System and method to derive power and trip a circuit breaker from an external device

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.
