German flag?

Easy tiger German flag is black/red/gold. Do you mean Belgian?

Erm, yeah

The EAWR does not outright allow for live testing - the person conducting the work must be competent or under the supervision of someone who is.

The EAWR covers work on all electrical systems. It doesn't matter what the voltage is - the EAWR covers the range from a watch battery up to the supergrid voltage.
I spent quite a lot of time working on battery systems, that was classed as working live - and it would bite if you put your hands across 400v worth of cells! It could also explode if you cross the poles. Another example of work covered by Regulation 14.
You can apply the EAWR to any activity at work involving electricity - not always the most obvious ones.

I have already explained my reasoning.

No, you've said that you have a definition of work which excludes testing.

But you are only interested in semantic games revolving around the word 'work'

No, not games, but to do with semantics, as in "what do you mean?"

and asking me for non existant EAWR definitions of 'work activity'.

If the law does not define "work activity" then you cannot exclude some kinds of work and say the law does not apply to them because they aren't work.

I will concede that the EAWR does allow for live testing, but I would always argue that testing is totally different from working on live equipment.

Testing is an example of a work activity on or near live conductors where it is unreasonable in all the circumstances for it to be dead and reasonable in all the circumstances for it to be done it while it is live.

And anyone who thinks that testing for live or using a LI tester is the same as working on live systems is kidding themselves. And more importantly setting themselves up for a serious accident.

Nobody has claimed that all live working is the same.

I know all this does'nt suit your utopian beliefs that all things must be black or white, but ask yourself, am I bovvered.

And all this because you said "Live working is illegal, except for specialist live jointers" and "Live working is specifically forbidden by 'the electricty at work regulations'" and "if you are doing live working you are almost certainly acting illegally. Unless you work and have been specifically trained by a dno to work on their systems", refused to accept that you were wrong, treated every request to explain what you meant or to look at what the EAWR actually said as "semantic games" and tried to wriggle out of the hole you were in by saying that testing was not a work activity.

Indeed, some people seem to have the mistaken idea that because it's "only" a battery there's no danger, especially at low voltages. The 50V battery banks used in telephone exchanges, for example, or even the 28V banks we had for some equipment at BT, might not offer too much risk in terms of shock potential, but we're talking about batteries with a very high ampere-hour capacity and internal resistances low enough to deliver a short-circuit current in the thousands of amps range. Short the busbars out with a wrench, or a metal bracelet on your wrist, and that wrench or bracelet will very soon become a red-hot piece of molten metal.

And with luck you might get splashed with hot acid!

Where I did my appenticeship, they had 'portable' welding sets.
this basically comprised a large trolley (about the same size and wheel base as a mini) laden with batteries. Those babies could melt some metal, no probs

about the acid-splash bit - im not going to tell you my little story entitled 'what happens when you replace 1 of the batteries an a crane 24v system in the dark for the first time'

Yep, acid splashed all over you, a molten bracelet burning into your wrist..... It's just a never-ending round of fun!

I know its a dated thread but I did take this pic to post here and just found it while clearing of my memory stick.
