That's my plan until I get my progressive Industries electrical management device next year that will give me constant amp readings, then I'll know what my cushions are on each appliance and electronics.

Certainly an EMS will provide power draw measurements but so to will an inexpensive Kill-a-Watt Meter. Rarely will an electric heater labeled as "1500 watts" actually draw anywhere near that ... I've got several and they range from ~ 950 watts to ~ 1400 watts on the highest setting. Measure what you have and you'll know, not just be guessing. ;)

Yes.. I plan to measure them with the EMS I am getting for Christmas. . The main reason for wanting the EMS rather than just the surge protector I currently have is to prevent damage to my TT systems from all the frequent low voltage situations I am reading about from Rv'ers that can wreck or shorten the life of my AC compressor, microwave and electronics.
While an EMS certainly serves a valuable role in protecting your trailer's electrical system it's ability to monitor & display various parameters is limited, particularly current draw which is only accurate to the nearest ampere ... the Kill-a-Watt's current draw resolution is in hundredths. Yes, an EMS will monitor incoming voltage but a Kill-a-Watt will also measure power in watts, power factor, and volt / amps - none of which the EMS is designed to do. Bottom line - while you're waiting for Santa invest $20 in a Kill-a-Watt that will tell you a lot more about your electrical devices than any EMS. ;)
