I recently bought a 2000 SCR 2700. It has two connections for shore power on the port side of the boat.
The electrical panel has two breakers labeled "Line 1 Dockside Master" and "Line 2 Dockside Master". On the Line 2 side, there is a sliding cover labeled "transfer" with another breaker under the cover on the transfer side.
I understand that I have to have power on line 1 to run the air conditioner or power connected to line 2 to run the battery charger, etc.
My question...what does the "transfer" switch do?
