Gardner Bender Power Usage Meter 125VAC 10A LCD 8.300

Power Usage Meter

The Gardner Bender Power Usage Meter plugs into a standard 125VAC outlet and measures the energy draw of connected appliances up to 10 A. It is designed for indoor use with air conditioners, computers, lamps, refrigerators and washing machines. The LCD screen displays consumption in kilowatt hours, matching the units used by utility companies. Homeowners and technicians can track running costs without specialised training.

Build Integration

The meter sits inline between the wall socket and the device under test, requiring no permanent wiring or panel modifications. Its IP20 rating limits it to dry indoor locations, so it must be kept away from moisture and dust. The unit logs data for up to 9,999 hours, freeing the user from manual recording during long-term audits. A maximum operating temperature of 50 °C means it should not be placed near heat sources or in unventilated enclosures.

Sustained Load Behaviour

Under continuous operation the meter maintains its stated accuracy while logging cumulative kilowatt hours over the full 9,999-hour window. The 10 A current rating is a hard limit; exceeding it will trip the protection and stop measurement. The LCD remains readable during extended sessions, and the internal logger retains data even if the monitored appliance cycles on and off. Users should verify that the total load stays within the rated current for the entire test period.
