A power distribution box apparatus and method for implementing a priority disconnect scheme and a network communication bridge at a worksite, where the power distribution box distributes temporary power. The power distribution box includes a housing portion and a base portion elevating the housing portion off of the ground or another surface. The power distribution box includes a communication module having a network connecting module operable to connect to an external communication network (e.g., the Internet), and a wireless network module operable to wirelessly communicate with an external device (e.g., a smart phone) to, thereby, connect the external device to the external communication network. The power distribution box may also include a priority disconnect module to selectively disconnect AC output receptacles in response to over-current situations based on a priority level associated with each receptacle.
