Shore Power Adapters
The Marinco
®
Shore Power Adapters give you more power hook-up flexibility and resolve a variety of dockside power center / boat
side inlet power incompatibility problems.
Types of Adapters
“Y” Adapters
let you split one dock side
receptacle between two boat inlets of
similar or dissimilar power
configurations. “Y” adapters are fully
molded and equipped with Marinco’s
unique sealing collar and covers (where
indicated) for use in wet locations.
The Reverse “Y” Adapter
(Item #
RY504-2-30) The reverse “Y” provides
50A 125/250V power when only two 30A
125V receptacles are available.
*Available with standard locking rings or
with the new EEL quick locking system
Straight Adapters
are high-quality,
one-piece adapters similar in usage to
Pigtail Adapters. However, they do not
have sealing collars and are not
recommended for use in wet locations.
Use only in an enclosed, dry location,
such as powering your boat from a 15A
power receptacle inside your house.
Pigtail Adapters
allow you to connect
from one dockside receptacle (or other
power source receptacle) to one
boatside inlet or equipment of dissimilar
power configuration. These adapters are
fully molded and equipped with
Marinco
®
’s unique sealing collar (where
indicated) and covers for use in wet
locations.
*Available with standard locking rings or
with the new EEL quick locking system
Pay special attention
to the differences in
the 50A 125V and the
50A 125/250V.The
blades look similar,
but they are different.
The plugs and
receptacles for these
systems are NOT
interchangeable!!
Check the blade
orientation of the
various inlets
pictured and
compare to your
boat inlet(s)
30A 125V
50A 125V
50A 125/250V
The voltage and
amperage
should be printed
on the outside
cover of your
existing boat
inlet(s)
The voltage and
amperage
should be printed
inside the boat

the blades
Notice the additional grounding blade on the 50A 125/250V inlets.

IMPORTANT 50 AMP INFORMATION:
If you are connecting to 50A dockside power
service, it is CRITICAL to know the dockside
receptacle’s voltage rating (50A 125V or 50A
125/250V). An adapter designed for 50A 125V
will not plug into a dockside receptacle rated
for 50A 125/250V service, and vice versa.
