Hello,
I've just bought a portable 220V/5500W portable generator, and had it wired into my house panel as per the directions. It all works great, BUT I now wish I had a pair of wattmeters, to indicate the current load on each leg of the supply. (Ironically the generator manual recommends keeping both legs somewhat balanced with regard to load, but doesn't provide any gauges to help).
The expensive (and wasteful) way of doing this would be to buy a pair of clamp-on meters and hang them off the conductors.
What I would like to do is install a pair of wattmeters in an enclosure right at the panel. Getting 110V wattmeters with a range of 0-3000 shouldn't be that big a deal (right?). As for the sensors, a bit tricker.... An hour's worth of surfing indicates that I need things called donut-style Current Transformers (or CTs). These appear to come in an extensive variety of specs. I would have no idea which one to buy, how to wire it to the wattmeter, and what other components I would need?
Any suggestions or advice is welcome.
-many thanks.
