How to make bends in shave-type cable trays
You can buy a manufactured 90 degree bend or make one on a cable tray bending machine but in this video I show you how to make one using a metal bar. more. Depends on the type of cable tray, you can buy 90° tray fittings or use a speed square with a straight edge and a grinder or skill saw to cut 45° cuts. Construction of a flat 90° bend (A) The amount of tray lip to be removed is equal to 2, 3/4 the width of the tray, half of this measurement will be removed on either side of the centre line. This involves a few essential steps to ensure a successful bending process. The first step in preparing the. Table 2 of NEC provides the minimum radius of conduit bends. Is there some similar table or other reference available for the minimum radius of cable tray bends? For example, if we have to make a field bend for a 12” (300mm) metallic ladder tray using straight sections of this tray, then how much.
