PVC Conduit Question

No he was a professional plumber.

That figures, doesn't it?

 

[freddo]

Somewhat inventive to say the least, DIY job was it?

I'm not sure, but all the wiring on the, rather large, site was installed to a similar standard. Thank goodness the place is now permanently closed and I believe the buyer of the site intends to knock most of the buildings down.

 

[littlespark]

Please please please can we see a pic of that...

If you must......

Yes, I just left the ends open. Bad of me.
Built it up with the cable inside already, and it’s glued. The bends have a corner inside them, rather than a sweeping smooth run.
Only for ELV and cctv signal.

 

[Simon47]

Going off at a tangent ...
Interestingly I've noticed that for galv conduit, you can get solid (non-inspection) bends, elbows, and tees. I'm thinking that threading stuff through conduit with non-inspection tees could be "interesting"

 

[westward10]

Solid bends and elbows have always been about a tee seems odd but have just seem them online. How would you wire a tee and guarantee it went the correct way.

 

[Simon47]

I guess you'd need a bit of a set on the end of your tape - and keep the tape the right way round. I'd be more concerned about getting past the inevitable edges to get into the next tube.

Hope you allowed a degree or two for gravity flow...

use string and a henry. suck from the place you want it to come out, with any othe outlets plugged or taped over,.

Never used a bending spring. I will order one and do all my straight cuts and see if I have any scrap left to practice with.

Just a tip , when you get your spring attach a bit of singles looped quite long on the end, so when you have made a set you can pull the spring out.

Cheap LED sticky tape stuck to the underside of my pipe from #54.... bathe the front of the house in blue for Thursdays clapping for nhs

Can you make it flash?

 

[DPG]

Can you make it flash?

Or switch it to red and get the wife earning some extra money

 

[littlespark]

Can you make it flash?

It’s 3 colour, RBG.... can fade or jump between the colours, or change in time to music.... but the mic and controller are inside. I’d need a speaker inside and out to get the effect

I’ve got a wife for that, tel

They want a rainbow in the window.....

BS
If anything, I’m increasing their values...
You should see it at xmas time...

Now try telling my kids they MUST draw a rainbow for the windows.... not a chance.

 

[westward10]

Trampolines, hot tubs and accent lighting is a sure way to devalue the neighbourhood.

No trampoline or hot tub. My back garden is on a slope, so water would spill out, or the kids would bounce out onto the main road.

yes. I wasn’t keen on running those lights out.... but it’s for the kids.
They won’t last long... not entirely IP rated for a start.

and a bit of fairy liquid on the spring.

Down south, we use olive oil...

Thanks I’ve ordered some 20mm conduit. It’s to run some 10mm twin and earth from the CCU to the garage CCU as the guy who converted the garage into a room just left the old 1.5mm SWA cable in. But my uncle who is a spark of 50 years said that’s no good. So the SWA is coming out and the T&E going in it’s place. We’ve done the cable calcs so 10mm is fine. The reason we couldn’t fit SWA is the room where the CCU is has been fully refurbished and decorated. We managed to fit the T&E before the was put in.

Now would I need to buy some draw tape or is there another method for the bends? As the T&E goes down the conduit fine as it’s less than a metre between the house and garage.

Thanks

 

[Pete999]

What siz conduit have you bought?

 

[Mike Johnson]

Stick your vacuum cleaner on the end and blow/suck a draw string through, and use that to pull the T&E or use the SWA to pull a string through when you take it out.

 

[westward10]

I would be using 25mm for 10.0 T&E.

 

[DPG]

I might have missed this, but presumably there was a reason why SWA was originally going to be used? Is the route definitely suitable for T&E?

 

[RDB85]

What siz conduit have you bought?

20mm White PVC conduit.
[automerge]1587562078[/automerge]

I would be using 25mm for 10.0 T&E.

I’ve bought the bits now. It’s just the bends that are a bit tricky. But I think that goes for anything other than singles and CAT5E. Plus it’s little hard to take them back given the current situation.

 

[westward10]

You will find it nigh on impossible to pull a 10.0 T&E through that.

 

[Pete999]

20mm White PVC conduit.

Could run into difficulties trying to run 10mm2 through 20mm conduit

 

[RDB85]

You will find it nigh impossible to pull a 10.0 T&E through that.

As I say it’s hard to take it back given the circumstances. My uncle did say 20mm would be fine when I asked him.

 

[Pete999]

Will it be a straight conduit run? how long is the run? sorry my bad you have already said. Still think you may have problems, getting the cable down that conduit.

 

[davesparks]

You won't get 10mm T&E through 20mm conduit, especially not with any bends in it.

If installing T&E through conduit you kind of need to feed it through each piece of conduit as you go and almost build the conduit around the cable.

 

[RDB85]

I see well I’ve contacted the company I’ve bought it from to see what they say. Due the current circumstances it’s difficult to even swap it for 25mm conduit and fixings. Plus I don’t fancy buying it all. Then trying to take the 20mm conduit and fixings back and they can’t do anything
[automerge]1587563656[/automerge]
I will see what they come back with. I may use it for something else. I’ve some outside lights that have two wiska boxes for each light so may take them down and use the conduit, inspection bends and through boxes so you can’t see the flex cable.

 

[Mike Johnson]

Single core cables may be your answer, not T&E.

 

[DPG]

Any answer for post #78?

 

[RDB85]

Single core cables may be your answer, not T&E.

The T&E is already in, just needs the conduit. So I will order some 25mm conduit and inspection bends. As I am not experienced enough to try a bending spring. It’s going behind a gate anyway so your never going to see it from the front of the house.

Originally when we moved in was a 32amp MCB feeding some 1.5mm SWA to the garage. At the time it had one double socket and a 8ft florescent tube. The garage is now a room with some led spots gw10 I believe and 4 double sockets currently with a TV, Virgin Media Box and a Electric Heater, and Wine Fridge.

So my uncle deemed the 1.5mm SWA to be no good for what was now in the garage. So as he had some 10mm T&E on his van we fitted that as he said it is more than enough and easier to fit than SWA which would mean making a right mess of the newly decorated utility room.

 

[DPG]

Ah right, so there is no requirement for armoured cable now then. Fair enough.

32A MCB with 1.5mm cable - they were optimistic with that eh.

On a separate note would you use a through box or a Wiska Box to house some flex and choc block. As the two wiska boxes that are currently up, ones black and the other is grey and two different brands.

Would the conduit fit inside the wiska box?

RDB will probably get away with 25mm conduit, but forget the 25mm inspection bend 10mm2 will never fit, a solid bend maybe, but not an inspection elbow, the cable is just far too big and far too rigid in manufacture.

I tend to use a through box with an adaptor and gland.
Assuming it's basically a flex outlet for lights or some such.

If outside don't forget gasket.

Would you recommend a bending spring Pete or another method?

WHAT SORT OF ANGLE ARE YOU CONTEMPLATING USING?
Remember you are using a fairly hefty cable, so getting it around a bend will be difficult whatever method yo use, could you not run it in the conduit down the wall and take it into whatever without ciconduit, after all 10mm2 has its own mechanical protection.

I understand what your saying. Only other method I was thinking would be Trunking but I would look odd.

 

[westward10]

Davesparks suggestion is best try and build the system around the cable.

I understand what you mean. It’s just the bends I am struggled with. Would flexible conduit be any easier?

Or maybe a two way angle box?

 

[Pete999]

Better Odd than a badly installed cable. prone to heat damage due to the badly designed install method tight bends and tight enclosures are not a good idea,
Question, is there actually a need for conduit in this situation, many people just bury the cable as is as long asit's protected by a RCD.

It's coming down the external brick wall Pete.

Buried or surface?

 

[JohnsonsAces]

I would avoid manufactured bends and elbows they look terrible in any instance. Get a bending spring and use sets wherever possible and use BESA boxes as opposed to the fittings you suggest.

Hey mate,

Quick question, what do you mean by use sets?
