I'm going to re-phrase some points raised by another. I know, some topics can inspire passion - but here we do try to use complete sentences, and words of more than one syllable
Maintenance electrical work is a world of its' own. The first rule is : Safety. Protect yourself. The company is required to provide you with the means to lock out equipment while you work on it. Use it.
Rule #2 is: Stick to your guns. If it needs fixing, fix it. It matters not how upset the production folks might get. It's just not worth it to cut corners, and have a greater disaster happen. Should such a disaster happen, you can be sure the very ones egging you on will insist they did otherwise.
Rule #3 is: Get educated. The company should provide you with some training; seek out additional training on your own. As a maintenance electrician, it's not enough to know your trade. You also need to understand the processes you need to control.
While all apprentice electricians get some training in motors, and their controls, it's well worth it to take some courses at your local college. It's a bit different from your usual 3-way switches
Keep in mind that industrial sites have an entirely different sort of hazards than construction sites. You'll be exposed to mechanical, hydraulic, pneumatic, temperature, and electrical risks entirely different than what you see in construction.
Some things require special training .... if they point you to the high voltage gear, and expect you to 'figure it out' without first training and equipping you, run like mad from that place! Know your limits.
