A multipurpose relocatable structure includes a floor system, a framework secured to the floor system, and walls coupled to the framework. The walls include a number of panels that are secured along adjacent vertical edges. The multipurpose relocatable structure may include a preconfigured interior, one or more doors having an emergency escape hatch, a protected electrical connector, an environmental control system that is configurable between operational and transport configurations, and lifting corners having securement apertures.

Some embodiments of the present disclosure are directed to a hybrid distribution unit that can distribute both power and data connections from a power and fiber cables (or from a hybrid cable containing both power and fiber) within a compact enclosure that helps reduce the overall footprint of the hybrid distribution unit mounted on a cellular tower. Some embodiments may also include circuit protection features, such as fuses or circuit breakers. Other embodiments may be described or claimed.

An automatic switching interface box for generators in residential dwellings and small commercial applications provides a breaker box transfer switch for generators powering one or more electrical loads. In power blackout situations, the breaker box transfer switch uses a power control relay to keep the load power on, which eliminates the need for a hot generator plug, because the plug in box is not powered. The generator power output cord is plugged onto the male plug of the interface box, or hard wired thereto. If the auxiliary generator had been started and is at rated voltage, the load is immediately and automatically switched from the utility connection to the generator as electrical source. The relay keeps the prongs of the male plug safely unpowered until the generator is attached since the relay coil is powered by the generator output and the plug is connected to the normally open contacts.

A circuit breaker and panel system includes a panel including a base pan having a plurality of base pan electrical connections. A circuit breaker including a housing having a plurality of circuit breaker electrical connections arranged to contact the base pan electrical connections when the circuit breaker is coupled to the base pan. The circuit breaker is rotatably coupleable with the base pan via a pivot joint for engaging the plurality of base pan electrical connections with the plurality of circuit breaker electrical connections per a predetermined electrical connection coupling sequence. One of the housing and the base pan includes a protrusion and the other of the housing and the base pan includes a corresponding recess which, when engaged with each other, retain the housing to the base pan to prevent reverse rotational movement of the breaker with respect to the base pan.
