Electrical distribution system including micro electro-mechanical switch (MEMS) devices

An electrical load center comprising:

• a main housing including a plurality of walls that define an interior portion;
• a bus bar extending within the interior portion of the main housing;
• at least one circuit breaker device electrically coupled to the bus bar, the at least one circuit breaker including an electrical interruption system having an electrical pathway, at least one micro electro-mechanical switch (MEMS) device electrically coupled in the electrical pathway, at least one hybrid arcless limiting technology (HALT) connection, and at least one control connection;
• a HALT circuit member electrically coupled to HALT connection on the circuit breaker device;
• and
• a controller electrically coupled to the control connection on the circuit breaker device, the controller being configured and disposed to selectively connect the HALT circuit member and the at least one circuit breaker device via the HALT connection to control electrical current flow through the at least one circuit breaker device.

A method of controlling an electrical circuit in an electrical load center, the method comprising:

• signaling a circuit breaker device having at least one micro electro-mechanical switch (MEMS) device to pass an electrical current through an electrical pathway to a bus bar of the electrical load center;
• closing a hybrid arcless limiting technology (HALT) switch to pass a signal to the at least one MEMS device;
• switching the MEMS device to conduct the electrical current through the electrical pathway;
• sensing an undesirable current parameter of the electrical current;
• opening the HALT switch to cut off the signal to the at least one MEMS device;
• and
• switching the at least one MEMS device to open the electrical pathway.
