The difference between home and marine is the GFCI.
It is safer to use the marine even in an house:
""A GFI, or ground fault circuit interrupter, is an automatic device that offers personal protection against electrical shock. They are installed in areas where known electrical shock hazards exist... outdoor outlets and fixtures, swimming pools, saunas and hot tubs, outlets in kitchens, basements, bathrooms, and garages. Wherever there is the potential for contact between a person and an electrical appliance in or near moisture, water, or water pipes, a GFI should be protecting the circuit... and you!""
