Measuring electricity use
Hello, I'm not sure if this is the proper forum to post in, but I thought it was the most relevant area. I would like to know suggestions on how to measure electricity usage in a travel trailer ...

You want to find out what the KwH rate for the bill is, and you will want to know how many Kw you use in an hour.
Amps X Voltage = Watts (30A x 110V = 3300W = 3.3Kw So, if the rate is $0.15/kwh.....you would have about $0.50/hour = $12/day.....but remember, you don't use 30A anywhere near 100% of the time in a 24-hour day. The A/C isn't "on" 100% of the time (unless it's really HOT)
Exactly. To find the actual and current wattage, just get a small multimeter that has an AMP clamp. Clip it around the power cord and read the amount of current (amperage) being drawn. Using above math, you can figure out exactly how much power is being used at any given time.
Hope this helps
