Main eq bond

[Tim Watts]

Woopee it's a clamp. It's now in the right place.

But I am impressed I'm getting immeasurably small resistance readings everywhere, including right back to the bathroom basin taps (

[ARW]

Is this ADS or EEBAD:-)?

[Uncle Peter]

What are you doing? Using an old valve radio that needs amazing earths?

[Tim Watts]

The former now isn't it? Pretty sure it was EEBADS when I did my exam.

I'm not big on names, especially when they change just to mean the same thing!

So here goes:

"Live wire, phase, earth bond, bulb, "

That should give a few people apoplexy ;-)

On a serious note -

I am very much against the continual changing of nomenclature for the sake of it which we seem to get a lot of these days...

My water pipe has a main equipotential bond to the main earth terminal. So we might as well say it's earth-bonded. 90% of regular people at least know what that means. The other 10% would shove the wire into a pot plant on the window cill.

"PIR" was easy to say. Does anyone ask for an "EICR"?

I was trying to find a numerous picture of the earth wire thing. But I found this instead:

WTF? I did not know weed could do that (even superstrenghth weed).

Although to be fair, its a bit more than just a name change... with ADS one can forgo most of the supplementary EQ bonding.

nope, not biting ;-)

Indeed they will. The only problem with the nomenclature is that is actually makes understanding the reason for its existence a bit more difficult.

If you can keep the concepts of earthing and EQ bonding separate in your mind, the whole point that they do different things (limit the duration of a shock, vs limit its magnitude), by different mechanisms (opening a CPD with a fault current Vs limit potential difference) is much easier to get a grip on I find.

Yup agreed it does not add much. I suppose the fact that the P was not necessarily actually true is what sank that one.

That last photo in particular looks fairly scary... still I suppose the power was off by then!

:->>>

I agree with that - it's just that folk who work with it will know that anyway - but ordinary folk just get more confused.

We still take are cars for an MOT test even though the MOT was abolished in 1970.

I dare say some people still refer to the electrical regs as IEE

There must be other historical agencys that are still around through common usage.

[Tim Watts]

That was a silly name change IMO - "THe Institute of Electrical Engineers" is a very old name and caries quite some weight.

You have still buy "Type 1 MoT" at builder's merchants.

People will still talk about the "D(H)SS" even though that agency has not existed for over a decade.

Bombay?

[John Rumm]

Main problem I guess was confusion with the IEEE

Potato - yum ;-)

As a member at the time, I was never convinced that it was a good idea.
