Conduit Fill Table
This conduit fill table can help you make wiring decisions. Use it to determine how many wires your conduit tubing can safely contain. The horizontal numbers at the top of the graph refer to the size and type of conduit. The wire gauge can be found via the vertical column. The central numbers represent the number of wires that can fit for each conduit and correlating gauge.
