And another question ... If the isolator between the REC's meter and the CU were made to be a change-over type it would also be a safe way of connecting a generator to the CU - but where to buy one from? The local CEF just quoted £165 for a 100A DPCO surface mount switch - seems a bit OTT. Any suggestions on where can I get one for a more reasonable price, surface mount or DIN rail mount.
