15 kVA 50A UL Listed Isolation Transformers - 60Hz

With a reputation as the shore power experts, Hubbell Marine offers a line of Isolation Transformers for the marine industry suitable for 50 and 100 Amp Shore Power Systems.
These UL Listed Isolation Transformers assure proper wiring conditions on your boat, and greatly minimize the possibility of stray current from entering the water.

They come as 15 kVA and 25 kVA models, 60-Cycle in White Powder Coated Steel and #316 Stainless steel.
International-rated (50/60 cycle) systems also are available, see Related Products.

Especially important on metal hulled vessels, but offering significant benefits for all boats, Isolation Transformers protect the metal fittings on any boat from potentially dangerous galvanic corrosion.
They do this by isolating the onboard AC sytem from the connected shore power AC system, while still maintaining the safety provided by the shore power AC green grounding wire.
