Does this need to be bonded?

[LastManOnline]

It's a great document and one of the clearest explanations I've ever seen.
I'm not sure it helps this situation though other than establishing a helpful target let-go current.
See the diagram below and note the bit circled. That wouldn't be there in the situation this thread is discussing.

Isn't the point here that in all cases there's an 1000 ohm path straight to earth with at least 230ma current flowing, whether you add a parallel path through a unbonded pole (roughly 1000+ 110 ohms using value to MET) or a parallel path through an bonded pole (roughly 1000 + 66 ohms)?
Am I thinking about this right or losing marbles?!

No. Your marbles are very much where they are meant to be. But if I may offer my final comment on this post, it's this. Bonding as a topic is the "gift that keeps on giving" from the point of view that since I, ve been an apprentice no other single electrical subject has caused me more "head scratching" (along with the occasional headache.) The electrical game would be very boring without it

By standing on the soil you'd probably be wearing shoes that provide some level of insulation. Touching a metal pole with bare skin will give a lower impedance to earth. Also it would be a case of resistors in parallel so the two paths combined would give a reduced total impedance to earth.

Hi guys,

Similar situation here, except, the aluminium tunnel support hoops are bolted to a new concrete pad.

I havent started yet, but would the hoops need bonding?

The only thing that is going in is a small db, and two double sockets on a ply board mounted on a bespoke metal tube frame at one end.
