In fact, it is the only way to do it - by making use of an external relay.
This story has been going on for ages. The AIA inspector catagorically says it must perminantly be bonded. I figure if ever anything ever goes really wrong and I end up in court the guy opposite me is going to be the AIA guy. I understand implications of permenant bond and implications of relays (should it fail) but if the main man, the guy from the AIA says permanent - I do permanent.

The ECA are a bit wishy washy on it(apparently I'm not reading it right) - depends on how you read the rules.

Haven't picked up my new copy yet but hopefully there is some clarity.

The basic argument is - if the relay fails will your earth leakage still operate.
