djk, thanks for that realy comprehensive drscription, I endorse the irish way of thinking with the socket on the cooker outlet. Am I right in thinking that you provide fusing ither side of he meter and then final circuit protection. Thats somthing thats seldom done in the UK other than perhaps TT system. Most times here its straight out of the meter into an isolator that integrated into the consumer unit.Then straight onto cpd's via common rail busbar.
