|6. Conduit, Cable Basket and Ladder Fill Recommendations<br />
SECTION 6: CONDUIT, CABLE BASKET AND LADDER<br />
FILL RECOMMENDATIONS<br />
Conduit Fill Recommendations<br />
Conduit fill states the maximum amount of space that the installed cables should<br />
occupy in a given size conduit expressed as a percentage of the interior volume.<br />
When designing a conduit run, consider not only the cable being installed now but<br />
also the likelihood of having to add cables in the future.<br />
Table 6.1 (right) makes recommendations for the maximum cables to be installed<br />
in conduit.<br />
• Clearance should be ¼ inch at minimum and up to 1 inch for large cable<br />
installations or installations involving numerous bends.<br />
• When calculating clearance, make sure all cable diameters are equal.<br />
• Do not exceed recommended conduit fill requirements.<br />
• Typical OD for twisted-pair cabling is 0.25 to 0.35 inch.<br />
