Do "volt sticks" work on armoured cable?
 

Following an episode of depriving three flats of mains power for 8 hours I
thought I'd buy some of those cheap volt sticks mentioned here recently.

Seem to work fine on ordinary cable but not on my armoured incomer. I
suppose I shouldn't be surprised by this but clearly they're not gonna stop
me drilling into another armoured cable. ;-)

Out of interest, would the type of armour make a difference (say steel
versus copper)?

They aren't meant to be cable detectors. Surely a proper detector would
be better?

My Kewstick Uno detects normal flex as live from any angle/orientation,
it detects arctic flex as live *unless* you have the tip directly over
the earth core with the tool perpendicular to the cable, but it will
*not* detect any live indication whatsoever from 2.5mm^2 SWA.

Never heard of copper armour. I'm not too surprised that they don't
detect live SWA cable, especially at any distance. However a good "metal
detector" ought to work, also consider a rare earth magnet which (I
guess) might pick it up through up to a centimetre of plaster, but
probably not much further.

I wasn't intending using it as a cable detector. My folly was to drill
(deliberately) into an old copper pipe to determine whether it was gas or
water (having turned off both first) prior to removing the "pipe". I forgot
the third option. ;-)

Copper sheathed mineral insulated cable is fairly common, but I've never
seen any big enough to be mistaken for a gas or water pipe. Still I
suppose this was supplying 240 or 300 amps.

Certainly providing mechanical protection, but I wouldn't call it
"armoured".

Mine uses capacitive pickup, so any earthed metal stops the signal.

8 hours is a long time.

It was probably longer. Certainly long enough for the electric company to
rig up a temporary supply.

Of course if the main fuse hadn't been hidden behind a plasterboard
partition behind a radiator they might have found it a bit quicker. ;-)

The will not pick up the field through metal of any type. That includes
metal screening, armouring, conduit and etc..

To help prevent your drilling an hidden amoured cable, metal pipe or
similar buried in a wall, a metal detector works well.

I'd not think copper was much goosed for armouring a cable though.

Yes, one should be able to use a metal detector to find something in a wall?

Never heard of copper armour.

Also it's used with cables which don't have balanced feed/return current
such as 11kV singles, although it's really there to generate an earth
leakage if the cable is damaged, and is much thinner than steel armour
wires. Hopefully you don't have any concealed 11kV wires in the wall!

Was it an ordinary coppr pipe, or was it a mineral insulated cable
full of compressed white magnesium oxide power as the insulator)?

I do recall a Mr. Terry P mentioning standing outside in a thunderstorm in
wet copper armour shouting "All Gods are *******s!" but this probably does
not relate to your issue :-)

The latter, although to a fool it looked awfully like an old copper pipe.

I have never (until now) heard of the outer conductor in a concentric
cable being called armour. To my mind it is just a concentric
conductor.

Yes. Point noted and I was wrong with what I said.

It was more to say to newshound (and other posters) that there are cables
with copper not steel "outers" that look like SWA. The clue being in the use
of the letters SWA.
