What is space factor for conduit?
F or 38mm conduit use the 32mm factor x 1.4. For 50mm conduit use the 32mm factor x 2.6. For 63mm conduit use the 32mm factor x 4.2.
What percentage of conduit fill is required?
Finding minimum available conduit area The National Electrical Code establishes that if a conduit only contains 1 wire, the max fill percentage is 53%. If it contains 2 wires, the max fill percentage is 31%. And if it contains 3 or more wires, the max fill percentage is 40%.
What percentage of conduit can be filled with wire?
53%
One wire: maximum fill is 53% of the space inside a conduit. Two wires: maximum fill is 31% Three wires or more: maximum fill is 40% of the conduit’s total available space.
How many data cables are in conduit?
6 Data cables
Do not install data cabling in the same conduit as electrical wiring. A conduit size with a diameter of . 075 inches can accommodate up to 6 Cat6 plenum rated cables. This may from one manufacturer to another but as a thumb rule, the average is 6 Data cables with a 40% fill ratio capacity for the EMT Conduit.
How many Cat6 cables are in conduit?
Do not install data cabling in the same conduit as electrical wiring. A conduit size with a diameter of . 075 inches can accommodate up to 6 Cat6 plenum rated cables. This may from one manufacturer to another but as a thumb rule, the average is 6 Data cables with a 40% fill ratio capacity for the EMT Conduit.

How to determine trunking size of PVC cable?
Single core PVC insulated cables in straight runs of conduit exceeding 3m in length OR in runs of any length incorporating bends or sets. To determine the trunking size needed, multiply the quantities of each cable by the appropriate factor, and compare the total with the trunking capacity figures shown.
