Stop me if you've heard this before...
The breakers are there and sized to protect the wiring from melting and bursting into flame, not the electrical components along that wiring.
Electrical components must protect themselves, as their circuit designers are the only ones who know what the design limitations are.
Wires are slow to burn components, but electronics are quick to fry components.
The Snap-Action circuit breakers we use are slow to respond components to match wiring characteristics of slow to burn.
