[QUOTE="GD16, post: 515545, member: 33818"] Ignore my last comment I don't need to worry about increasing the the CSA of the earth conductor, (its 4mm 3 core SWA currently) as there are no extraneous parts in the shed so no need to worry about the combined bonding and CPC size requirement. Perhaps your right TT system is a bit of an over kill in this situation but I wasn't sure if its better to try to protect from a possible loss of neutral especially as there are metal light switches currently installed in the shed. I see some have suggested just bringing the CPC to the shed and also using an earth rod to give additional protection in that eventuality however rare. It seems there is a lot of different opinions on this. [ATTACH]11539._xfImport[/ATTACH] [/QUOTE]
