Circuit breakers

I bought one from NAPA several years ago, it is a direct replacement for a standard fuse, and the come in several amp ratings.
 
For what it is worth ...

My thoughts on Circuit breakers:

Most of these breakers trip and reset after cooling.

1. Suppose that you have a short at night while car is in the garage:

2. The circuit breaker trips.

3. Breaker cools off and closes the circuit.

4. Breaker trips again.

5. Breaker cools again.

6. This continues until you find the problem if you are lucky.

7. If you are not lucky the breaker finally melts and fails in closed position and smokes the wiring most likely starting a fire.

Now if the circuit breaker has to be reset with a reset button you are much safer.

This hazard is not present with a fuse ... it pops and shuts off the current to the circuit!

What kind of circuit breaker?

Does it have a delay?
What overage can it tolerate and for how long?
Is it a fast one?

I am making a point. There are many types of fuses and circuit breakers for various situations. Some are designed to take a pretty good surge current before they trip other not so much. So you really need to consider the which breaker? What are the specs.

As I like to point out all too often, fuses and breakers are there to protect the wire from exceeding its current carrying and get hot enough to cause damage. A toaster does not pop a breaker, but sure can catch fire.

You also need to consider where the breaker is designed to work. Some really are not made for outdoors use and may not like being on a car.

Yes, I know people have 'successfully' done all sorts of stuff, that does not mean it is correct. It is not very uncommon for people to have a failure of the fuse holder make the car stop running or not start. Many who have fuses do not understand electricity so they have to call a tow. Truth is the A with a good harness does not really have electrical problems. Well that is until you start adding in some repro electrical parts it seems.

I use Bussmann circuit breakers that replace glass fuses and "Remains open for protection until trouble is corrected".

The resetting breakers are hand for troubleshooting. You can hear the click. Dive in and start wiggling to get that intermittent short to happen and you can hear it when it does. I agree that the resetting feature isn't so great for a permanent solution.
 
Thanks for all my good buddies .I think i'll pass on the automatic reset.I would like to know about a hand reset just like a home circuit breaker that will fit on the starter.

Thanks again

I use this type, manual reset.

On my 1992 Explorer, I kept having a fuse blow in the turn signal circuit. All attempts to find the problem failed. Finally replaced it with one of these circuit breakers and never had that problem again.
 
ive been using the reset breakers for years now with no trouble . I have more than one because I have many circuits in my car

That's the same as the bussman I use... Make sure it's installed properly... It has a BATT and a AUX side which is marked on it

Yes, That's the circuit breaker I was referring to in post #8 . And as Mitch said it is directional.

I have smaller one installed on the wire going to the light switch also also.
