    Switch Placing

    Hi Chaps, Quick and simple question I'm sure for most of you: Is there a minimum distance from a door frame for a light switch? Was measuring up today and have marked them up 150mm from the doors.. Purely with safe zones in mind (I know this isn't a safe zone) Thanks

    Position of rails/clamps

    Do you think the where the panels are clamped is ok, They are Suntech so ok clamped on the short side, but I refer to the overhang, as you can see there is some slight movement between the 2 rows on each array.

    Incommer position on CU's

    Does anyone else move the incomer on domestic Cu's to suit tail position? Every Wylex I've ever used is on the right hand side. Thought the busbars were also designed to link line to the first protective device as they are next to each other
