Domestic remodel - Sanity check on a couple of things

"134.1.1 - ....etc. The installation of electrical equipment shall take account of the manufacturers instructions"

It's on a 32A breaker

There is a 150mm safety zone created at the angles of two faces of the wall no? Therefore it is within a safety zone where the window is, but that zone stops 150mm below the window sill... at least that's my take on it.

Because most people (except electricians) have no idea of safe zones I tend to try and limit the use to the most obvious locations where possible. Since the zone description is 150mm from the angle of two adjacent walls I do not think that this applies for a penetration through a wall such as a window frame.
You can also think that is someone is hacking out the window to change it they may well hit a cable; however a similar problem occurs with coving on the 150mm from the ceiling zone.

Must admit, I'd never thought of a window opening as usable as a safe zone. Would you also regard a door opening in the same way?

I guess it's one of those issues that's open to interpretation. I'm planning on adding an outlet at the bottom of the wall just in case and I'm annotating plans for the customer showing where the cable runs are along with junction boxes. Aside from a blob of dot'n'dab, that cable's of the only one that causes me concern in terms of location wrt the zones.

Think the whole zone thing is a daft idea, only sparks know about it. Repaired loads of 'drilled into' cables directly above faceplates, nearly done it myself once

Incidentally, do plumbers have such zones?

Came across this doing kitchen refurb'. The gas pipe fed an unused gas outlet for kitchen cooker, which wasn't directly below it;



The three holes were for the old wall unit brackets, luckily the drill bit somehow managed to miss the pipe.

Edit, the cut oblong hole I did, so we weren't attempt the same thing.

I certainly agree with the above,it would not be so daft if the zone secret wasn't limited to the very people who install the cables and also the knowledge expanded,not only to include other trades, but rammed down the throats of the designers of kitchens,these seem to have no perception of the absolute chaos their efforts can cause

Gotta agree with that. Loads of time I go to quote for the kitchen electrics, and the designer has moved the electric cooker to the other side of the kitchen, and CU has no RCD for that circuit.
