Hi i was looking for some technical advice please.
I have currently been asked to do work in a agricultural college to put a socket in a horticultural green house. The main college is supplied by a Scottish power transformer it is a TNS system,so the main bonding conductors need to be 25mm2 due to the size of the incomers. Now the supply to the horticultural green house is done in a 16mm2 4 core swa cable the armouring being the earth. It has a gas supply and the large aluminium frame is in the concrete.The question i am asking am i right in thinking no alterations or additions should take place as the main bonding is not of an adequate size as they are done in 10mm2 ( ie that the bonding conductor should be of 25mm or greater due to the length) .Due to the supply cable feeding the horticultural green house having an inadequate size.
