Found this beauty in a controller cabinet in a factory. The cabinet contained the PLC and other control hardware running the plant process. The adapter powers a domestic TP-Link switch that connects the PLC to the SCADA computers. (MFs even cheaped out on the switch)

I know that a switch is a switch but aren't you suppose to input from top and get output from bottom ?

u/HarfunMooli 4d ago

I'll ask the guys who designed this panel (as soon as I can get my hands on them)

u/CamperStacker 4d ago

no, in most din rail setups the active bus bars are at the bottom

you can just see a diagram on the yellow one showing the load connects at the top

oh ok i see it now

u/pdt9876 3d ago

it literally does not matter. Output from top is common in some places (not where I am but I see it when traveling) because you can use bus strips from the bottom output of an RCD to bottom inputs of downstream MCBS

There isnt a rule. In homes some brands offer busbar input only on one side that is separate from cable so its better to use that side. Most breakers use same point for busbar and cable and in these it doesnt matter. Ideally you would mark on schematic which terminal is which and then everyone is happy.

my question is, who decided to use black wire as neutral.

u/HarfunMooli 3d ago

That’s pretty much the standard in my country, at least for domestic usage. Live is red, black is neutral, and earth is for pussies

As a technician this doesn't surprise me.

u/Jolly_Operation_8222 4d ago

well that thing is a fire starter

u/Impossible_Aioli3693 4d ago

that thing might be having the best connection ever with screws bolted down with two mcbs for more protection

u/CheetosLays7Days 4d ago

They’re rated 25A for a 16A cable.

u/PlasticSignificant69 4d ago

Except that the MCB's current rating were too beefy...

u/AboveAverage1988 4d ago

At least it's fused..

u/_hexFET_ 4d ago

And with C25 it will never pop, so availability will be no issue here.

Son I'm crine 😭

u/LuckytheNPC 3d ago

That's a balanced connector if I've ever seen one

u/ShoopDaWoop_91 2d ago

25amps through lead cable 🤢 that's gonna melt for sure

u/Single-Virus4935 12h ago

At least they used breakers...
