Cambridge Fuse Question

Seem to remember from A&P school that a fuse is there to protect the
wire and not the component.

this is certainly true in an automobile because the cost of replacing
the wiring may be much more than the cost of replacing the component. In
sailplanes, the wiring is trivial to replace and I choose to protect the
expensive component instead.

When you protect the wiring, you are protecting the "expensive
component" - the glider! A wire fire is always exciting, as the smoke
creeps out around the edges of the panel... But practically speaking, a
fuse that protects the 302 will also protect the wiring, unless you are
using _much_ smaller wire than normal. I vaguely recall that the 302 has
an internal self-resetting fuse - a call to Gary K at Cambridge would
discover the truth.
