conduit work

[ipf]

Look on youtube there is a demo on how to measure & bend conduit by poly friendshu

POLY FRIENDSHU ? Is that some kind of mind bending ?

Its using a American hand /foot bender I think on U Tube, not our UK bender unless I am wrong and they sell them in this country.

An old boy showed me how to make a sledge out of 20mm Galv.outstanding bit of work.could have done wi a couple of boxes to get the wires in tho.

One of the best ways to learn how to bend conduit and work with metal containment systems is to be on projects where this is the main means of distribution of the electrical installation. Working with those where bending conduit and fabricating trunking and traywork is second nature.

You need these skilled tradesmen to not only learn how to work with metal containment, but it's limitations of what you can and cant do as far as final wiring of these systems. It's no good having a neat pristine conduit run, that is impossible to wire!! ...And i've seen that a few times. ...lol!!

Most of the practical installation work, during my training was metal containment systems, that and heavy cable installations. I can still put my hand to it now, and often offer to help a tradesman on site having problems with a particular set he needs to get in. I think once learnt, it's something you don't forget, even if you do cock-up the first attempt!! ..lol!!

Can always tell a sparks ingenuity by the hiding places he can find for those cock-ups.

You can always hide a coupler behind a beam or something lol

As far as I know, the Americans use different gauge conduit to us, it must be much smaller to be able to use a hand bender...unless all American sparks are bodybuilders too. Try doing 25mm with your hands!.

I have a bender but due to the cost to the customer, I mainly use pvc or armoured.

American pipe is called EMT and is a lot easier to work with than our galv.

I remember a foreman commenting how the amount of conduit withdrawn from stores went up as Christmas approached.

theres a nack to it, and there is people who do it everyday and then theres people who dont. im pulling alarm cables , door access etc at mo and when the work is done and the other boys go smoke there ****e i go bend conduit with sparks from different firm , made myself a cable reel on thursday, used 25mm pipe and il tell ya i ws pulling bender and my foot off the ground just to do 90's .. then few 80s then 60s and was a raver blurp,

No wonder no one knows how to bend tube any more, Now when you take your AM2, all the containment is fitted for you, all you do is wire.
I was an apprentice to an 'old boy' he never wanted any slip marks on the tube.
The good old days, were it was it needs to be neat, not 'it will do'.

And it's not a screwed conduit system either, coupling is by means of set screws similar to our now obsolete 1/2'' slip conduit, except it has welded seams... The stuff wobbles around like a good in!! lol!!!

Yes I had a look on U tube on their bending methods they use a hand/foot bender, saw them bend a 90 degrees bend a offset/crankset/bridge.

They use electrical or hydraulic bending machines for there galvanised Rigid screwed conduit system, that stuff has a pretty thick wall to it. You may, be able to bend there 1/2'' rigid with a manual bender (equivalent to our old 3/4''/20mm ish) but you'll have problems with the 3/4'' and above sizes... lol!!!

Not a lover of Yank conduit systems, as they tend to use, what i would call hexagon shaped knockout back boxes. To say the installations look cheap and nasty is an under statement They do have proper cast conduit boxes but they rarely seem to use them!!

Anyone remember aluminium conduit?

It was about in the late 70s early 80s. You had preformed threads, pushed the tube on to the reverse side of the thread and had a "ringing" tool to join the 2 parts together.

Absolutely rubbish! Used it in a school, went back 6 months later and found the kids had had great pleasure in kicking the conduit and flattening it!
