ARTICLE 393. LOW-VOLTAGE SUSPENDED CEILING POWER DISTRIBUTION SYSTEMS393.1 Scope. The heart of this system is a specially constructed suspended ceiling grid work system. The grid is engineered to simultaneously carry ceiling panels and support luminaires, while distributing a low-voltage power system to power luminaires and other utilization equipment capable of operating within Class 2 parameters. Current designs include T-bars that look much like conventional hung ceiling supports but with the power bus available on the very top of the inverted T (Fig. 393-1) to support LED drop-in luminaires that can operate on Class 2 limits, and …
