A multiple chamber explosion proof device may be configured for use in extreme environments. The enclosure includes a plurality of chambers in which a first chamber may contain equipment and at least a second chamber may be configured with other equipment. Between each chamber is an explosion proof bulkhead with thread connections used to mitigate flame paths. Each bulkhead may include access ports to allow electrical and network connections to be passed through the bulkheads. The wiring may be explosion proof. A cap for the terminal end includes threads to be secured to second bulkhead or another bulkhead and seal the enclosure. When the cap is removed, access to electrical connections for the device is provided.

A lighting system has a plurality of central-control devices and a plurality of groups of local light-control devices. The central-control devices are electrically connected in a first daisy-chain form. Each group of local light-control devices are electrically connected in a second daisy-chain form. Each group of local light-control devices are connected to one of the plurality of central-control devices.

An electrical power or electronic data unit includes an outer housing and an inner housing that is insertable into the outer housing. The outer housing has an outer front face panel defining an outer receptacle opening and the inner housing has an inner rear housing portion plus an inner front face portion defining an inner receptacle opening aligned with the outer receptacle opening. A circuit board substrate is positioned inside the inner housing with an electrical contact mounted to the board substrate and aligned with and accessible through the inner and outer receptacle openings. A contact support extends rearwardly from the inner front face portion adjacent the inner receptacle opening, the contact support serving to limit movement of the electrical contact during insertion of a plug or prong into engagement with the electrical contact.

An electronic module is provided with a housing with an inlet to conduct alternating current (AC) power and an outlet to conduct direct current (DC) power to charge a vehicle battery, the housing defining a cavity. A circuit board assembly is supported within the cavity to convert the AC power to DC power. At least two power distribution wires are connected between the circuit board assembly and the outlet. A base is supported by the housing and extends between the at least two power distribution wires and the circuit board assembly to shield the DC power from electromagnetic interference generated by the circuit board assembly. A plurality of walls extend transversely from the base and are spaced apart from each other to define at least two channels, each channel is sized to receive one of the at least two power distribution wires.

A telecommunication system powers and distributes a signal within a telecommunication network. The system includes a cable distribution assembly includes a housing defining an interior. The housing includes a body and a cover configured to provide access to the interior. The cover includes at least two connectors. The cable distribution assembly includes a splitter coupled to the cover. At least two distribution cables each extend between a first end and a second end. Each of the first ends are coupled to the splitter. Each of the second ends of the distribution cables individually correspond to, and are connected to, the connectors. The splitter, the at least two distribution cables, and the at least two connectors are continuously coupled to the cover when mounted to and removed from the body. A trunk cable assembly includes a power cable connected to the splitter and communication cables connected to the connectors.

A power adapter configured to provide power to a load is described. The power adapter comprises a first plurality of contact elements comprising a first contact element configured to receive power and a second contact element adapted to be coupled to a load; and a surface adapted to receive a control attachment and comprising a second plurality of contact elements; wherein a third contact element of the second plurality of contact elements is configured to receive power by way of the first contact element of the first plurality of contact elements; and wherein power is applied to a load by way of the second contact element of the first plurality of contact elements.

Electrical box assemblies and electrical box separators are provided. The electrical box assembly includes a box housing having four sides and a bottom and a box separator secured within the box housing and configured to create at least two isolated compartments within the box housing.

A wall-mounted assembly may include one or more host devices which receive line voltage and generate low voltage power on one or more contacts for powering one or more modular devices. The one or more modular devices may be installed adjacent to the host device and may share a faceplate with the host device, such as a standard decorator faceplate. The modular devices may receive power from the host device via a power bus between the host device and the one or more modular devices. Further, the power bus may include a communication bus for communication between the host device and the modular devices. The faceplate may be a smart faceplate, which may include circuitry, such as a battery backup, occupancy sensing, a charging dock for a mobile phone, etc.
