Re-Wiring my forecabin

[sailingbonbini]

Hey,

I've had a dodgy connection to my forecabin (36ft SV) so I've decided to pull a new wire. My question is: I would like to wire a couple of cabin lights and a fan in the forecabin in parallel, but don't want to pull cables all the way back to the control panel for each light/fan. How do I achieve this? Do I need a bus bar in the front, and then pull one cable from the switch panel to the bus bar, and then wire the individual consumers onto the bus bar? In that case I would need two bars, one positive and one negative, correct?

Thanks,
Tom
