What is this?

Dear Captains,
While still trying to understand my boat, I foud this:



I wonder what is this for? Thank you very much.

It's your negative bus bar.

Connects together the -ve returns from various circuits and then runs them as one larger wire back to the power source.

Is it anode bonding?

A very tidy bit of wiring. Protect it from corrosion with a water repellent like clear Waxoyl comes in an aerosol can.

Thank you very much, Motor_Sailor.

Since this is a negative bus bar, then there must be a positive bus bar somewhere, right?

If I want to add some equipment or a new LED reading light, I don't need to wire all the way to battery but just connect to the +/- bus bars instead, right?

By the way, the bus bar in my photo seems to be full, is there any way to "expend" it if I want
to add new equipment?

Hi Stelican,
Are you suggesting me to buy a water repellent product such as Waxoyl and spray it on
the bus bar?

Not sure. I will go check next week.

Yes use it on all similar connections and aim some into the ends of the individual insulators where the actual wires enter. Brilliant stuff keeps verde gris away for years.

Ou can use the top bar by having the wire coming fro me above and use same pins,put label on wires so you know later in time what they are.

Thank you very much for all your information. Now I have better understanding about my boat.
