Blue sea switch

[Mike2006]

Hi can anyone tell me what this blue sea switch (upper right in first picture) is for. I have attached a front side picture as well as backside picture. As you can see the switch only has one wire attached. At least I now understand why it appears to have no impact. Still I am curious what it is for. Thanks

Have you looked at what is at the other end of the red connected wire?

And... it's not grounded (no black wire) so whatever it's purpose before.... it ain't now. Prev owner probably left it so there wouldn't be a hole... and to drive next owner crazy.

Looking at the attached red wire to the back single side pole, the apparent diameter of the red wire and that the connector on the other side of the switch is open... I would be very cautious about not flicking the switch off and on.

The possibilities as to what is does can range from nothing here, now, to causing a power disruption in a parallel galaxy.

I would trace the red wire to its other end to identify where it is attached.

I just love a mysterious wire on a boat.

Do you have separate start and house battery banks? If not, we just figured out the reason

Big breaker (40 ampere), big wire.. The wire is attached to the "Load" terminal, so the input power would be properly tied to the "line" terminal, which is empty.. Maybe an (another?) air conditioner? It is close to the DC power switches, so something planned with a big DC load maybe?

Yes ,there are 6 house batteries and 1 start.

Agree... I will trace it back.

I will trace it back.

Carefully... Back away if you see that parallel galaxy... I recently watched Men in Black... That could open up a pandora box...

Advice taken!!!

Not a factory install, The red wire will only lead to the (+) supply line. The appliance it was serving was likely removed.

With new technology needing less power I found breakers no longer needed on our boat. Maybe you could add an ice maker or windlass.
