An EVSE system includes an electric vehicle supply circuit having overcurrent protection circuit to prevent excessive current from flowing to the electric vehicle. A current limit may be set by a manufacturer of the EVSE, by a user of the EVSE, by an electric utility, by the EVSE itself in response to a control pilot signal, etc. The current limit may be set to prevent tripping an overcurrent protection device on a branch circuit for the EVSE, to accommodate one or more parameters of an electric vehicle charging facility, etc. The overcurrent protection feature may be integrated into a controller for the electric vehicle supply circuit, or it may be operate independently of the controller.

An EVSE system includes an electric vehicle supply circuit, and a timer adapted to automatically control the electric vehicle supply circuit. The timer may be adapted to enable and/or disable the electric vehicle supply circuit at one or more predetermined times. The timer may be coordinated with a scheduling system such as a calendar utility on a computer or portable communication device such as a smart phone. The system may include a user interface for the timer. The user interface may include an embedded server such as an embedded web server to enable a user to program the timer through the Internet.

A surge protection circuit utilizing direct current (DC) voltage on the information carrying coaxial cable of a receiving device with a surge protection device to suppress transient signal fluctuations over the coaxial cable and a diagnostic surge protection status indicator with on/off configurations to indicate the status of operation of the surge protection device. The visual indicator may be a light emitting diode or some other indicator device that when energized indicates normal operation of the surge protection circuit.

Multiple outlet receptacle

A power distribution unit includes a two pole circuit breaker having a first pole electrically coupled to an x-phase circuit portion of the power distribution unit and having a second pole electrically coupled to a y-phase circuit portion of the power distribution unit. The two pole circuit breaker is so designed that both of the two poles of the circuit breaker trip simultaneously and open even when an undesired electrical condition exists on the portion of the power distribution unit electrically coupled to only one of the poles.

A leakage current monitor device suitable for use in or with a Relocatable Power Tap. The device includes a leakage current detector circuit and an alarm circuit coupled thereto. The leakage current detector circuit is configured to detect leakage current from one or more loads connected to the RPT. The alarm circuit activates an alarm device when a detected leakage current exceeds a defined threshold.

Surge suppressor

A surge suppression circuit with a thermal cutoff includes a first surge suppressor in series with a first thermal cutoff device between a phase conductor and a neutral conductor. A second surge suppressor in series with a second thermal cutoff device is between the phase conductor and a ground conductor. A third surge suppressor is in series with a low temperature thermal cutoff device between the neutral conductor and the ground conductor. The thermal cutoff temperature of the low temperature thermal cutoff device is lower than the thermal cutoff temperature of the first thermal cutoff device.
