Abstract
A method for enabling an ETU to function as a host controller is provided. The ETU includes a power bus port, a current sensor input, and a power distributor coupled to the power bus port and the current sensor input. The method includes determining that a peripheral device is connected to the power bus port. The method further includes determining that sufficient input power is available to the ETU to provide an output power to the peripheral device through the power bus port. Additionally, the method includes providing the output power to the peripheral device through the power bus port.

A method for enabling an electronic trip unit (ETU) to function as a host controller, the ETU including a power bus port, a current sensor input, and a power distributor coupled to the power bus port and the current sensor input, said method comprising:
- determining that a peripheral device is connected to the power bus port;
- determining that sufficient input power is available to the ETU to provide an output power to the peripheral device through the power bus port;
- and
- providing the output power to the peripheral device through the power bus port.
An electronic trip unit (ETU) configured to function as a host controller, said ETU comprising:
- at least one current sensor input;
- a power distributor coupled to said at least one current sensor input;
- a memory;
- a processor coupled to said memory and said power distributor;
- a power bus port coupled to said processor and said power distributor;
- said memory comprising processor-executable instructions that, when executed by said processor, cause said ETU to:
- determine that a peripheral device is connected to said power bus port;
- determine that sufficient input power is available to said ETU to provide an output power to the peripheral device through said power bus port;
- and
- provide the output power to the peripheral device through said power bus port.
A system for monitoring and diagnosing errors in an electronic trip unit (ETU), said system comprising:
- an ETU comprising a power bus port;
- and
- an ETU diagnostic device connected to said power bus port, wherein said ETU is configured to provide power to said ETU diagnostic device through said power bus port only upon a determination that sufficient power is available to said ETU to sustain operation of said ETU and said ETU diagnostic device.
