[C320-list] Circuit breaker ratings?

[Warren Updike]

Oh, Graeme, you are quite right, old boy. At my advanced age, it's not
unusual for my wires to be crossed. Thanks for the gentle course adjustment.

Not sure if we aren't crossed-wires here (no pun intended!)

On my panel at least (1996 vintage) the push on/push off breakers are only
on the AC side.

The breakers to which I was referring are the DC side, and only pop out when
the rating is exceeded.

I cant post a picture here, but if you cut and paste this link into a
browser its an image of a panel similar to mine

You can just see the black lines that show how each DC breaker links to
several different switches for different services.

Anyway I have decide to resolve the problem by using a 20Amp fused relay,
similar to this

but  fitted with a blade circuit breaker instead of a fuse.

The Nav/Com switch will run the low current 12v wire to the relay, which can
then switch on a dedicated supply protected by the 20A circuit breaker.

Plenty of room to fit this behind the panel and very inexpensive

If you have room to add a breaker, I recommend adding a 20 amp breaker.
