Cable Trays
Importers in Nottingham

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.

Four questions determine the configuration. Is the area classified (Ex zone)? If yes, the tray must be electrically continuous per IEC 60079-14 bonding requirements. Is the routing under covered walkways or fully exposed? Exposed outdoor routes in the Gulf need 85 µm HDG and screw-fixed covers for the khamsin wind season. What's the cable mass per metre? Heavy armoured cables above 30 kg/m need ladder Class 10 minimum. Is the installation on EPC or owner-direct supply? If EPC, the BOQ standard is usually IEC 61537 or NEMA VE 1, we confirm which before quoting. We have supplied to Saudi Aramco, ADNOC and Qatar Petroleum projects and hold their vendor qualification documentation.
