Electrical draw by components
The maximum power available for your recreational vehicle depends on both the electrical
service you connect and the capacity of the converter/charger installed in the trailer.
The table below shows the typical electrical consumption for many appliances found in a
trailer, so you can determine the amperage you may draw at a given time.
If the total exceeds the amps available (30 amps), you cannot use all these appliances at
the same time.
The table below shows estimates for the various combinations of electrical feed.
