We know that we need to fit 157.38mm², in the conduit but cannot exceed the 40% fill rule. Using the table, we find that EMT conduit with a nominal trade size of 27 has a 40% area of 215.65mm² (trade size 21 is 132.03 < 157.38) Therefore, as per the CEC, we would require at minimum a 27mm EMT conduit to house the 3 #4AWG RW90 conductors.

The Canadian Electrical Code (CEC) and the National Electrical Code (NEC) in the U.S. stipulate that conduits should never be filled more than a certain percentage (Table 8 in the CEC). The important figure to remember is that when there are 3 or more non lead-sheathed conductors the maximum conduit fill is 40% (31% for two conductors, and 53% for one).
