Yes, ACS/Uni-Fab is a UL Listed manufacture for Wiring Assemblies (QQYZ). This allows ACS/Uni-Fab to ship to the job site wiring assemblies with devices wired and ready for installation and trim out. Where contractors doing prefab in-house will need to leave devices out until after the inspector does their electrical rough-in inspection. This saves time and labor of multiple touches and allows for the contractor to bill the customer up to the trim out stage faster.
