6000 Raceway Wire Fill Capacity for Power
NOTE: Capacity range is calculated at 20% to 40% of raceway area as stated in a proposed revision to the Commercial Building Standard for
Telecommunication Pathways & Spaces, TIA/EIA-569. Actual wire fill capacity may vary based on applications, cable types, and
number, as well as type of fittings. (Fitting may cause additional variances to the fill capacity.)
