Circuit Breaker Specifications

Circuit Breaker Rating
Circuit breakers are used in place of fuses to protect an electrical device from a overload or short-circuit. Unlike fuses, circuit breaker do not need to be replaced whenever one "blows". Instead, simply flip the switch on the breaker and the connection is safely restored.

The circuit breaker rating is the number of amps that the unit has been rated at. The number of amps on a circuit breaker corresponds to the same number of amps needed when using fuses.

Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
Any Gauge with use of Ring Terminal AWG
Maximum Output Gauge Size
This number refers to the maximum size of wire that will fit into the output connector(s) of the capacitor, battery terminal, or any other connector with an wire output.

Best Answer: It's a little more complicated than just a simple answer, I'm afraid. There are three important factors in the related formula here: voltage (E), amperage (I), and wattage (W). The "formula" being E x I = W.
this product's limitation is in amperage (I), as are most circuit breakers. The limitation being 100 amps (I). What is needed for calculation is the voltage output of your car (which when running should be around 14.4 volts, and the wattage of your system. Let's say for instance you are wanting to install a 500 watt system. Also, let's assume you are operating at 14.4 volts. Rearranging the formula to determine amperage we get I = W/E, in this case, I = 500/14.4. Which would give us 34.72 amps. Now if you were wanting to run the same system while the car is OFF (which should be about 12.6 volts) you would be looking at I = 500/12.6, or 39.68 amps. So you see, the voltage is not really the limiting factor here. Do the math to determine the current required to support the system. The realistic maximum wattage of a system connected through this device, as we know the max current (100 amps), would be Watts = 12.6 Volts x 100 Amps, or 1,260 Watts. To give more cushion, I would cap it around 1,000 watts.

What size is the actual stud, and how much space is in between the stud and the plastic of the circuit breaker?
iAmGeranimo on Nov 24, 2014
Best Answer: Stud is about 0.230" (15/64), and is about 0.210" (13/64) from the breaker main body. Included are two 10mm (25/64") nuts with built-in 12.5mm (31/64") lock washers.
