Switching the power from the line (shore power – boats) to the inverter?
Important: If inverter is to be permanently mounted inside the vehicle (house or boat), a line switch is required to prevent damage to the inverter. Without this switch, 110 volts will try to enter the inverter as the inverter is trying to provide 110 volt output, (Assuming that the line is active). Have a qualified electrician install this switch. Line switches are available at any electrical outlet store. Note: Both the hot and the neutral of the plug must be switched! If not, damage to the inverter will result. Important: The AC ground and the DC ground can not be connected together! See grounding the inverter.
