AFDD !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[Toneyz]

Sorry I don't know how to post up a youtube link but have a look at the John Ward one part 2 on AFDD's worth a watch.

Nice vid.
Are you sure he tested it correctly to standards IEC 62606 and 60898-1?
I showed this vid to one of the guys at work. We couldn't find the spec for the Eton on but we looked at a ABB one.
He was testing on a 40W load. That's 0.17A on a 16A device.
The ABB graph doesn't even go down that far. It just goes to 0.1 (which is 1.6A. 10th of 16A) and it is looking for an ark of 1 second at about 2.5A, so could be up to 10 seconds for 0.17A assuming the graph continues up.

Yes but I think he was trying to say that the small spark he WAS creating might be enough to start a fire. Might.......obviously the more juice you have the more likely you are going to get a decent spark, but these days you often are not going to be using much, especially on lighting circuits. So is it worth it?

I understand where you are coming from mate, but it looks like the people who wrote the standards for these devices don't think that these small sparks are significant enough to cause a fire, as if they did then the AFDD's would be designed to detect them.

Saw it earlier. Makes you wonder if they are any good?
Its the downside to letting commercial interests get on the jpel/64 and influence regs. The companies that make them have seen £ signs galore with these.

This just reinforces my original thoughts....what a pile of carp.
It might have been an idea to have increased the loads whilst monitoring the temperature of the point of arc.

It's a good idea but ill thought out and too rushed thorough, as well as being far too expensive.
At least the design of an RCD does not require any electronics and works on basic science.

You can basically ignore the tests done on the vid as they are flawed.
It's disappointing really, as when you look at it, it looks like John Ward did not actually read the spec before doing the test. If he did then he knew his test would never trip the AFDD.

Good video, embarrassing for Eaton.

I watched this last night, the comments someone had made under the video are very valid, rather than messing around with a 40W lamp for half an hour, he should have tried it with a kettle or something else that would draw more current.

What do you mean Spoon? I missed something.

Read my post #15 mate.

Not really mate. Read my post #15.

Thanks Spoon message to me read the entire post before asking a question, the answer is more than likely already there.

No worries mate.

I won't be recommending AFDDs to anyone i work for . Stinks of corporate back handers .
I have devised a way of testing them though ...

It involves a kettle plugged into a socket and me at another socket arcing the live wires whilst doing a headstand on the 18th Edition

On the plus side, they have a nice yellow and green light
