Interference can occur if both high-voltage and low-voltage wires are routed through the same cable tray
Both low voltage and high voltage wiring need to maintain some distance from each other or be separated by a barrier within the conduit. This helps prevent the risks of electrical fires, shocks, and other potential issues. To ensure the safety and proper functioning of electrical systems, specific. ETC's preference is to keep data and power in separate conduits/trays because signal interference can occur when low voltage control wiring is run with branch power wiring. Use of Class 1 wiring methods will not protect against signal. Low voltage circuits are generally defined as those operating at 50 volts (V) or less, with common examples being 12V or 24V DC used for thermostats, security systems, and data transmission. There may be exceptions for MC since it is treated as its own conduit. Think of it like inviting the neighborhood bully to a. Per National Electric Code (NEC), Class 1 and Class 2 wiring are not permitted in the same enclosure, cable, or raceway.
