The exemplified systems and methods provide an extension cord system having a cord that is configured to slidably guide a movable plug carriage having conventional plug receptacle. In some embodiments, the movable plug carriage is configured with pierce-able conductors that can be inserted and retracted from a sealed skin of the cord. In other embodiments, the sealed skin can be fastened and unfastened by the movable plug carriage as the movable plug carriage moves over the cord. In yet other embodiments, the movable plug carriage is attachable and detachable from the cord.

Systems and methods provide an electrical bus plug on a busway, where the electrical bus plug is universal and configured to fit a plurality of busways. An adapter may fit on the electrical bus plug to allow the bus to properly electrically connect with the specific type of busway. Optional mounting brackets can also be removably attached to the universal electrical bus plug to permit attachment to a specific type of busway. Therefore, a single/universal electrical bus plug can be used to electrically connect to a plurality of busway types through the use of an adapter and mounting hardware that attached to the universal bus plug.

An example busway system is provided that includes a first busway, a second busway, and a joint seal coupling the first busway to the second busway. The first busway includes a first end and an opposing second end, and the second busway includes a third end and an opposing fourth end. The joint seal includes panels configured to at least partially slide over the first or the opposing second end of the first busway, and at least partially slide over the third or the opposing fourth end of the second busway to couple the first busway to the second busway. The joint seal creates a seal at a joint formed by the first busway, the second busway, and the joint seal.

A bus plug structured to electrically connect between a busway and a load includes a circuit breaker structured to electrically connect between connectors and the load and to output a first control signal, the circuit breaker including separable contacts structured to open to stop power from the flowing from the busway to the load, a motor operator structured to cause the separable contacts to open or close in response to the first control signal from the circuit breaker, and a wireless communication module structured to wirelessly communicate with an external device and to output a second control signal to the circuit breaker is response to wireless communication received from the external device. The circuit breaker is structured to output the first control signal to the motor operator to open or close the separable contacts in response to receiving the second control signal from the wireless communication module.

An electrical system includes an enclosure for housing an electrical device. The enclosure includes a door with an operating handle connected to a shaft when the door is closed, which can then be used to turn the electrical device on or off. The shaft rotation is further operable to simultaneously displace an interlock mechanism for engagement or disengagement to a busway structure.
