Conduit runs over 10 meters

[2396help]

Hi, as my name says im just trying to do the project on my 2396, im looking into my options of cable management and on route i have stumbled across conduit rating factors p142 yellow osg (ive never worked with conduit) and the rating factors only go up to 10m, is this 10m maximum length or 10m maximum length between inspection boxes

Many thanks

Welcome to the forum, may I tempt you into applying for our trainee section where you are amongst like minded trainee's and we have mentors to help with the kind of questions asked by those learnng the ropes, it's not a requirement but I would recommend it

Hi bud,is it plastic or steel conduit? because other factors will be at play,not least,earthing and thermal expansion :stooge_curly:

 

[2396help]

Im going to design it in metal conduit

Thanks

Inspection boxes are placed so as to make the pulling through of cables easier.

In days of old we fitted a pull in box every two lengths of conduit, or every two 90º bends or two double sets.

Every 2 lengths is a bit oot IMO, my nylon draw tape is miles long.:smile5:

It all depends, on size of conduit, size of cables, number of cables and number and angle of bends.

an idiot on a previous job wanted me to pull 6 x 4mm cables through 5 lengths with 2 90o and copex on the endend with no bends between

I am also interested in doing the 2396, but my local college doesn't seem to do it.

I was only asking because of the OP's location. I've done some courses at Brian Scaddan Associates in Waterlooville and wondered if the OP had chosen the same.

Were they any good? It'd probably take me about an hour and a half to get there, which is just about do-able.

I would expect a course offered by Brian to be very good.
