I suppose that I should have been more specific. What I intended to
convey was that I already have a heavy duty switch that cuts off the
power to the anchor circuit. I did not mean that I would use it as an
"up" or "down" switch. I was wondering whether I could use the breaker
as an on/off switch to control the power from the batteries

Thanks

Thanks for the clarification, Peter. It
really doesn't change anything though.
The point is that the more often you
switch a breaker on or off, the greater
the chance of failure. If you do it once
a week, the breaker may outlive your
boat. If you do it several times a day,
then depending on the breaker design and
a whole lot of other stuff, it may fail
before your boat does. Switches, on the
other hand, will usually sustain many
more operation cycles before failure.

Keep in mind that circuit breaker
deterioration and/or failure may not
even be evident in its use as a switch!
For all anyone knows, half the breakers
now in boats may not function in
accordance with their original
specifications. Who ever tests them?

For anything more specific, I think you
might want to consult Blue Sea.

In the end, it is all economics, broadly
defined.
