In line fuses

Share this page

Keoke--

With all due respect I said that the fuse protects the wire--not visa versa.

Put simply, a fuse (or circuit breaker) is a sacrificial piece of the wiring or circuitry, its current-carrying capacity purposely designed to be less than that of the wire so that in case of an overload it will fail or trip and protect both the circuit and the appliance at its end.

I'm sure it has been done but I have never used two fuses and I like to place fuses as close as possible to the power source. One ca, btw, place a heavy fusible link between the battery and the fuse block or breaker panel, thus protecting all wires back to the battery itself.
 
IN some cases the wire acts as a heatsink sucking heat out of the fuse which prevents the fuse from blowing ,eventually the wire will melt the fuse remains in tact. Nasty problem
 
OK, ordered Charlie Hart’s fuse box, seems like a good start to me....
 
Going to individually fuse everything else.
 
Got the fuse box today, what a nice product!
 
The only wiring that I ever saw smoking and burning up on a Healey was the wiring on the firewall related to the overdrive circuit. Brand new cloth covered (over vinyl) wiring too. Ouch! Still not sure why that happened, but it and a few other things now have fuses.

Why didn't the car's designers include more fuses in the original design? (probably a rhetorical question)
