Morning all, I noticed a weird thing in my gaff the other day. If I wanted to turn off the fuse for the downstairs lights, I have to turn off TWO fuses? What's all that about then? So if 1 and 2 is on: LAMP ON 1 and 2 off: LAMP OFF 1 ONLY OFF: LAMP ON 2 ONLY OFF: LAMP ON Weird that? I haven't checked through the house, only the pendant lamp in the same room as the CU.
