My aluminium greenhouse is set on a steel base in the ground. It has a mk masterseal socket supplied by 2.5mm 3 core swa taken from a 13 amp fused spur from the kitchen ring final in the house a few meters away. It is used for one propagator.
Reading other posts, and excuse my lack of knowledge of the terms, I see I may need to earth the greenhouse frame as it is an extraneous conductive part , in contact with the ground? Furthermore, I may also need a similar arrangement for my aluminium staging, which is portable? Is this incase it accidentally becomes live?
If so, would this be done by a local earth rod, or need to go back to the CU? If so, could the wire armour be used for this, or I see from other posts a 10mm2 earth wire may be needed?
I am DIY and have no intention of doing this type of work but just wanted to get an understanding before getting a spark in.
Supply is TN-C-S.
