Power Supply:
Different amperage supplies vary greatly in the amount of available current.
• The continuous amount of current through a breaker or fuse is only 80% of its rated
capacity.
• 50 Amp 240 Volt AC shore power service consists of two power supply conductors, a
neutral and a safety ground. The 50 Amp breaker simultaneously limits each power supply
conductor to no more than a short-term maximum of 50 Amps for each conductor. The 50
Amp 240 Volt service actually provides 80 continuous amps.
• Use care when hooked to anything less than 50 Amp shore service. Shore power service less
than 50 Amps consists of one power supply conductor, a neutral and a safety ground; 30
Amp shore service is limited to 24 continuous Amps; 20 Amp shore service is limited
to 16 continuous Amps.
Electrical Adapters:
There are many different electrical adapters to suit a variety of needs. Only UL approved adapters
should be used. The most common adapter is a 50-30 Amp adapter. The type of connector adapts the
50 Amp shore cord to a 30 Amp shore power outlet. Another common adapter is the 30-20 Amp
adapter. Always install the adapter to the cord prior to making the connection to the outlet.
