The other factor is that a receptacle that is weathered or burned will consume power just to push through the resistance of the connection and that also is part of the load that your RV draws. That is because circuit breakers are designed to get weaker as they age, just to be sure that they won't go the other way so each time one trips is requires just a tiny amount to make it trip the next time so you may not have the full 30A it is rated at. But there is another factor that enters into the mix which you can't control and that is condition of the circuit breaker on the power pedestal as well as the condition of the power receptacle that you plug your RV into. You can usually look on a tag near the power cord and it will either give the amps needed or the watts which you just divide by 120V to determine amps. Your typical TV set today will need about 3 - 5A if on 120V.Īny appliance that uses heaters like an electric fry pan or slow cooker can be expected to draw about 6 - 10A. (Watts = amps x volts or amps = watts/volts) An electric heater will draw about 12.5A if on high and 6 - 7A when on low. Most RV microwaves are of about 800 watts which means about 7A. Most RV air conditioners will draw somewhere between 8 to 13A, depending upon how large the unit is and how clean the coils are. The refrigerator draws only a couple of amps as does the water heater and both require the 12V supply even if operating on 120V-ac because the temperature controls all operate on 12V-dc. Your slide outs usually draw a lot but only when moving in or out. The largest 12V-dc load in most RVs is the furnace blower, but you might have a few other big ones. In other words, to supply 30A-dc power your converter will use just a little more than 3A-ac 120V. You can get an idea of what it may need by estimating the 12V current draw and divide that by 10. If batteries are full and you are not using the furnace or some other large 12V load, the typical draw is probably less than 5A.
