The stores previously used individually mounted panelboards in a main electrical room, and a remotely mounted time clock to control lighting contactors. Further, floor-mounted UPS systems were used and set in place. Checkout, network, and other critical receptacles are required to have clean power, as well as a reliable backup source of power (UPS). The stores previously used loose panelboards in a main electrical room, and an individually mounted time clock to control lighting contactors. Further, floor-mounted UPS systems were used and set in place. Finally, HVAC controls were mounted on a separate board along with contactors to complete the system.
The Assembled Electrical Solution reduced the overall backroom footprint for the retail by more than 40%, and reduced the overall installation time by 30%.
The solution provided by Wesco was a result of working with the retail client and their prime design engineer. Assembled Electrical Solution assembly along with solenoid-operated smart breakers was used as a basic building block. One requirement was to reduce the size of the room, while maintaining system integrity. Integration of the HVAC controllers and UPS system were to be included. This eliminated the need for contactors and interposing relays for the lighting control scheme, and dramatically reduced the labor for installation because everything arrived pre-wired and tested at the site.
Custom, Compact and Cost-Effective
The HVAC controls are mounted in the assembly itself, and the time clock function is derived from the system controller, saving valuable wall space. The feeder panelboards are also integrated into the assembly. The MDP feeder breakers are factory wired from the breaker load side terminals to the panel main lugs and transformer lugs prior to shipment, further reducing the time and material required onsite for installation. The transformer is integrated into the unit as well as the UPS (providing clean power as well as system protection), further reducing the footprint.
Benefits and Savings
The Assembled Electrical Solution reduced the overall backroom footprint for the retail by more than 40%, and reduced the overall installation time by 30%. The smart breaker/time clock combination has allowed for smooth, energy efficient management of the lighting loads for the store, and pre-wiring of critical components (i.e., UPS) assuring a smooth startup.
