steel conduit help

[h901]

hi everyone

i've recently started using steel conduit and so far most of the jobs where i've used it have been fairly simple (straight runs). i've got a job that requires quite a few 90 bends to be made (i've bought a hilmor bender and have been practising using it) i've just got a few questions which i'm hoping the members with more experience than me can help with. any other tips and tricks will be very helpful too

1) should the saddles be installed first?

2) how would one connect conduit with a 90 bend to a straight piece, if for example the run is quite long - something like - I________I
is this done before or after fitting it to the wall, as i tried doing it once when it was already fitted to the wall and couldn't get the couplers to hold (before fitting to the saddles), as i was screwing one side on, the other side of the coupler was screwing off the other conduit

3) what are conduit nipples used for exactly?

4) when trying to make a 90 bend at around 1.5m in the conduit, i wasn't able to do it with the hilmor shorty as the conduit hit the floor before the bend reached the correct angle, so instead i cut off the top of the conduit and then re-attached it later with couplers (was this correct)

apologies for the long questions and thanks in advance

For joining conduit to a piece already in situ, use a running coupler

Hello mate

1) yes!
2) spin them together 1st or use a running coupler to join in situ
3) female to female connections
4) bend up!

Hope that helps

1 saddles should really be screwed to the wall 1st

2 running coupler where it can't be fabricated on the floor then installed or manufacturers bend.

3 1 example is two conduit boxes next to each other. 1 right angle box and a stopend with no conduit in between (two cameras mounted on these boxes side by side for example).

4 turn the stop bar to the bottom and bend upwards.

Missed the one about choice words and going to the bunker, never realised I was that popular

I prefer to see a galv through box used instead of a running thread as I don't like seeing any thread on show. This also provides a pulling point to help with wiring

Neither do I Perci, but there come a time when you have to use a running coupler, why have you stipulated a Galv box?
