Up

The one thing I wish my whole-house standby generater came with was a power monitor. I would like to monitor the load it's driving when operational. Not finding what I wanted for a reasonable price, I decided to make my own. After scouring the 'net for some inexpensive meters, I found these. The hard one to find was the frequency meter. Fortunately, I found voltage and current meters to match. To keep it from using power all the time, I worked in a power switch. Now I know what load is going through my transfer panel, even when on utility power.
