Traycontrol 500, 500-C, 530, 550 TPE, 600, 600-C and X cable products now are tested in accordance with UL, CSA and NEC for applications in which bending in cold temperatures as low as -40 °C (-40 °F) is required. These products have a UL-listed tray cable with exposed-run (TC-ER) 90 °C dry/wet approval. Products with the 90 °C dry/wet ratings allow engineers and integrators to design electrical systems for maximum ampacity without concern for the environment (dry/damp/wet) in which the cable will be located.
