Re: Connecting 120V receptacles
The best reference I've found is Boatowner's Illustrated Handbook of Wiring by Charlie Wing. This includes the ABYC standards. If you don't follow the standards you risk a problem if you have an insurance claim or have a pre-sale survey done. Solder can't be the sole means of connection support you need a mechanical connection as well. Splice, butt, friction blade or bullet snap, terminals. You can stack up to four connectors per screw, and it seems without looking at it that would work if you have enough screw length, which you may not have.
If not there are three-way crimp butt splices, but I haven't used one. Wire nuts aren't allowed. I had a number of ground wires and made up a connection block to screw several wires to then has a wire going to the AC source Shore Power connector receptical. Except at the power source you can't have a connection between the neutral and grounding terminals if that's your set-u[. Should be in a waterproof enclosure, , screw and connector the same size, drip/tension relief loop.
