Cnc machine bonding to structural steelwork

[Darkwood]

You can also reiterate that the install you have done hasn't reduced the safety of the current non compliant installation as required by the regs. Its however not as safe as current regs would require.

That would only apply if the structural steelwork aleady had bonding if required but it didn't meet say current sizing of bonding conductor due to changing regulations, where the bonding is absent but is required then no work can be done and signed off until the bonding is installed.
