Main bondage

[ipf]

I reckon this magical 0.05 figure comes from taking account of instrument error from trying to get a reading from the arse end of its scale.

'Titan Uranus' springs to mind

Answer to the first part of the question NO, second part (0.25ohms) come on get it sorted lol

Does main bonding in every circumstance always need to be under 0.05. main bonding in a house where the main water was moved has 10mm cable but resistance of 0.25 ohms!!>>

and as a side note if both bonds read 0.25ohms then once again there can be no difference in potential between parts
