What would people suggest as a cheap way to afford a bit of protection to
some low votage (24v) electrical cable running between a shed and a pond
pump?

Basically we're talking protection from the elements and from
rodents/anything else that might nibble at it..

Hosepipe seems the obvious choice, but the local Focus and builders
merchants don't seem to have anything other than "normal" garden hose,
which isn't wide enough..

Personally I've just buried mine in the ground and covered with
bricks/slates to stop me putting a spade through it. Weather shouldn't be a
problem but if you do want to sheath it in something I would have thought
that standard hosepipe would stop most things chewing through it. For
something more robust you could try 15mm plastic plumbing pipe.

I used some garden hosepipe. If ever I need to put thicker wire in it will
be simple.

Hose pipe seem to work for me. Have you thought about the blue pipe that is
used for running water outside it has a larger diameter than std green hose.

The chap that had my house before me laid a mains cable to the garage about
a foot down and laid a water pipe over the top. Whether he did it
intentionally or not I don't know, but when my son-in-law tried to sink a
pond in there he got very wet before he got to the cable.

I'd advise against that as there is a standard for underground

Bloody hell.

For my propagator (which is on pond cable) I bought the actual rigid cable
conduit and couplers. Can't remember how much for though, I'm afraid.
(Although the couplers were 10 or 20 p each). This was for laying under
slabs however.

Are you sure you're using the right cable here? Unless it came with the pump
it sounds like you might not be. Even armoured cable which takes more than
mains power is not always as thick as that! Mains-voltage low-ampage pond
cable is about 6mm thick (if that makes any sense).

Use proper plastic conduit with sealed joins! Only way to be sure!

Bloody hell.

Er, why? 11kV under ground is *very* common. I think there are parts
of the supergrid under ground as well, 250kV. If not some of the 125kV
stuff will be, probably oil encased and the oil circulated to provide
cooling.

Mains-voltage low-ampage pond cable is about 6mm thick (if that
makes any sense).

OP said 24v ie low voltage and thus high amperage for the same power.
High amps means lots of copper, means bigger cable.

Except that a pump will be very low power.

Not many amps!

The query was for low voltage cable.

So you should use black conduit.

Possibly Dave, Warick is questioning your definition of the voltages - as
I also did. The ususal bands are (IIRC!):

LV is usually defined as 200 - 600V (1 phase) or 400 - 1000V (3 phase).
MV is 1kV - 11kV - 33kV(3phase)
HV is 33kV and higher (up to 400kV in this country)

There is also ELV and SELV - definitions of which you should look up in
BS7676 (The IEE Wiring Regs) - these are extra low voltages.

Plastic conduit is about £1.50 for 3 metres from B & Q.
