Overloads?

Is this the overloads

I can see a soft start, but those particular models don't provide thermal protection.

I would suggest the builder of this panel is clued up about how to design controls and circuits but is lacking in knowledge of the BS60204 as they have cherry picked certain reg's and totally ignored others, also I would suggest a PLC would have simplified this set-up greatly.

Programmable relay like a LOGO sure, a full on PLC would be hugely overkill for this.

Looking at the age of the components would suggest it pre dates things like the LOGO, weren't as cheep or common as they are now.

We still design panels like this, simply at the clients request as the know their maintenance staff could maintain it if it broke down.

Do vsd's take in single phase and spit out 3ph

Vsds can be single phase in or 3 phase in. All output 3 phase. They output the same voltage as they are inputted (no doubt there will be exceptions but none that I have seen) ie 230v in single phase = 230v 3 phase out.
400v 3 phase in = 400v 3 phase out.

400v 3 phase in = 400v 3 phase out.

You can get single phase output for 1ph motors, they are not just for 3ph motors.
You can get step up drives e.g. 110v in to 220v out but these are limited to the very low HP range.

Not as common I'll give you that but it does mean what you have put is incorrect :hair:

Panel obviously does not meet the requirements of the Machinery, nor Low Voltage Directives, again.
This is becoming a very common theme these days, why I wonder is it that there seems to be an increasing number of panel & machine builders who can't design a panel that complies with statute law?

I think the short answer is probably the same reason there are Cowboys in every trade, because nobody has stopped them and people keep paying them.

Well roll on FFI then AFAIAC.

It may not be compliant with the machine regs but I regularly come across panels a lot worse than that. Just out of interest what's the component that's mounted at the front right of the base of the enclosure?

It's hard to tell but I be guessing at a panel heater to stop condensation :hair:

Fees For Intervention.

Levied on companies that have a material breach of statute law.

Hopefully these will start to hit home and companies will begin to learn that they need to comply, because not only will they get a PN or an IN, but they will get FFI too, that will cost them out of their bottom line, and they can't insure against enforcement.
It is I think £129/hour currently.

I've seen worse like this work of Art.

I much prefer it when timers are mounted half in the slotted trunking

That's not bad for an old panel.
I've seen & worked on MUCH worse.
However, the statute law is there and it controls new panels.
Hopefully the legislators will soon catch up with the rogue panel builders and buyers and put them out of business, so that those that do it right are competing on a level playing field.
