Someone I know has armoured cable running in metal conduit from their house to an outbuilding. As the outbuilding is collapsing and the wiring in it damaged the electrician that did an EICR a few years ago disconnected the cable from its dedicated MCB at the CU.

The outbuilding is now rebuilt.

The armoured cable looks in good condition but ...

1 - The metal conduit (old fashioned steel galvanised type conduit) is corroded so probably needs replacing.

2 - The conduit is screwed to buildings where it can be BUT for the run up the garden the steel conduit is tacked at ground level to the side of a concrete path at or just below ground level. The BS guidance says such conduit can be attached to permanent structures. Is a concrete path deemed a permanent structure? I would say (and hope) it is. It seems adequate to me.

Regarding point 2, any thoughts?

Many thanks

It's unusual for an armoured cable to be run in a metal conduit, are you sure it's an armoured cable? The full length of the run?

Yes it is.

I think the conduit was probablyt used to avoid the need to bury the cable down at a reasonable distance as, as I understand it, conduit can be tacked to a permanent structure and doesn't need to be buried which I am guessing they did here to avoid the burying requirement.

Strange, you can clip an armoured cable without burying it.

Pictures might help but no issues with clipping it to a permanent concrete structure in my eyes which is essentially what you have. The cable being in conduit is a bit odd really.

I’ll try and get some pictures but may be a week or two.

From what has been said it sounds like armoured cable (in or out of conduit) can be clipped to the side of the concrete footpath at ground level.

I guess, at ground level its to protect it from general gardening tools and machinery. Makes sense to me.

I've just done 2 runs. One burried (across my lawn) and one cleated (along the side of the house wall)

I doubt it’s armoured cable inside the conduit. It more likely to be glands which are designed to screw into conduit and then the SWA jointed to a different type of cable more suitable for conduit.

If it is SWA, it would have to be a pretty small conductor size. Also if the conduit is rotten I can’t imagine the cable inside is going to be in very good condition either.

Interesting. I’ll inspect it more closely when I’m next there thanks.
