A surge suppressor module includes a power conductor, a ground conductor, and a housing including an opening and a plurality of dovetail groove mechanisms and arcuate ground bus bars for electrically and mechanically mounting a corresponding surge suppressor module. An alternating current surge suppressor circuit is housed by the housing. The circuit receives the power and ground conductors through the opening of the housing. The circuit electrically connects the ground conductor to the plurality of arcuate ground bus bars for electrically and mechanically mounting a corresponding surge suppressor module, in order to provide a common ground connection thereto.

A surge counter/detector apparatus includes current sensors communicating with power lines to sense a surge condition. A trigger circuit communicates with the current sensors and outputs a first signal in response to the sensed surge condition. The trigger circuit is reset and enabled by a second signal in order to enable subsequent output of the first signal. A processor detects the first signal from the trigger circuit and responsively increments and displays a count value at a display. The processor provides the second signal having a first state to reset the trigger circuit and a second state to enable the trigger circuit. The processor includes a timer to vary a time between (a) detecting the first signal, and (b) resetting and enabling the trigger circuit.

Surge counter/detector apparatus, system and method

A meter includes an EEPROM storing a scaling factor; a divider providing a first analog voltage from an electrical system; an analog to digital converter (ADC) converting the first analog voltage to a first digital value; and a processor. The processor includes a first routine calculating the scaling factor; an input circuit for the first routine, and a second routine retrieving the scaling factor from the EEPROM and adding the scaling factor to the first digital value to provide a sum for a display. The first routine calculates the scaling factor by subtracting a second digital value from a larger third digital value, which represents a nominal voltage value. The second digital value is converted by the ADC from a second analog voltage from the divider, that receives a larger third analog voltage representing the nominal voltage value.

An outdoor enclosure for an electrical device includes a channel-shaped base plate, a five sided cover, and a flush-mount plate. The flush-mount plate has an opening that makes the front wall of the cover visible. The flush-mount plate allows the enclosure to be mounted flush indoors through a commercial building or a residential dwelling gypsum wall. The flush-mount plate has holes that are aligned with the threaded cylinders of the cover through which machine screws may pass to secure the cover to the flush-mount plate. The cover has no front flanges, and the bottom wall of the cover has slots, which allow the base plate to slide into the cover. The cover side flanges have holes and slots for side mounting. Additional side flanges that are bent from the top wall cover the upper parts of the side flanges of the cover, and prevent water from entering the enclosure from the top. A rear flange that is bent from the top wall prevents water from entering the top of the base plate. The cover top wall has a welded mounting plate for surface mounting. The channel-shaped base plate has holes at the bottom of its side flanges which are aligned with the holes of the cover side flanges. Machine screws pass through these holes and provide a way for securing the base plate and cover together. At the bottom of the base plate are slots for surface mounting.
