Hello all, I have been asked to do a eicr on a property, as the client has asked to rectify any issues as I go along, I have come across a supply to some storage heaters running off a oldb3036 consumer unit. It is running off a 24 hour supply ie 4 terminal meter but within it has contactors. I need to change this board but how do I approach it and where do I start I ve posted some pics the contactors are within the consumer unit. Is there a consumer unit to replace it or something else I can purchase
