Best Way To Mark And Set Conduit Out

[Gingerbolt]

when marking out conduit and fixing it which is the best way would first make the piece of conduit, or mark out your saddles?

 

[Lurch]

Depends which was most important to get right, and whether it is galv or PVC, and where it is and what it's doing, and what it contains.

Start with the long piece's first then you can use the off cuts for the short bits less waste that way

Are talking steel or PVC ?

Don't use inspection elbows , bends & tees for a start  !  In either medium .   Three right angles is pushing your luck ....what can I say  if you've never done it ?     Don't do what seems to be a popular pass time at the moment ....trying to wire it with twin/E .

It's great you want to give it a go if you have not done it before - but for sake of giving an answer, Saddle up first, Any obsticles, bends, accessories ect I always try and get a saddle 300mm either side of the above (As long as that fits obv, if its super tiny small area then adjust sizes accoringly.

So 300mm from each bend ect then measure the free run space and put your other saddles at equal distance apart no larger than 1m for each fixing.

Once you have done your chalk lines got your saddles up then you start installing the conduit. Get threading and bending to suit your job and your good to go. As with any job Fail to plan is planning to fail.

I have never tried either, but i have to do a bit soon!! Personally, i will set out the saddles first, and then bend the conduit to suit. Provided you read the instructions that came with the bender it is a piece of piss to get the bends in the right place..

For my record bender... You want a straight bit of pipe 3 feet long from one end to the back of a 90 degree bend. Mark 3 feet from the end of the pipe. Stick it in the bender. Using an engineers square on the pipe, align the blade with the outside edge of the die. Pull the bend, Exactly right every time!!!!!!

I have done pipefitting, so cannot see the problem with conduit!!

john..

It just appears to be something else that is not taught nowadays...other that one bend in a 6' square practice bay at college if you are lucky

That sounds very complicated Apprentice ...........  set your tube , pull your bend ...hold it in place , level etc , then mark your saddles .  Then if its not critical , stick an isolator or whetever on the end . 

If you're pulling a right angle and then a double set  , either get someone to hold a level on it in the bender,     or  chop it off , thread it , make double set in straight bit  and screw it back on .

Shortest 90 deg. bend you can pull is 7"  if I remember correctly ..and the old favourite is  21"  for the bit between boxes for a fluorescent fitting .

Actually I don't think you can learn it on here TBH .     I worked with a sparky over the years , (Pricey where are you ?)  He could look at , say a column on a brick wall,    10 feet away,  pull a double set , straighten it , hand it to you saying  " That'll fit "   And it did.

This is the way you actually do a conduit install ? I must have been doing it all wrong over the last 30 years lol. Mark up first and do the job properly ffs.

One thing I cant stand about the electrical trade, and it seems to be more prevalent than in other trades, is folks saying that coz summat has been done in a different way to the way they would do it, it must be wrong. Sterling attitude there Diddy Fa, keep it up mate

Deke was around when conduit & electricity was invented. i bet he knows a lot more about it than you ever will

there is always more than 1 way to do something, just because you do it differently does not mean the other ways are wrong

 

[DiddyFA]

Lol at the 3 descoobs or whatever they are. Oooh he criticized my mate ffs. Grow up. You think im 18yo or something ? Deke may well have been around since the man who made fish spread was popular...doesn't make the way he suggested doing a conduit job correct. Maybe handy andy would do it that way but it doesn't make it right does it ? Anyway descoob away till your hearts burst with pride lol. I have better things to do - my original post on the thread instructing on how to do so still stands as the correct way to do it...it's not even a "slow" way or anything it is just simply the way a tradesman would do a decent conduit job.

Now I bid this thread farewell and wish you all a good Christmas.

What complete bollocks. There are several correct ways of setting conduit out, obviously what with you being a foreigner there is some language/skills translation issue so probably best if you just find yourself somewhere else to spout nonsensical drivel.

most of the time when i do anything with conduit, all the saddles are fitted in place first... but the main difference is i know how to do it more than 1 way, and accept that other people have their own methods of getting the same end result

I don't really want to cross swords with Mr Diddy on how to install conduit , I'll just say he has his set method & he's sticking to it .

I , on the other hand , take the easy & simple  route to most tasks , such as :

I see guys drill a 20 mm hole in a board , say , then spend a load of time getting a set just right so that it matches the hole and a bush can be fitted,  where as I would pull the set first...offer it up to the board , mark the hole , drill it for a perfect fit.   

You do it your way Mr Diddy , I'll do it mine . The end result is the same ....conduit is what it says ........a conduit to carry cables from A to B . Nothing to get exited about .  My job will look just as good as yours ....certainly you can do chalk lines , fix saddles, drop tube into saddles , whats the big deal? , just another method.

I think after tubing a few new hospitals , schools , factories , BT Tower  , car factories , production lines etc etc  I might have gained a little knowledge  on how to install conduit . 

Edit:  And was merely trying to advise the original poster .
