    Hi Robert,
    The following will need to be identified before determining the type and size electrical wire for this project:
    The specific electrical loads at the boat dock will need to be identified.
    The installation method that will be used to install the circuit, for example conduit or direct burial wire.

    Please refer to the Voltage Drop Calculator that I have provided on this website which will assist you further.
    I hope this helps,

    What grade of wire do I use to run 175ft from the outside GFI box on the house to the boat dock. I would have 4 flood lights and a 110 volt outlet for a battery charger.
