How much volume do cables occupy in cable trays
NEC 392 limits cable tray fill based on cable type and size. Fill is calculated as total cable area divided by usable tray area. Select Fill. How do you size a cable tray capacity? Sizing capacity involves determining the total width or area required for your cables plus a reserve for future expansion (typically 20-50%). 0133 sq in each, the screen is about 0. The following formula is used to calculate the cable tray capacity: Variables: To calculate the cable tray capacity, multiply the width and height of the cable. Many beginners assume that a 100mm x 50mm tray has an area of 5000mm², so they can fit 5000mm² of cable into it.
