bonding verification?

[067256]

Been to look at a potential DB change.
Old style M/C Wylex board. TN-S supply. Water/Gas bond 6mm. Have checked visually and they are both conected and look in good nick.
Would these need upgrading or can i leave if mech and elec. sound? And make a note of this on the EIC?
16mm tails. 10mm Main bond.

as you say. if no sign of thermal damage, can be left .

TNS,, 6mm bond is fine not against any reg so wont even need a mention.

Just an old habit.....i put it on the cert to cover my hairy arse??

 

[telectrix]

it's compliant. only enter6mm in the " size of main bonding conductors" box.

What size is the supply?
6mm² complies for up to 60A, 80A and 100A would require 10mm².

Thought it was OK if no sign of thermal damage?

& as I was taught, check from the pipe, not from the end of the bond cable, back to the MET, for a good reading.

Only if it satisfies the adiabatic equation.
