So just how much more power does a 50-amp shore power plug have compared to a 20- or 30-amp plug? We like to bring a lot of our electronic toys with us, and have tripped the 30-amp circuit breaker a few times. Should we consider a 50-amp plug for our next RV? —Stan
It all comes down to watts. There are two basic numbers to consider when we want to calculate the wattage available from each style pedestal outlet: Volts and Amperes. Voltage is a measure of electrical pressure, and Amperes is a measure of available current flow. Ohm’s law tells us that Volts times Amperes equals Watts.
• 20-amp outlet = 2,400 watts
• 30-amp outlet = 3,600 watts
• 50-amp outlet = 12,000 watts
