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 are 25mm2. Now the supply to the horticultural green house is done in a 16mm2 4 core swa cable the armouring being the earth. The green house is situated about 200m from the origin( transformer).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 ( 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.
Any advice would be greatly appreciated if you can understand my ramblings
