Do boats have fuses?
Today, most boat owners have shunned the large fuse consoles that came in the 80s and 90s. A fuse box, or fuse block depending on the boat maker, connects the electronics aboard your boat to the power source, the battery.
What to do if your boat CANT connect to shore power?
Some marinas have developed test methods for determining if a ground fault condition exists within a boat prior to connecting the boat to the shore power network. For instance, Fort Pierce City Marina has a portable power pedestal with a GFP tester in it, and two at the fuel dock.
Can a isolation transformer connect to shore power?
The current that originates within the isolation transformer will never travel back to shore power. Isolation transformers may be a good solution to ground fault problems aboard your boat, and may offer additional benefits like correcting reverse polarization in the shore power and providing galvanic protection.
Why is my Dock pedestal breaker not working?
If the shore power pedestal breaker trips, the problem is likely an improperly wired transfer switch or inverter. If the dock pedestal breaker trips after an individual branch circuit breaker is switched on, it is likely the problem is a device connected to the breaker or defective control board in an HVAC or refrigerator circuit.
What are ground fault Breakers for a boat?
The updated code required ground fault protection to not exceed 100 milliamps of ground fault current leakage. Most marinas, however, have been opting to provide “ground fault for equipment” (GFEP) breakers at individual boat slips, which disconnects electricity to the boat at 30 milliamps of ground fault leakage.
Why do I have trouble plugging in shore power?
If you have had trouble lately plugging into shorepower, you are not alone. What used to be a relatively simple and reliable procedure has become a bit of a guessing game with new regulations aimed at reducing risk of electric shock, both to those onboard and those swimming near boats in marinas.

Isolation transformers may be a good solution to ground fault problems aboard your boat, and may offer additional benefits like correcting reverse polarization in the shore power and providing galvanic protection.
Where does the power come from for shore power?
For shorepower, the source is the power station somewhere onshore. Once electricity finds its way into the water it will seek a path through the water back to shore. If a path with less resistance becomes available, more current will flow into that path.
If the shore power pedestal breaker trips, the problem is likely an improperly wired transfer switch or inverter. If the dock pedestal breaker trips after an individual branch circuit breaker is switched on, it is likely the problem is a device connected to the breaker or defective control board in an HVAC or refrigerator circuit.
