Title: @Dave, Suggestion for fundi friday: Isolation transformers, fuses and worksafety
Post by: con-f-use on October 20, 2013, 03:57:24 pm
So I could surely use some basics on workplace safety. Also I'd like to understand why and when each of the specific precautions is need. So far I just used common sense and my general knowledge from my few labs in college. I never got hurt and want to keep it that way. I think that most hobbyists come to the point where the build or troubleshoot main voltage devices. I surely tinkered with the lighting and mains wiring around my house. Also I built and troubleshooted a few devices pored by the mains. If I do the troubleshooting part more often I think I'll need an isolation transformer. Also I'd like a breaker circuit and an extra fast fuse for my bench.

But I find it very difficult to wrap my head around it in the limited time I have for my hobby and still get stuff done. Also it's not the easiest of tasks to separate the overkill from the really useful advise. So I'd be thankful for a good basic introduction to workplace safety focused on mains voltages and the electronic hobbyist.

If you, Dave, are not interested in doing such a video, I'd be happy for someone to point me towards good tutorials and equipment to have. I still feel a bit lost on the topic.
Thanks for your attention.

You may want to try EEVBlog #279 which touches on that kind of issue, even if it's not exactly what you're asking for.

Thanks, I saw that and it was very helpful. But things like RCDs, isolation transformers emergency switches, spike protection and general wiring is dearly missed.

The subject is important enough and the potential for saving one person from a BAD day -- or worse.

If you find something you think is useful re. safety, yes, I would be interested to hear it.

By the way, do you guys know a good place in the EU (preferably Germany and Austria) where to order a modular power plug system for a small lab? I was thinking something like Ehmann Modular Series (http://www.voelkner.de/categories/1109_6_10_9581/Haus-Garten-Freizeit/Elektromaterial/Verlaengerungskabel-Mehrfachstecker/Steckdosenleisten-Modulsystem.html). I need RCD, over current and voltage protection and noise filtering. The Ehmann RCD module there is somewhat pricy thinking I could by an RCD+Fuse for about 4,-€ and build my own strip of power plugs.

Safety is very important in workplace, you so not want to unleash the magic smoke from the house wiring. I have an ABB C6A circuit breaker just for plug-in soldering iron and 8W T5 light in my own built suitcase workbench.

fundi friday sounds like some kind of scary "devout" christian religious festival   :palm:
