Main Breaker box Wiring

[BillB123]

Hello Gentlemen
Great Forum!
Newbie to this place, not sure if am posting my question in the right section.
I am attaching a pic showing wiring to the 220-240V main panel, my question
is this the correct way of making these connections?
I do feel something is missing here as I am confused with these
colors, as well as why one wire goes into the breakers. why no white wires?
also, I see 5 green wires into 5 breakers but only 1 green wire grounded.
Thank you all

that is a three phase board. Why is their greens tails going in those fuses?

That is the most astonishingly bad example of cable colours being apparently applied at random! Are you from Saudi Arabia as the flag indicated?

The main feed looks like the old UK colours (red/yellow/blue for phase L1/L2/L3 of a three phase supply) in which case the black to lower-right strip would be neutral.

Normally one would hope for an earth as well (green pre-1977 UK, green/yellow striped after), but the strip lower left (I'm guessing is bonded to the metal chassis) seems very bare!

Otherwise the circuits wired in to the breakers/fuses (can't really tell) appear to be randomly chosen!

Buzzlightyear thank you for the feedback, much appreciated; my thanks go to PC1966 as well, and yes I am an expat working in Saudi Arabia. Where I come from it is white, black, and bare ground, red on 3 ways. I heard a little sound coming out of this box so I'd decided to take a look at it ...this is what I have found. Not surprised at all since most if not all "so-called electricians" here are not properly licensed and I am being polite to them!

I would advise extreme care in a place like that!

From a very limited experience of wiring in Egypt:

• you cannot depend on the cable colour to tell you its status (live or not)
• switches are sometime put in the neutral path (not live, as required here)
• few or no earths at all

The very dry climate helps reduce accidents a little

You should always assume electricity is deadly, and properly test that a system is dead before working on it (proper voltage tester, not a neon screwdriver or non-contact tester) in all places, but this just add a whole extra degree of danger on top of the usual.

I assume they are all power circuits so would be interesting to see some of the socket outlet colours/connections.

Colours for finals clearly a random selection, lol
Not sure from pic if there are any CPCs at all.
Recommend several fire extinguishers to hand in the building....

PC1966: I am way over my head with safety. In fact, I have not heard this word here for a long time, I missed it.


Westword10 thanks and there you go:
Note: these boxes in the bathroom with a shower, the sink is located no more than 16" from these 3 boxes, so much for GFIs but again as PC1966 said:
they believe the very dry climate helps reduce [bathrooms] accidents a little

This is the wiring on the left side switch: blue wire is turning black? cooked? yeah

 

[westward10]

What is behind the socket as there are no earths at the switch but it may not need one.

clos st thing I can find to our bs7671 for Saudi Arabia is IEC 60304 and this document;

Edit; It appear the Saudi version of Bs7671/IEC60304 is SBC401; SBC_2018 - https://www.sbc.gov.sa/En/Feedback/Pages/SBC_2018.aspx
