User-upgradeable load control
A system is disclosed. The system may include a modular control unit configured to control power to at least one load device. The modular control unit may include a backplate with a recess that includes a set of backplate electrical contacts. The system may also include a contact element configured to receive the power. The system may also include at least one device control assembly configured to be removably coupled to the backplate. The device control assembly may include a set of device control assembly electrical contacts configured to electrically couple with the set of backplate electrical contacts of the backplate when the at least one device control assembly is coupled to the backplate and configured to electrically decouple from the set of backplate electrical contacts when the at least one device control assembly is decoupled from the backplate.
1. A system comprising:
a modular control unit configured to control power to at least one load device, wherein each of the at least one load device comprises at least one of an electrical load or an electrical receptacle from which electrical loads may be removably and electrically connected, wherein the modular control unit comprises:
a backplate comprising:
a recess that includes a set of backplate electrical contacts, wherein the recess is at least half of a total depth of the backplate;
a contact element configured to receive the power; and
at least one device control assembly configured to be removably coupled to the backplate, the at least one device control assembly comprising a set of device control assembly electrical contacts configured to electrically couple with the set of backplate electrical contacts of the backplate when the at least one device control assembly is coupled to the backplate and configured to electrically decouple from the set of backplate electrical contacts when the at least one device control assembly is decoupled from the backplate,
wherein the backplate further comprises an air gap actuator associated with the backplate electrical contacts, wherein the air gap actuator is configured to:
allow access by the at least one device control assembly to the set of backplate electrical contacts when the air gap actuator is in an open position; and
prohibit access by the at least one device control assembly and prohibit exposure of a user to the set of backplate electrical contacts when in a closed position.
2. The system of claim 1 , wherein the at least one device control assembly is configured to be removably coupled to the backplate via one or more fasteners.
3. The system of claim 2 , wherein the one or more fasteners include one or more screws.
4. The system of claim 1 , wherein the backplate, via the contact element configured to receive the power, is configured to be connected to live high voltage power from a main power supply of an electrical wiring system comprising a hot wire, and wherein the backplate electrical contacts are configured to supply the live high voltage power to the at least one device control assembly when the set of device control assembly electrical contacts of the at least one device control assembly are coupled to the set of backplate electrical contacts of the backplate.
