User-upgradeable load control

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.
