NEW hardwired 50amp Power Spy™ now available!

50amp Power Spy™ #21 Hardwired Power Monitor allows you to add and monitor a 14-50 outlet's energy usage.  Now you can see exactly how much your electric vehicle charging equipment, or anything else equipped with an NEMA 14-50 plug is using for power. The beautiful four color meter tells you instantly what your line voltage is, your amperage draw is, your wattage draw is, and it even accumulates kilowatt-hours (kWh's). You can multiply the kilowatt-hours by your local electrical rate to see how many dollars and cents it cost to run your particular device. We pay approximately $0.125 per kWh here in Las Vegas.  The total is accumulated until you press the recessed reset button. The total is even held during power outages. This is a great solution to monitor the cost of operating any appliance. This unit is built with heavy duty terminal blocks for the power input capable of accepting up to 4 gauge wire and one side mounted 14-50 outlet.
