The e.z. barrier eliminates the need for a manually built fire barrier around recessed lights to maintain the fire-rating of floor-ceiling assemblies. The box, which is designed to fit both 16-in. and 24-in. on-center applications with four knockouts for wiring flexibility, meets the specifications of 7-1 of the Uniform Building Code (UBC), Section 710 for Floor or Roof Ceilings. It can also be used as a vapor barrier for other openings.

The Ecostar is the world’s first hydrogen-fueled internal combustion engine-driven genset. Because the unit operates on pure hydrogen, the only carbon-based emissions are from a small amount of burned and unburned oil present in the combustion chamber. The engine is coupled to a Class H, 2-pole, brushless, self-regulating alternator with winding pitch designed to reduce the harmonic content of the output waveform. It’s capable of producing 91.2kW and 114kVA at 480V in 3-phase power and 75kW and 75kVA at 277V in single-phase power.
