We’ve been on the road for nearly two months now and we’ve stayed at various types of sites: state parks with water AND electric, parks with water OR electric, full hookups with water, electric and sewer, and any of which would have 50 amp or 30 amp power connections. Although, we have not boondocked yet — look for a potential future post :)
When we’re connected to a 50 amp site, we really don’t need to give our electric usage much thought — not that we go hog-wild and run everything at once — but there isn’t a concern we’ll trip a breaker by going about our normal routines.
However, when we are connected to a 30 amp site, we found we need to be a little more mindful of our usage or else we trip a breaker. Which has happened a few times. Therefore we decided to calculate the amperage of all of our common appliances so we’d have a cheat sheet to refer to (we used this site for quick calculations).
Here are our common appliances and the amps they draw:
Rear A/C unit – 16 amps
Front A/C unit – 16 amps
Toaster Oven – 15 amps
Radiant Heater – 12.5 amps
Water Kettle – 12.5 amps
Rice Cooker – 5.6 amps
Exhaust Fan – 3.5 amps
Slow Cooker – 2 amps
Computer (Charging) – 0.7 amps
Radio – 0.25 amps
So when we are connected to a 30 amp circuit, we can have one A/C unit running but not both, and then the slow cooker and the rice cooker for dinner, but we can’t boil water for tea/coffee etc. There are also minimal draws happening in the background when phones are charging, refrigerator, lights, etc. so we factor in a few amps for the unknown.
It’s becoming second nature as to what we can run and when, but we always look forward to knowing when we have 50 amps to work with :)
