A farm I have done some work for are having an array installed by a third party but I have been asked by the farmer to do some additional work not included in the PV install. At present there is a PME supply into a workshop from which a 25mm 2 core SWA has been buried underground and run to a barn where there will be a submain feeding the inverters for the array which is in a field. An earth strip has been put in the ground at the barn to TT the submain. I have had a discussion with the PV company today as they seem to think it acceptable to put a 100ma RCD upfront in the workshop before the SWA and only have an MCB on the submain protecting the PV inverters. My thoughts were the RCD needs to be on the submain and the SWA doesn't need RCD protections.
Your thoughts please.
