In my case, it was from not realizing that the lightning strike had caused a flashover in a 0-1000VDC transducer, over to the 0-1mA side. The analog point was elevated to 600 VDC.

Ouch!! That would hurt.

Let me ask a related question here. When changing out receptacles or switches around our own homes, how many of us bother to turn off the circuit(s)?

I'll admit that I generally don't, unless I see that the wiring inside the box is unusually ugly or dificult to work with.


There are 10 types of people. Those who know binary, and those who don't.

I'd like to a very real sense, we DON'T get shocked- at least, not as often as you might expect.
Look at the NIOSH or OSHA statistics....the vast majority of electrical injuries happen to folks who had no business whatever working on the electric! For that matter, most of them also involve "safe" 120v, 20 amp circuits, or smaller.

When it comes to our trade, sure, complacency plays a part. So does "bare minimum code compliant work."
Panel directories often have lables that are of limited use, being blank, out of date, un-readable, or vague. There is often enough electronic noise in the panel to severely impair the use of any "toner" I've used. Heck, sometimes you can't even be sure which pane the circuit is in!
Then there is the matter of your shutting off the power causing other unsafe conditions. Like, say, plunging the entire room into darkness. Sure, YOU might have a flashlight....but the secretaries will walk into your ladder on the way to the coffeepot!
Add multiple circuits in the box, and shared neutrals to the mix... and you learn to work as if everything really is "live"..even after we've turned it off.

I don't mean to sound callous...but when you choose your trade, you choose your injuries. A fireman gets burned, a butcher get cut...and an electrician gets zapped, or falls off a ladder. Recognise that..and work to improve the odds!

I got a little "buzz" the other day that shocked me. I was on a (Gorilla) fiberglass ladder and not really touching anything when I bumped a wire in an octagon box that bit me. It didn't pull enough current to trip a GFCI (tested OK later) but it got my attention. I am still not sure of the fault path but it was real.

Never leave a pager or cell phone on vibe when working hot.They tend to go off the minute you are tying something in.The real question is who uses mats gloves insulated tools etc.I know my allen's have a custom taped job on them.I for one can't work in gloves so I just use a mat when I need too and use the leathers.

Yep Yep Yep I get shocked working on light circuits more than anything.Tying in breakers wires etc never had a problem.Of course I am new to the trade 18yrs ago.I do have enough sense to eye protection though.I just don't like the rubbers.I know I am not alone either.I will wear them when I feel it is absolutely necessary.Anymore with the workermens comp insurance lawyers etc.I almost de-energize a lot more than ever before.Of course waitng for the power company to remove a meter or cut loose an overhead drop I tend to just do it.Time is money right.
