Stern anchor windlass wiring

We are about ready to order our new stern anchor windlass cables. We are first getting the power (red) cable. This requires deciding on keeping this breaker below and fusing etc.

This picture is of a 2 gauge cable and a copper or bronze maybe strip and then a 40 AMP breaker and then a #10 wire and it goes to a buss which connects an old stern anchor windlass. We have purchased a spare windlass of the same kind and are replacing the old automotive 2 gauge cable with a new marine one. The other wires will be replaced also. This breaker is hard to get at berried under the cockpit deck.


This 2 gauge cable will be ordered 12' long with a 5/16 on one end and a ?? on the other.


After doing some research:
 The flat piece of metal is technically referred to as a "Bozocator", it confirms the presence of a Bozo during system design and installation. Probably kludged into place to prevent the larger cable lug from shorting out against the breaker's body, not a very elegant way to do it.


We will get rid of this little breaker and order our new cable. Then measure the full load and install a breaker by the nave station for the cable and windlass that will allow a bit of overload for the windlass. Also a fuse to protect the cable. 


We will get a clamp-on DC ammeter and measure the full load from the winch, then pick wiring and breakers that are proper for it. Breakers all allow a certain amoung of overload for a certain time, so we will select one that trips out before the winch can overload and overheat internally.
