I would say so because the metal frame does represent an extraneous conductive part. (411.3.1.2 item v)Client wants 2g socket in greenhouse, obviously IP rated,will be supplied from Rcd, the greenhouse consists of metal frame work on the ground.
Does this require MPBC
With that in mind that Power point will need its own earthing system ie:TTI would say so because the metal frame does represent an extraneous conductive part.
At least now the bonding doesn't have to be 10mm^2
Why?With that in mind that Power point will need its own earthing system ie:TT
What with & where from, its either MPBC or supplementaryWhy?
Just bond the metal structure.
What with & where from, its either MPBC or supplementary
Which is 10mm from a Tncs supply.Neither, the equivalent of MPBC as detailed in 544.1.1
So 6mm^2
Why, what size cable are you taking to the glass house???Which is 10mm from a Tncs supply.
Deemed as a Special location this Power Point now becomes an expensive item.
To comply it will need a TT earthing system for the greenhouse to accommodate MPBC
