Description
Blue Sea 1208 AC Source Selector Switch | Boat Supply Store
This robust selector switch facilitates the safe management of dual 120V AC power sources aboard vessels, such as shore power and onboard generators, preventing simultaneous energization of both inputs. It offers a 30A rating per pole and includes essential safety features like red 'Reverse Polarity' LEDs and green 'Power Available' LEDs to confirm source status. The unit's physical lockout slides ensure that only one source can be selected at a time, minimizing the risk of critical electrical faults. With dimensions of 4.75" H x 4.88" W x 3.00" D, it provides a compact yet effective solution for power distribution on cruising yachts or sportfishing boats operating with multiple AC feeds.
