Gas supply earth bonding

That current would not be a problem, provided it was not flowing through a person.
Of course not, but the reason for the guideline is obviously because, in the absence of bonding, such a current might flow through a person.

For those who quibble, people sometimes subtract a nominal 1kΩ for 'body resistance' from the theoretical thresholds of 23kΩ or 46kΩ (corresponding to currents of 10mA and 5mA at 230V, respectively, but that doesn't make much of a difference, given that the 10mA (or 5mA) is pretty arbitrary in the first place.

Kind Regards, John
