cable in conduit

[sam80]

How many 4mm can you put down a 20mm conduit???

It depends on many factors - length of run, number bends and sets, cable and conduit tolerances, cable grouping, current carrying capacity and free air space etc. However, you should be able to work out the number of cables you can safely draw in for yourself mate with help of the OSG+A1:2011 Appendix E, but be aware the electrical effects of cable grouping and current carrying capacity are not taken in to account in the simplified filling calculation.

Look in the OSG or BGB

Why not try, then once you know, you won't try that many again, or put in 25 mm conduit hahahah
