conduit run,how long?

[Tony Moscioni]

The OESC or CEC contains only the requirement that the raceway has not more than the equivalent of four 90? bends, including the bends located at an outlet or fitting.

Raceway runs shall be so constructed that the conductors may be easily installed or withdrawn without undue injury to their insulation.

There really is not a length restriction, only the amount of bends within the conduit system itself to not be exceeded.


Rule 12-942 Maximum Number of Bends in Raceways

Where it is intended that conductors are to be drawn into a raceway, a run of raceway between outlets or draw-in points shall not have more than the equivalent of four 90? bends including the bends located at an outlet or fitting.

hello every one

we have been having a conversation on how long can a straight conduit run be ?
most agree that 100 feet is the norm,but cannot find any restrictions in the code as to length,some have said that underground runs could be as long as you want, but that is still not found in the code either.,at least not the ontario code i have .
If any one could help ,thankyou
