摘要:
A system includes an electric vehicle supply circuit adapted to supply electric power to an electric vehicle, a line fitting arranged to connect the electric vehicle supply circuit to a source of electric power, and a sensor arranged to detect when the line fitting is being disconnected from the source of electric power. The electric vehicle supply circuit is adapted to interrupt the supply of electric power to the electric vehicle in response to the sensor to interrupt the flow of power through the electric vehicle supply circuit before the line fitting is disconnected from the power source.

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.

Resettable circuit interrupting devices, such as GFCI devices, that include reverse wiring protection, and optionally an independent trip portions and/or a reset lockout portion are provided. The reverse wiring protection operates at both the line and load sides of the device so that in the event line side wiring to the device is improperly connected to the load side, fault protection for the device remains. The trip portion operates independently of a circuit interrupting portion used to break the electrical continuity in one or more conductive paths in the device. The reset lockout portion prevents the reestablishing of electrical continuity in open conductive paths if the circuit interrupting portion is non-operational, if an open neutral condition exists or if the device is reverse wired. Methods for ensuring a reset lockout state before shipment are provided.

The power strip of the present disclosure includes an arc fault circuit interrupter (AFCI) to interrupt power to electrical devices plugged into the power strip when arcing is detected and, when combined with a transient voltage surge suppressor (TVSS) device and/or a ground fault circuit interrupter (GFCI) also can provide transient voltage surge suppression and ground fault protection. The power strip here disclosed can include an AFCI by itself or an ACFI in combination with a GFCI.
摘要:
An arc fault circuit interrupter (AFCI) device functions to provide protection from potentially dangerous arc faults. The arc fault detector can be used stand alone or in combination with circuit interrupting devices such as IDCIs and ALCIs. The AFCI device detects both AC line frequencies and high frequencies associated with arcing. Both average and instantaneous values of both AC line frequency and high frequency arcing signals are processed to generate an arc fault signal. The trip mechanism of the device trips on the occurrence of either an arc fault or a ground fault. The device allows the arc detector to differentiate between destructive high level arcing and low level arcing such as generated by typical household appliances and equipment. This serves to decrease the occurrence of false tripping. The device also includes a timer circuit, which permits the user to temporarily disable the arc detector, and includes communication means to permit the device to communicate the occurrence and location of the arc fault to a centralized monitoring station.
摘要:
An extension cord having a male plug at one end and a receptacle at the other has a mechanism for opening the phase and neutral conductors in the event the receptacle is subjected to a conductive media. A recess in the face of the receptacle receives a first immersion detection electrode and a spaced, parallel, second immersion detection electrode. A conducting media bridging the two immersion detection electrodes sends a signal to an operating device which causes the opening of the phase and neutral conductors until the conducting media is removed.
摘要:
The present invention relates to a family of resettable circuit interrupting devices that avoid reverse wiring conditions by sensing which pair of two pairs of terminals on the circuit interrupting device is connected to a source of electricity and connecting the pair of terminals sensed as line terminals to the circuit interrupting device as the line terminals and the other pair of terminals as the load terminals.
