continuity

[Richard Burns]

Will still give a much better clue than just connecting to the MET

True....

For main equipotential bonding, there is no single fixed value of resistance above which the conductor would be deemed unsuitable. Each measured value (if it's measurable) should be compared with the relevant value for a particular conductor length and size.

Surely can disconnect every cpc that could cause a parallel path to earth (boiler, shower, imm. heater etc) and then individually test each bonding cable to gas / water via long lead??
