Our distribution switchboards are provided with silver-plated copper or tin-plated aluminum bussing that is punched and tapped the entire panel length to accept any combination of bolt-on circuit breakers, motor starters or fusible switch devices. Cross bussing is extended for future additions by simply installing a short jumper bus between sections. Raintight NEMA 3R enclosures are supplied to fit the application. Welded formed steel frames and structures, and steel channel mounting bases are provided to ensure proper alignment of the switchgear as well as seismic stabilization. |
