Our reliability record is superb reflected by our lifetime warranty on all products. Safeshore have now been supplying the marine industry for over 20 years. Safeshore models with monitoring also offer increased galvanic protection and easy testing of the installation. If the current flow increases beyond a preset threshold led’s will illuminate to indicate a fault condition. Units with status monitoring measure the current flowing through the isolator. What is the purpose of status monitoring? Realistically the higher the rating the more reliable the isolator. Usually UK marina supplies are either 16 or 32 amps so the isolator must be able safely handle at least 20% more than the maximum current available to comply with legislation. The isolator must be able to handle more than the available current supplied to the boat. Basically the amperage rating of the isolator is the amount of current the isolator can handle under severe fault conditions. No electrical knowledge needed… Just 30 seconds to install!ġ5 amps, 30 amps, 70 amps, 100 amps? What does it mean?Ī question we are asked all the time.

These units plug into the shore power leads either at the boat or the shore power pedestal of the marina. We supply excellent instructions and diagrams but if you do not feel competent to proceed we would recommend our “Plug and play” units.

The live and neutral cables of the shore power lead remain untouched. This is done by locating the incoming shore power lead, cutting the earth cable at a convenient point and inserting the isolator using terminal connectors provided. Internally fitted units are inserted into the incoming earth line between the shore power inlet socket on the boat and the consumer/distribution unit onboard. In the event of an electrical fault onboard the earth wire ensures the rcd / fuses/ breakers operate correctly and disconnect the mains electrical supply until the fault is rectified. If the earth cable causes the problem why not just remove it? In the event of an electrical fault onboard the isolator senses the fault condition and ensures your trips and rcd protection operate as normal ensuring safety onboard.

Job done! The isolator now creates a block for damaging galvanic currents minimising the risk of corrosion. This can be done internally in the boat or by using our plug in waterproof units you simply unplug the shore power lead from your boat, plug the lead into the isolator and re-insert the isolator flying lead back into the shore power inlet. We can protect against this problem by installing a galvanic isolator.Ī galvanic isolator is inserted into the earth line of the shore power lead. Unfortunately this pathway leads to increased corrosion of the underwater metals and results in rapid loss of anodes and increased pitting and deterioration of hulls, propellers, shafts, outdrives etc. This creates a pathway for small electrical currents to flow from one boat to another. When you connect your boat to a marina electrical supply you also connect your boat to all the other boats in the marina via the earth connection in your shore power mains lead.
