At my previous place there were many pallet machines and I was trained as an apprentice on how to fault find inside them. Was always fun to see what temporary repairs were still in there 10 years later after getting frustrated that the electric diagrams were now not conforming to what exists. A top tip I would give is when you have an old electrical cabinet with no documentation, draw your circuit on a piece of paper as you go so you don't have to do mental gymnastics remembering what controls what. If it is equipment you will be working on for a long time, label what each contactor and relay does on the cable conduit.

Trunking lids off, some totally missing, cables hanging like a spider's web. Multicores coming into a terminal rail which connects to another Multicores which then runs up the trunking, across the top, then down into a set of terminals further up the same rail. Did the installer cut their original cables short? 😉

I have spotted a couple of non compliances against BS 60204. No continuity of bonding from MET to the door. How it is done in this panel is non compliance. Also identification of components should not be placed on the trunking but adjacent to or on a component itself.

Was an commercial electrician and seldom had schematics to help troubleshoot. Hardest part was troubleshooting intermittent problems. Had one huge panel that a single 20 amp 120 volt transformer with only a single 20 amp fuse feed over 20 remote solenoids, 12 motor starters, lights and probably 30 micro switches. At least once a day it would blow 20 amp fuse. Boss finally allowed me to install about a dozen in line fuse holders to direct us to what section had a intermittent short.

I used to work for a multinational company, I was a shift mechanical engineer who worked alongside an electrician and support worker in the facilities dept. One day I had a new electrician working on shift and we has a problem - an AHU had tripped, and it was critical to production. We attended the plant room and I opened up the panel, the wiring practically fell out to meet us, there were zero drawings available. I reached inside and reset an overload on a 3 phase contractor, something I’d done many times. Later the electrician confided to me he’d sh1t himself when I opened the panel door 😂😂😂 The panels ( of which we had hundreds ) were typical of the factory, you learn to appreciate a new neatly fitted panel with a drawing

Electrician is an all encompassing term, there are at least three separate trades in the one trade. You have your domestic sparks, commercial installers and maintenance electricians. The only common factor is it makes you jump if you get hold of it 🤣🤣. We all do a-bit of each others trade but it's horses for courses in reality.

That's a baby control panel, I've worked on control panels that would dwaf that by a factor of 30 plus, there a nightmare when nothing is s numbered and they been repaired number of times over the years and you can guarantee the wiring diagrams are well out of date because of the old components weren't available and they had to use a modern equivalent of new equipment been installed and they rewired the panel to make it work with the new machinery.

@pn8902 Жыл бұрын

You have no idea what youre talking about, Label the component what?? Call it Relay 1, then what? which cable is going to the load, which is the supply? They will all be brown/blue. Basic electricians cant have an opinion on how things are done because all they know is "put brown here and blue there and it will work". Control panels need a lot more knowledge. Dont mean to offend any electricians but that's just how it is, and if you dont feel like that then you're more than a basic electrician so you're good :)
