Prefab Electrical Assemblies

The competitive pricing of PowerWhip Prefab Assemblies enable electrical contractors to bid aggressively, winning more projects while increasing their margin and reducing installation time. With the improved installation efficiency, the electrical contractor can increase the volume of jobs it takes on, or take on more sophisticated, complex projects. PowerWhip Prefab Assemblies significantly reduce the time needed for installation of electrical assembly at the construction site resulting in 10%-15% savings of direct labor costs. This reduces the number of electrical contractor employees need to be present at the construction site, which in turn reduces congestion, lowering the risk of injuries and accidents, theft and loss of materials and tools, and reduction in exposure to overall general liabilities. PowerWhip Prefab Assemblies are ideal for electrical projects such as condominiums, hotels, motels, health care facilities, hospitals, rest homes, and dormitories and are NEC compliant and UL listed.
