DROK AC Power Meter

When I built my house I installed a 100 amp emergency panel with select circuits that is fed from a 100 amp breaker via a Reliance 100/60 amp transfer switch. The 60 amp side/breaker is fed via a Reliance PB50 generator power inlet box. However, my generator actually uses a 4 prong 30 amp 240v outlet for which I have built a transition cord to the 50 amp power inlet box.

I decided to add some digital watt meters to monitor the two 120v legs of my generator power. I ended up choosing the DROK AC Power Meters because of the bright and high contrast display. This appeared more visual than the PZEM-061 LCD Display type meters. I will note that these digital power meters mention using pure sine wave inverters. My inverter generator has a pure sin wave inverter, so I cannot say if a standard portable generator would damage the meters.

I used a $10 plastic J-box (4”x4”x2”) from Lowes to hold the meters. The cover is too thick for the meter tabs to tightly hold the meters in place. But since there is no vibration, they basically hold in place well enough to work for this application.

So far I am extremely pleased with the results. I tapped the meter wires on the generator side of the transfer switch. The Current Transformers (CT) on the two hot legs with the corresponding power, and both of the other power wires to the neutral bar. It is my understanding that polarity is irrelevant. And looking at the wiring diagram, it appears that the CT wires should be facing the load side, so that is how I oriented them.

In this video, I show some un-narrated photos followed up by some real time videos.
