Blue Sea Systems is nimble and responsive to customers needs and changes in the marine electrical market. Blue Sea Systems uses tin-plated pure CDA 11000 electrical-grade copper where appropriate, rather than the lower cost brass alloys used by some manufacturers.

Just as electrical wire is always copper, so are the Blue Sea Systems products to which this wire is attached. Copper is 250% more conductive than brass. Electrical devices made with copper are capable of handling higher amperages at lower temperatures.
