steel conduit help

[7029 dave]

I have known it always being a mate's or apprentices job on most sites. And why not ? It's the sort of skill that takes time to master so lots of practice makes sense.

Understand that, but he was referring that qualified Electricians do not carry out that type of work, as if it's beneath them. IMO it takes skill practice to be a master in this work, anyhow they have to be shown, you just can't pick up stocks and dies, bending machine and away you go. I am only talking through my experience.

Yes, agree with that. As a mate I did a lot of the conduit work, but so did the supervising electricians.
A typical sort of job would be me and a sparky measuring and forming a particular piece together, marking a floor template, noting all the measurements, then once shown I'd get left to make a couple dozen more of the same.

For the less repetative jobs i'd usually work with an electrician to construct a system.

I was lucky though. I mostly worked under guys with a great work ethic. I worked with guys that had decades of experience in industrial work, offshore work, working as team supervisors, yet sweeping up was beneath none of them.

You can't buy the running coupler, you make them yourself as and when you need to.
The running coupler is, if I can explain it in words, as follows. imagine you have to join two pieces of conduit by the running coupler method, and you have a MALE end.
On the piece you wish to join there is also a MALE end, extend this thread by tonjust over the length of a coupler and a locking ring or lock nut.
Run the lock nut on to the long thread until you run out of thread, now run the coupler on, you will be left with a MALE end on the conduit that is fixed to the wall, now install the conduit with the coupler and lock nut until the MALE end and the conduit with the coupler and lock nut meet, now turn the coupler onto the MALE end and then lock it in place with the lockring.

I hope that is understandable

I've tried to understand what you meant but for some reason still don't fully understand. I appreciate your help though.

Could somebody possibly show me a picture of how a fitted running coupler looks (whenever you get a chance) thanks again

 

[westward10]

The end of one conduit thread to the full length of a coupler and space for a lock nut, fit the lock nut first and then the coupler all the way down so the thread is flush at the end. The conduit you wish to join thread to half the length of a coupler. Butt the two pieces together and you should be able to run the coupler back over the end without the coupler, tighten the lock nut to the coupler.

[7029 dave]

No sound, he is preparing the runner to join onto the piece of conduit. (not shown). lock ring/ nut is important. Sorry tried to get picture can't find one.

 

[h901]

Cheers lads, it all makes sense now.

 

[westward10]

Yeah the lock nut is important because the coupler will tighten to the end you thread it to and not necessarily the end you are unwinding it from, the lock nut will bite it up.

Hi - this looks like it, I think ...

What do you mean you think

 

[Midwest]

Can some tell what a 20mm nipple looks like

 

[Risteard]

Don't forget it is critical to paint the exposed threads after making the running coupler.

Oh ok, is there any specific paint to use to keep the look consistent?

 

[Leesparkykent]

Galv spray

I see someone has found a diagram, well done Lee

A "chapel hat-peg",is the answer to that question

 

[Pete999]

A 20mm nipple is a coupler sized threaded piece of conduit, an example of the uses of a nipple would be to screw into an unused conduit box out let that you wished to add some extra conduit. 20mm Conduit Nipple - https://www.tlc-direct.co.uk/Products/CO20NIP.html

You legend, didn't even know such a thing existed. Cheers

 

[Midwest]

Cleaned and degreased first of course

 

[Sparkie30]

Since you boys like conduit alot, you mights aswell visit Bletchley park. 25mm also black enamel. Dont miss it.

 

[Wilko]

Secret coding machines and Conduit - still my beating heart !!!

 

[westward10]

Ever since Pete posted that American vid a while back I seem to be only say and think "canduit"

Or to use a runner on, through box etc.

Did you do it.?

 

[GMES]

Oh yeah Running couplers I do miss those beauties

 

[Flanders]

A good electrician should never have to do a running coupler anyway

 

[7029 dave]

No don't agree, sometimes you can not turn on to piece, with big long sets, it's just impossible. I KNOW have done loads of it.

Good electricians know this Dave

So you have not done much conduit then Flanders.?

Nah "Raceway" that's yank for Canduit I think

Yes I Have done loads !!! I use to do hospital installs and a good electrician gets his apprentice do all the runners for him

 

[Risteard]

LOL.

 

[Flanders]

Sorry couldn't resist only dave westward and pete fell fot it , just thought i would give 24 hours , thought a few more would have thown some abuse my way

Fair play. I myself would do what needs to be done.

@7029 dave
I did alot of conduit there, main building also that tray and trunking long runs in the middle. In main building all lights are controlled by rako.

Rako is that the same as Dali?

 

[Sparkie30]

@Pete999
No rako controls your lights via phone app or/and all switches wired in cat5
Dali is just dimmable light which requires a dimimg pair white and pink cables normally.

Hope i explained that right.

DALI is Digital Addressable Lighting Interface. Very common in commercial jobs now.

Well that told me, didn't it

 

[davesparks]

Rako is a company who manufacture lighting controls.

DALI is a control data protocol which uses a single pair of conductors to carry data to all light fittings and controls.
