Watt Meter Box
2 Watt Meters for 7.5kW or 15kW Total

Don't operate your backup or alternative power electrical system blind!  Install this economical wattmeter box so you can see what is happening.  Perfect for monitoring generator load when your transfer switch or panel does not have meters.

Plastic enclosure for indoor or outdoor mounting comes with hinged front cover to protect the meters.  Cover is clear so that meters are visible without opening. Meters sense the power using current transformers (CTs) factory installed inside box.  Meter scales read in kW at 120VAC for each of two hot legs in a 120/240VAC system.  Made in USA  

For maximum meter life we do not recommend direct mounting of enclosure on engine driven generators due to vibration.  Mount separately on an indoor or outdoor wall.

This product uses non-contact donut sensors.  Current sensors each have a window opening for cable that is 0.35" diameter which will accommodate most #6 ga wire. Since the sensors and meters have no direct connection to the power system live conductors and operate at low voltage this product is not UL Listed and does not have to be.
