FAQs:
How to size cable tray NEC?
To determine the required width of a ladder or ventilated trough cable tray as per Section 318-11(b)(4). Space between cables must be equal to 2.15 times one cable diameter — 3 x 2.15 x 1.07 inches = 6.90 inches. Total cable tray width required is 8.56 inches + 6.90 inches = 15.46 inches.
How do you calculate cable tray capacity?
To calculate the cable tray capacity, multiply the width and height of the cable tray to find the total area, then multiply by the fill ratio. Divide this by the cross-sectional area of a single cable to find the capacity.
How is cable size measured?
Measure the Diameter
Once you have cut your cable, you can get the diameter by measuring the cross-section of your cut in inches. Measure from one side to the other side in a straight line. Be sure to measure only the wire — don’t include the insulation in your measurements.
