I went to add a double socket spur into my upstairs ring main earlier and have just discovered I have 1 switch in the cu for 1 double socket downstairs (no idea why), and then the hob/cooker is on another. But everything else is on the 1 32A 2.5mm ring main! Thats 12 single sockets and 8 doubles, is this ok? It hasn't tripped once in 2.5 years of heavy use at certain times!
