Advice on Pulling 6 mm2 single core cable through 20 mm Conduit

Maximus Rumpas · Dec 14, 2012

Hi,

I would like to ask your advice about how difficult it might be to pull cables through 20 mm plastic conduit. (easy, moderate, hard, impossible)

I am running two separate lines for a cooker and hob in 6 mm2 single core stranded cable. Both runs will follow the same route.

4 meter run from distribution board via 90 degree inspection bent to an inspection box next to soil stack.

Next 2.5 meter run through Bathroom/Kitchen wall to an inspection box under sink (minor set to allow for wall levels)
Then either
4 meter run, chased into wall via 90 degree inspection bend to a third inspection box.
or
4 meter run via 300 mm drop to Floor level - two 90 degree inspection bend to the third inspection box.

Lastly 1.5 meter run to cooker or hob isolation switch.

On completion permanent access to inspection boxes - limited access to 90 degree inspection bends.

Your thoughts please.

Kind regards
Max

personally i would have run one 20mm and 5 x 6mm should go through with swept bends you can share the earth and t box to first isolator then angle box up to second isolator i dont see a problem i am positive you can get all 5 x 6 mm in one 20mm conduit unless you are useing double insulated but there is no reason to if its in conduit

I take it then, that you have never heard of maximum conduit fill?? Your suggestion would contravene just about every rule in the book!! lol!!

That doesn't even look like trunking to me, more like structual steelwork??

Needless to say, that amount of fill through a male bush, is just not acceptable!! CODE 1++!! lol!!

ahhh, go on. sure i could get a couple more in there with a bit of lard.

as you seem to be quite the expert can you tell me the maximum % fill in a conduit and then also tell me what the % fill will be with 5 x 6mm singles in it ? my guess is that it does not break any rules but not having tried it i dont know if it breaks the rules or not so i better just ask the expert !!

Why don't you work it out for yourself and prove yourself wrong.
