conduit

mackmick

Help needed please .I am moving an out side shed which is fed by cable through metal conduit I am omly moving the shed a few feet .I want to replace some of the metal conduit but not the original wiring .Can I connect the plastic conduit to the original metal and if so does the plastic conduit have to be glued at the joints Any Help would be appreciated Thank You Mackmick

Do I understand you are giong to use plastic conduit outside.

We have just been told that to run electricityto our garage from the house we have to have armour plated wiring for safety reasons.

Am I wrong.

Armoured cable is the safest way, but it's pretty expensive stuff. Conduit is - or, always was - a way to allow you to run ordinary cable outside. The regs may have changed, but it always used to be the case that you had to use either armoured cable or conduit.

I think it also matters if you're going to bury the cable, as opposed to running it along a fence, wall, etc. Buried cables need much more protection, as they've got to withstand being sliced by spades etc. I *think* that buried cables really need to be armoured, as conduit on its own won't supply sufficient protection in that situation.

i tend to use old scaffold poles, buried. perfect for running cables inside.

What happens when the bodies decompose?

Can't you just get the metal conduit extended?

Takes me back 25 years to running and bending conduit at a Shell aviation Fuel Depot at Heathrow lol

Yes, ours is going to be buried, about 16 feet from the house to the garage, I dont mess with electric, let the profs do it.

Very wise ! Saving money is great up to a point, but there comes a time when paying a pro can be money well spent. Electrics + outdoors = potentially nasty situation if you're not totally sure of what you're doing :-)

The armoured cable (or metal conduit) that exists probably has 2 wires (live & neutral) running through it & the external metal of the sleeve (armour) acts as earth.

To join plastic on means you will have no earth at the end. That is both dangerous & illegal.

I do not know the regs on joining armoured cable outside but it is possible & will not be too expensive to add a couple of metres onto the existing run. Joining a couple of metres in metal conduit will not be expensive either. Keeping continuity of earth to you shed.

Both these ways are more expensive than plastic but cheaper than a funeral.

You can always bond an earth cable to the conduit and don't be a drama Queen scaring posters with the costs of funerals.

Kopex is another option, flexible conduit for the uninitiated.
