Hobbyist safety advise when working with AC

(1/4) > >>

Hi,

Just looking for an online course or a good book about safety when working with AC.

As a hobbyist I've been working on quite a few things most of them low voltage DC. But now and then I get myself around something that connects to 220V.

I have read as many articles about safety around AC and they all talk about the same which is fine and I try to follow them all. But I think I could learn more around it.

So... I am looking for a good book or online course with some solid tips on how to stay safe, where the dangers are, security equipment, gear, etc...

Here is a publication by our state's safety enforcement agency:
https://www.dir.ca.gov/dosh/dosh_publications/Electrical_Safety.pdf

There are links to other documents like the formal regulations imposed on industry to help protect their employees.

Note that you will find rules regarding Personal Protective Equipment like gloves, flameproof attire and safety shield - depending on voltage level.

I think you might want to work downstream of a Ground Fault Circuit Interrupter (or local equivalent) and stay away from electrical distribution equipment altogether.

There's a lot involved in staying alive in the electrical business but the biggest factor in getting to retirement is LOTO - Lock Out, Tag Out and the associated testing techniques for proving a circuit is deenergized.

I think you need a better training program than arbitrary YouTube videos...

'Keep one hand in your pocket' and certainly use GFCI. The major thing is avoiding possible current path through you. So it's not a very good idea to poke onto live circuit with both hands simultaneously. Also you need to be very careful using oscilloscope, don't attach it to anything under mains voltage unless you really understand what you are doing.

Search "doe energy safety pdf" on Google.  DOE has a fair amount of information.

The main thing is don't come into contact with energized conductors. Don't poke around inside equipment with power connected unless it is absolutely necessary.
