Cable Trays

Yes, where it's listed for the duty. NEC 392.60 and IEC 61537 both permit a metallic tray to act as an equipment grounding conductor, provided its cross-section meets the fault-current table and every joint keeps electrical continuity (galvanizing removed at bonding points, jumpers fitted across expansion joints). Confirm the tray is approved for EGC use before you rely on it for that path.

Plan for bends (horizontal and vertical), tees, crosses, reducers, covers, couplers or splice plates, and support brackets, all in the same material and finish as the tray. One mistake we see constantly: ordering tray without accessories, then air-freighting a second small shipment of bends and tees at a premium once the gap shows up on site. Count the full accessory list into your enquiry from the start.

Support spacing usually runs 1.5 to 3.0 m depending on load class and cable weight. A tray rated at a 1.5 m span will deflect noticeably more at 3 m, so span and load can't be judged separately; they're two sides of the same number. Tell us the cable weight per metre and your preferred support spacing and we'll confirm the correct gauge and load class.

Closed trunking shields cables from dust, falling debris, mechanical impact and casual contact, choose it for switch rooms, exposed building runs, walkway-adjacent routing and areas with public access. Open trays cost less and dissipate heat better, but they expose the cabling. Many EPCs mix the two: trunking in occupied zones, trays in plant rooms.
