Thinking a bit...

[Isetech]

There used to be a reg that stated that a DB cannot be used as a drawbox - That was dropped

I would say not allowed as the main switch will not isolate the DB as per 6.6.1.1

6.6.1.1 Each distribution board shall be controlled by a switch-disconnector
(see 6.9.4). The switch-disconnector shall:
a) be mounted in the distribution board or adjacent to the distribution board in
the same room,
b) in the case of the main or first distribution board of an installation, be
labelled as "main switch",
c) in the case of a sub-distribution board, be labelled as "sub-main switch" "or
main switch" if the board is labelled "sub-board…",

I would assume you havent seen some of the solar essential /non essential DB's being installed, its frightening.

The last one I looked at, had skrewits in the non essential DB, the wall chased to the side, no conduit or protection for the wiring into the back of a surface mounted DB.

The kind of workmanship you can expect from electrical contractors and we wonder why the industry is a joke. By the way this installation had a COC . Can you see anything wrong with it ? A good electrician will spot the problem within a minute, tell us what it is.

Its called a piezo buzzer, I had it connected to a 9 VDC battery. It was a quick way to identify a light from a plug circuit (back when light had a ballast) from a short circuit (if the wires were twisted together) , by the sound it made. It was a long time ago (around 1988/9). People would walk past and see all the wires over the scaffold and ask how I knew where all the cables had to be connected. It is actually really easy. Working on old machines that dont have labels or wiring diagrams, thats are challenge.

This is the sort of DB we find and now they have backup... Try get to those Neutrals and the client wanting the internet on....

Immediate I see the hole on the right once the cover is on.

Second is the yellow and blue cable being used as phase but I'm a single phase DB. As far as I know that is not good. In a 3 phase board it is ok as for phase identification.

A clue... look at the main switch.

[Justloadit]

Yes I noted that there seems to be no Neutral connected.

There are many issues wit this DB, like the wire thickness connected to the yellow etc.

My main concern is the main switch and isolation (safety first).

Stuff like no earth wire on a ceiling fan, or a PVC replacement socket outlet with no earth or a 50 amp breaker is connected to a 1.5 mm wire are as common as DB's that look like this. We all know that it cant be that dangerous, because if it was you wouldn't find it on properties that are 50 years old and have been like that for the past 10 years.

Cannot see a problem with mains.
Isolator. Supply in bottom, load out the top. That's how we were taught to do it on the railway .

Note, the neutral on the top of the main switch.

Oh goodness, didn't see the neutral there, thought the camera angle distorted it.

My phone I cant see the CB ratings but I do now see the yellow cable to the red cable so I assume it's a higher CB hahaha.

Harrowing DB !

Cannot see much there. Photo blurred.
