To connect your vessel to shore power, a shore power pigtail adapter may be required. A pigtail adapter allows a vessel’s shore power cord to connect to marina power pedestals with a different plug configuration.
A typical pigtail adapter consists of:
- A male plug that connects to the marina’s shore power receptacle.
- A female connector that accepts the vessel’s shore power cord.
Why Pigtail Adapters Are Needed #
Not all marinas use the same electrical service. Shore power pedestals can vary by:
- Voltage
- Amperage
- Single-phase or three-phase power
- Pin configuration
- Regional electrical standards
Likewise, vessels may be equipped with different shore power connections depending on their size, electrical load, and country of origin. Using the correct adapter ensures a safe and reliable electrical connection while preventing damage to onboard equipment.
Important: Always verify the marina’s electrical service matches your vessel’s voltage, frequency, and power requirements before connecting. An incorrect adapter or incompatible power source can result in equipment damage, electrical faults, or safety hazards.
Common Shore Power Configurations #
The illustrations below show the most common pin configurations used for:
- Single-phase shore power connections
- Three-phase shore power connections
These reference diagrams can be used to identify the correct pigtail adapter required for your vessel and the available marina power supply.
