I just installed a Reliance furnace transfer switch model TF151W to my main circuit panel. I tried to test it by running an extension cord from another outlet to the transfer switch. I put the P3 International P4460 Kill A Watt EZ Electricity Usage Monitor in the line to test the watt consumption of my hot air furnace.
After switching from Line to Generator and cranking up the heat, I noted the wattage was only 3.7 watts? Is this because the common neutral is not switched? If I was to connect the Honda EU2000I 2000 Watt inverter generator would I have any problems?
