Distributors and Isolators

The zappy stuff comes in, through a hole in the wall, into a Big Black Box with a sticker on the side, thoughtfully provided by Yorkshire Electricity, indicating that fiddling with this box in any way could result in extreme death.

It then goes up through thick serious red wires into a baffling array of isolators and distribution boxes.

These boxes feed other boxes dotted about the works, there are another eleven of them. Isolator 2 feeds Distribution Box 2, so far so good, but then things hot up: Distribution Box 2 feeds Isolators 4, 5, 6, 8, 9 & 10. What’s happened to Isolator 7 I’ve yet to discover.

All these boxes are fed by steel wrapped, four core, 3-phase, grown-up DO NOT TOUCH wiring. But assuming Isolator 2 would live up to it’s name, I shut it off and proceeded to disconnect some of the black electric spaghetti currently festooning the beams.

Oh yes, it's all lively stuff down at the Printworks.
