Does the cable tray have a separate grounding How is it connected

Every metallic cable tray must be grounded in accordance with Article 250 regardless of whether it doubles as an equipment grounding conductor. 18 (A) does not require the tray system to be mechanically continuous, but it must be electrically continuous and bonded. If an EGC cable is installed in or on a cable tray, it should be bonded to each or alternate cable tray sections via grounding clamps (this is not required by the NEC® but it is a desirable practice). The EGC is the most important conductor in an electrical system as its function is electrical safety. It is also covered in NEMA Standard VE-2.
