That implies they can only provide one 120V AC leg, rather than two distinct 120V AC legs. However, most smaller generators are single-phase rather than split-phase. Your 120V, 50-amp RV, on the other hand, will be drawing the equivalent of 100Amps (2 x 50A legs) at 120V. So, at 240V, a 50-amp circuit may provide 50 amps, or 12,000 Watts (Watts = amps x volts, so 50A x 240V = 12,000W). The second 120V, 50A leg is used by the opposite half of your RV. The difference measured between them at their highest + or – voltage is 240V.ĥ0-amp Each 120V AC line provided at the pedestal is normally used to power a part of the outlets/appliances aboard.Īs a result, one 120V, 50A leg of the outlet is generally enough to supply half of your RV’s 120V AC electrical gadgets. The electricity that comes from your home’s outlets is sine-wave power, which means that the voltage cycles from +120V to -120V and back in a continuous curve called a sine wave that looks like this:Ī graph depicting two 120V AC power legs that are 180 degrees out of phase with one another. What does having electricity that is 180 degrees out of phase mean? That’s an excellent question! Remember that “AC” stands for “Alternating Current” in “120V AC” electricity. That implies there are two AC “hot” lines, each producing 120 volts of AC power and 180 degrees out of phase (measured with respect to the neutral, whereas measuring across the two hot legs would show 240V AC), as well as a common neutral and ground wire. What Is The Definition Of 50-Amp Power?įirst and foremost, 50-amp electricity, such as that provided at a camping pedestal, is split-phase.
#50 AMP GENERATOR GENERATOR#
Many 50-amp travel trailers and fifth wheels, on the other hand, do not have built-in generators at all.Īll of these people belong to a group of RVers who could consider using a portable 50-amp RV generator to augment their onboard power supply.Īs a result, we’re looking at the finest generators for a 50-amp RV today.
Others may have generators that have been neglected and have sustained significant, if not permanent, damage. However, many people purchase older Class A motorhomes, which may or may not have had a built-in generator. Do you need a lot of power? A 50-amp RV generator is standard on most big RVs, including ours.
