Following on from my previous entry regarding junction boxes. I just thought I'd share with you a photo of a fairly normal installation found in Brighton and Hove (and I'm sure elsewhere) that has (over the years) been heavily modified and extended. As you can see, this often leads to many junction boxes being tacked on to the existing wiring. This is far from ideal, but is unfortunately extremely common place, and these are lurking under many a floorboard! Interestingly, this installation even includes a recent addition (the grey wiring) that has been modified in the last 10 years.
