supplementary bonding

[timo]

Just another quick one on a CU Swap. no bonding to bathroom, ktc etc. If the circuit is protected by 30Ma and the Water and Gas etc are bonded and also .4 disconnection is met then no requirement for bonding. Do you N/A the box on the check list?

Another requirement to omit supplementary bonding is a continuity reading of less than 1667 ohms between extraneous conductive parts and conductive parts....as long as all requirements are met them N/A in the tick box. I always note the continuity reading as well in the comments section.

Thanks for that
