state of the switch.

With comparatively modern wiring this is true, but when I learned about
electrical installation, in the 60s, the ceiling rose only had two
terminals - the switched wire and the neutral.

F*** knows what the earth wire is used for in a light bulb!!

The metal part of the light bulb base might become live and might be
touched when changing the bulb.

Then it would be sensible to make it out of plactic, using metal is stupid,
and shows how silly the people who draw up electrial sfty regulations are

This is from someone who's done equally stupid things in the past
but was lucky. I assumed turning off a light switch kills the power
to the light fitment & electrocuted myself as a result.

The mistake you made was not checking your, perhaps reasonable assumption
was correct.

Indeed.

Not according to this
http://www.diydoctor.org.uk/projects...d_switches.htm

http://www.diydoctor.org.uk/projects/ceilingroseb2.jpg depicts what I
thought I'd described. Perhaps my description above was poor or at fault.

I don't think you did describe it at all. Anyway that diagram is useful,
however
if I was doing the wiring I would probably not do it like that. I see no
real need
to have permantly live wires in there. The sensible way would be to have the
permantly live wire at the switch, where you would expect to find it!!

but do double check you've done the right thing.

I sure will

Oh wow. Now all you need are the insulation tester and the earth loop
impedance tester. Multimeters definitely don't hack it.

You should listen to the good advice you have been given and get the
work done by somebody who knows what they are doing. You're obviously
not up to the job and could end up killing yourself, killing somebody
else or burning the house down.

Please feel free to dismiss my views, if you wish to continue deluding
yourself.

Which part of this didn't you understand?


Your delusion.


The only people I am likly to kill are those who wind me up to much!!! :OP

The late Mickey Spillane did this sort of thing SO much better.

Not much chance of killing myself, my father rewired houses without
any education or training, and he didn't kill anyone.

It's not my fault you have poor genetic material.

I certaintly hope we are not related.

Thanks. The problem with asking such questions is that the respondant
usually assumes you are familiar with the terms and jargon of the
trade.
Indeed I have a DIY manual which falls into that trap!!
The tell you lots of things you don't what to know and omit the bits
you
do!!
"feed from the lighting circuit, if you take it from the supply between
each light"

I assume a 'feed' is some sort of wire, rather than a ready made meal.

Anyway OK if I open up the ceiling flower I will see lots of wires
I did last time I tried it :O)
So how will that help? You see I am not familliar with household
wiring,
If I was I propably wouldn't be asking would I!!

Anyway as far as I can see there only need to be two wires, a live one
(when switched on), and a return wire.
Anyway I will assume there will be a whole bumch of wires there as that
is what you imply.

"Sleeve your earth cables"???? Sleeve? I don't think I have an earth
cable
that I am aware of? What can all that mean?

"flying power lead"... hmmm....is that something to with aviation, will
I need
to take flying lessons?



Sorry, my mistake, I had assumed this was a tech newsgroup.
Call an electrician.

It's uk.d-i-y

It's uk.tech.digital-tv
or had you forgotten you'd cross-posted?


It is posted to several groups obviously.







OK I will stop this nonsense, What I am perhaps thinking of doing is
taking
a cheapo short (four-way) extention cable (costs about £1-£2) and
taking
off the plug to expose the live earth and neutral wires.
Then I will try to connect them to the existing wires somehow from the
ceiling rose.

Anyway acording to this diagram I wont find the 'always live' wire at
the ceils rose.
So how do I find it?
I guess I need to find the wire from the switch, fortunately I will be
using a bathroom light which has a switch in the ceiling so that should
give
me a good clue. There will be an alway live wire there.
So......... I will be able to get a live and neutral wire at least, not
sure if
there is any earth (only remember seing two wires when I loooked in the
loft.

So I can either forget the earth all togeather or run a wire to a bit
too exposed pipe work. I guess I can test if it is earthed
by touching it with the live wire :O)

That way I will have four power points in the loft and still have a
plug on my amp, which incidently is basically a 'plug' ie it
has no cable.




You won't usually find a neutral at a light switch.
If your lighting circuit is not earthed your wiring is old and probably
needs re-wiring. Do not use it to feed any sockets - it won't be safe
without an earth.

What you have suggested is dangerous and does not comply with current
(or past) Regs.

So what only I will know about it and I am willing to take the
risk:O)

I think you've summed yourself up nicely, and on that note - goodbye.

Goodbye, and don't bother calling me when you need your electrical
system ugraded!! I won't even give you a quote.

the current I will be drawing, as that is neglible the answer is.

For safety's sake, there is rather more to it than that.

If you are concerned about the heat I think are missing the most
obvious danger which is the current being drawn.

The danger is that you will fail to provide suitable protective devices
for the cable rating, or for the size of CPC in the cable you use. If
the cable is too long, there are additional considerations.

We're talking about an aerial amplifier with negligible consumption.

No-one needs more than a neon screwdriver.

(Almost as good as a sonic screwdriver.)

Err... no it's a multimeter! Multi is French for 'many'.

Have you seen a light bulb with a plastic base?

I imagine there could be problems making it strong enough.
