Powerpoint iin the loft?

[Bob Eager]

I am touting no site. Where on earth do you get that idea from?

No, you must be a troll. Or very, very ignorant.

[Roderick Stewart]

We need a new word for the opposite of a polymath - a nullimath perhaps?

Rod.

[charles]

actually it's Latin, but never mind. How many "multimeters" have you met that give out 500v for insulation testing?

In article , Bazzer Smith writes

I^2 x R loss in the cable; that limits the current you may draw according to the method of installation.

[Bob Eager]

Thanks...saves me the trouble of pointing that out.

Ah, but his 'extensive' qualifications in electronics tell him that 1.5 volts is all that is needed!

[Prometheus]

In article , Bazzer Smith writes

It's 240V RMS, which is why you test that insulation is good above its peak value.

I would like to know how you are going to check the resistance between earth and live (earth loop resistance) which has to be on a live circuit because it is a measure of the resistance all the way back to the sub-station, perhaps you will tell us?

[Andy Hall]

It means that the rules have nothing to do with ability and qualification.

[Andy Wade]

In this case I think "troll" is the word you're looking for.

So why do you have a DTTV stick in your set up?

see post "Standard or widescreen monitor" dated/timed 21/07/06 00:54

[Bazzer Smith]

And what do you mean by that exactly? (further translation required, that doesn't say anything meaningful to me)

[Bazzer Smith]

So what?

[Christian McArdle]

You could earth loop with a multimeter. You'd need a high ampage load (an electric heater would be ideal), the multimeter on voltage setting (should probably be 4 sig figs) and a calculator. Unfortunately, you would also need a clue, which might be more difficult to obtain. ;-)

As for insulation testing, I fail to see how this could be done without some sort of high voltage generating set, although if you had access to such a voltage source, the multimeter could be contrived to give you some indicative result.

Christian.

[Bazzer Smith]

It has a 9 volt battery.

I don't need a meter to test insulation or earth.

[Bazzer Smith]

Its a DDTV.

[Paul Herber]

Dumbed Down TV

[Bob Eager]

OK, then, tell us how you would:

a) test insulation to regulations b) test earth loop impedance to regulations

without one.

[Bob Eager]

How appropriate.

[Bazzer Smith]

I test them every day, all my electrics work find and my house has not burnt down yet, what can be more reassuring than that?

[Bob Eager]

You carefully avoid telling us how. Presumably you realise you are not doing it correctly. Or would you like to tell us?

[Mike Henry]

The question was "how", not "how often".
