Bill, by all means.
I'll give another example of this to expand the subject.
I recently bought a new VHF radio for installation in Grand Cru. In the package was a power cable with an in-line replaceable fuse. I've connected it to a switch on a Blue Sea DC Distribution panel that is at my Nav station that already has a higher current rated breaker than that rated for the fuse. The fuse goes in line after the breaker/switch to protect the radio. The DC panel is a standard commercial product with, I believe, a variety of breaker ratings (for a total of 45A) but the supplied fuse and in-line receptacle is that recommended and supplied by the accessory manufacturer. If it is in place and the radio fails and blows the fuse, you can clearly state to the manufacturer that it was protected using their recommended and supplied protection devices.
I have the same situation on a new RayMarine Quantum Radar connected to the same DC distribution system.
Breakers are fine if they are changed to reflect any change in technology or purpose for a circuit but it is often overlooked. A simple fuse that matches the rating defined by the accessory manufacturer, while not as convenient as a breaker, is invariably a better choice for equipment protection and for possible warranty claims later.
I'll restate the moral statement I used earlier:
The moral here is that changing ANY existing ELECTRICAL circuit technology OR PURPOSE has broader ramifications than you might think. It requires careful re-consideration of protection devices. Better to blow a fuse or breaker early than having something "sizzling" in a place you may not necessarily be fortunate enough to hear!
