How do I increase the amperage of my circuit breaker?
The only safe way to increase the circuit’s capacity is by replacing the wire with one of adequate gauge. For 20 amps, 12 AWG copper is adequate for up to about 100 feet. If you simply replace the breaker, the wire can overheat and ignite the building from inside the walls.
What happens if you put a higher-amp fuse?
Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.
What happens if the fuse amperage rating is too low?
If the rating of the fuse is too low then it will frequently blow out even for a current value which is actually safer for the circuit. It should be optimum so as the remain the circuit closed for load currents below the permitted safe range and able to interrupt the circuit if the current exceeds.
Can I replace circuit breaker with higher amp?
You can upgrade your circuit breaker to a higher rating if the wiring is rated safe for 20 amps. A 20 amp circuit breaker must be wired with 12 gauge wire or larger. Otherwise, you may need fewer appliances using the circuit, or you may have a worn-out breaker that needs to be replaced with a breaker of the same size.
What happens if I use the wrong fuse?
Fuses are present to protect the components of the electrical system. Rather than destroying the circuit when there is a surge of power, the fuse blows to protect it. If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill.
What happens if you change the size of a fuse?
Altering the original fuse type or size or the circuit breaker size with a larger size will endanger the electrical circuit wiring and components. Up-sizing a circuit breaker or fuse will cause the circuit wiring to over heat. Overheated electrical wiring will create a serious fire hazard.
When do you need to increase the amperage of a circuit breaker?
The circuit breakers perform an important function in your home’s electrical system by protecting overloads in the wiring. There are instances when increasing the amperage of a circuit breaker in the breaker box is a good idea.
Why do you need a fuse or circuit breaker?
Notice: Installing additional electrical wiring should be done with a permit and be inspected. The purpose of a fuse or circuit breaker is to protect the electrical circuit wiring and components against overheating and electrical short or fault.
How big of a fuse box do I need for my home?
A small, 60-amp fuse box might be found in an older home that has not had its wiring upgraded. It can supply power to only one 240-volt appliance, such as an oven or a clothes dryer. Since most homes have more than one such appliance, this type of service panel is probably inadequate for a home of 1,200 square feet or more.
