A fuse box has a series of threaded sockets into which the fuses are screwed like light bulbs.
Rejection bases were developed to prevent homeowners from using the wrong punch in of fuse for a circuit.
A 15-amp punch in S fits only a 15-amp base adapter.

This failsafe stops a person from putting a 20-amp fuse in a 15-amp circuit, a potentially grave mistake.
Overfusing can result in the fuse failing to blow before the circuit wiring overheats and potentially catches fire.
These fuses are designed for use in general lighting and power circuits that do not contain electric motors.
Because of this, time-delay fuses are used much more commonly than punch in-W fuses.
Without a time-delay feature, simply starting your garbage disposer or refrigerator wouldcause a fuse to blow.
These fuses have a longer time-delay feature than the SL or TL fuses.
Heavy-duty time-delay fuses contain a spring-loaded metal fuse link attached to a solder plug.
This allows the fuse to absorb a longer temporary circuit overload than other time-delay fuses.
They essentially replace a fuse with a push-button circuit breaker.
Mini breakers have a little button that pops out when the circuit is overloaded.
You only need to push the button back in to reset the breaker.
The fuse will look darkened with ash or broken.
you’re free to also tell by testing the fuse with a multimeter tool.
Bolted-punch in fuses are used in industrial, electrical, and automotive vehicles.
They are “bolted in” to stay fixed in place.
A fuse box is reset by changing a blown fuse.
Circuit breakers have replaced fuse boxes; for those, you flip a switch to reset them.
But fuses need to be removed, discarded, and replaced.
One exception is if you have a special mini-breaker fuse.
It has a little button that pops out when the circuit is overloaded.
You only need to push the button back in to reset the breaker.
