Convert 120V to 12V
I Just got a macerator to empty tanks at home and am a bit stumped on powering it. I know I can pull right off the battery but am wanting to run it off my house/shore power. Reasons being I have two...

So, if wiring off the battery I'm seeing wire size recommendations from 8 to 14 gauge in the last handful of posts. Online I found some voltage drop tables but they talk about different % (3% table, 10% table, etc.). Does anyone have an opinion as to what table is used for the motor in this macerator? There seems to be a pretty big difference depending what table is used.
Something I did not know from a lack of DC wiring knowledge is the drastic wire size increase necessary when traveling distance. In houses it rarely is an issue unless pulling a feed to an outbuilding. Sometimes, with a very large house you might put a second panel at an opposite end. But I've often suspected the 2nd panel is as much about convenience for the electricians as it is voltage drop due to long runs.
