An assembly and method capable of preventing power interruption from a power supply that provides power through a cable to electrical equipment. The assembly includes first and second members, each having a base and a first extension projecting therefrom to define a recess. At least one of the first extensions has a channel defined therein in communication with the recess of its member. The assembly further includes features for orienting and securing the first and second members together such that their recesses cooperate to define a continuous interior cavity surrounded by the first and second members and the channel defines a continuous passage interconnected with the interior cavity. The interior cavity is sized and shaped to secure a power supply within the first and second members, and the passage between the first extensions is sized and shaped to secure a power cable to the power supply.
