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 220 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 220 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 available 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.
