Ditto shame no slotted trunking but very nice anyway and I've seen a lot worse
That's taking it a little too far, to be honest...

Remember though if you ate building a machine to be used in a business undertaking, then this is legally putting the machine onto the market, thus it must comply with any and all regulations that apply to bought in machines.
I doubt that this panel would tbh, and not the apprentices fault really.
However the law still applies, and it's panel does not meet the requirements of the statute law, or harmonised standards for compliance with the relevant new approach directives.
Firstly, thanks for showing your work.
Secondly, holes are rightfully being blown into this example!
You have stated you are not a panel building company... who has verified your circuit design in relation to the Press risk assessment?
Presses... are they covered by special regulations?
Your 400vac (assumed as no signs) feed wiring is in black... your +24vdc is in black... your switched neutral is in blue... your PSU supply (230vac) is in blue... your -24vdc is in blue... You say you want to raise standards... DO IT BY ADHERING TO CURRENT STANDARDS.
Is it an earthed ELV control circuit?
Your lack of wire numbers may be omitted assuming your schematics are spot-on! I take it you have schematics... if so are they computer drafted?
What are you powering with that PSU? It's huge. What is it rated at? 10 or 20A?
These days anything over four relays should be replaced with a programmable logic block or smart relay... thats not to say it must be.
Safety relay? To what safety category have you installed to? Are external monitoring contacts used as part of resetting the light barrier?
What tells you that the motor DOL has tripped? If it alerts the operator then it prevents him fiddling when he can't start the m/c.
Are we to assume all your field wiring leaves from the top of the panel?
I'm not keen on your control wiring passing so close over the supply of the isolator.
Your last sentence... they should not be left wanting!
Please show a photo of your schematics.

Now hang on I wasn't having a go just saying the only thing to stick out obvious was the panel trunking otherwise it's a nice jobThat's taking it a little too far, to be honest...
