Are there any situations where you would not bond structural steelwork. I have some vague recollection that there may be, but can’t think what they might be.
As always, depends on the legal scenario, if its a DNO PME offered earth terminal the bonding is required with the sizing well documented in the electricity supply regulations. For those unable to access a copy a popular guide book, BS7671 has reproduced the table for its readers.
All other earthing facilities are non mandatory, so its likely that you may have come across unbonded material.
As regards an earth connection itself, the ESQCR require an effective earth always.
