For the electrical panels, you have to purchase, read and know the safety codes to play electrician.
EE's mix up colour codes, don't know the grounding and wire gauges required, Wye/Delta poly-phase power, conduit-fitting sizes and types - there is a lot to learn and mistakes can have consequences.

First I subcontracted out to a panel shop and they looked after it all. You should do this.
Later I did read the electrical codes, looked at existing installations and drew up "electrical" wiring diagrams (they can't read schematic-style). Then after manufacturing, an inspector comes by and approves the panels. Or disapproves. I had one 24VDC rail with ATO car fuses on it and they said "no" to that, because the power supply/step-down transformer could short pri-sec and the fuse would then have to clear mains voltages. OK, no prob just change over to DIN rail 5x20mm fuseholders. But it's a learning that you need 250VAC fuses on a 24VDC rail, as an example.

I do P. Eng stamp electrical panel designs now, but sometimes an electrician installing it will phone to clarify anything or I can still get mixed up with a site having "high-leg Delta" and nobody knew.

I've talked to my managers. We added LVD and VDE to the project requirements, and agreed that an industrial electrical engineer will do the electrical wiring diagram. All good, they were surprisingly receptive to the reasons and didn't put up a fight. Thanks for the advice.

Although, clarification for the people outside the EU:
If you want to sell something in EU, you need to draft a Declaration of Conformity, and state that it confirms to the requirements of CE. The person signing the DoC has the responsibility, to make sure the product is compliant to the harmonized standards, and ultimately the law. While the tasks can be delegated, the responsibility cannot. Which means, that LWYERUP! response is really not appropriate within the EU to this situation.

Or a dermatologist to perform brain surgery. After all, they're both doctors.
