How to Increase Amps in a Breaker Box
- Consult with a qualified electrician before increasing the size of a circuit breaker. ...
- Turn off the power to the circuit breaker box at the disconnect box. This is usually located by the power meter.
- Remove the outer panel of the breaker box by removing four screws from the cover and pulling the metal cover off.
- Firmly pull the circuit breaker out of the box; no tools are necessary, just give it a firm pull.
- Take the circuit breaker to an electrical supply or home improvement store and buy the same type of circuit breaker in the correct amperage.
- Push the new breaker into the box by pushing it firmly in until it's seated in the box. Replace the panel and turn the power back on.

How to increase breaker amps?
To increase circuit breaker amps, you will need to upgrade the wiring in your home to handle a greater amperage load. A 14-gauge wire is sufficient to handle 15 amps without overheating. To increase your circuit breaker amps, you can either have an electrician rewire your home or add a new circuit. The only way to increase ...
How to increase amps in a circuit?
The only way to increase the amps delivered by a circuit in your home is to ensure that the wiring in the home can carry the amperage. In most instances, this is a job best left to a professional and licensed electrician.
What Are Amps?
Amps, or amperage, is the measurement of how much work and electrical circuit can perform. In most homes in the US, the standard for electrical service is 15 amps at 120 volts. This standard home electrical circuit uses 14 gauge wire as a standard.
What is the amperage rating on a service panel?
The amperage rating on your service panel is typically the same amperage that your utility company provides. Most homes have a 100 amp rated service panel. If you add circuits or increase the amperage of circuits, you may exceed the rating of your service panel.
What is a circuit breaker?
Breakers – The Valve that Protects the System. Circuit breakers work like safety valves. If the demand exceeds the amperage rating of the circuit breaker, the circuit breaker opens to protect the electrical system. The circuit breaker interrupts the flow of electricity in the circuit. As an example, a normal 15 amp household circuit can deliver ...
How many watts does a 15 amp circuit breaker deliver?
The circuit breaker interrupts the flow of electricity in the circuit. As an example, a normal 15 amp household circuit can deliver about 1800 watts to the circuit. If you plug in a 1500 watt hairdryer and a 1500 watt toaster on the same circuit, the circuit breaker should open. You have asked the circuit to provide 25 amps on that circuit.
How many amps does an electric company need?
Many urban electrical utility companies only provide 100 amps of service to most customers. If your utility company can only provide 100 amps to your home, you must add up the total amperage required to service your home as currently exists.
Why change the size of a circuit breaker?
Changing the size of a circuit breaker to increase the available current is a great way to burn your house down, melt an outlet or ruin an appliance. The circuit breakers in your home's service panel are designed to prevent dangerous current overloads. A circuit breaker is sized to match the amount of electricity the wire can safely carry.
What is a circuit breaker?
A circuit breaker is sized to match the amount of electricity the wire can safely carry. If you are having trouble with a circuit breaker that is constantly tripping, the circuit is either overloaded or has other problems.
How to remove a wire from a breaker?
Loosen the clip holding the wire to the breaker with a screwdriver and remove the wire.
What happens if you use a breaker that is too large?
Using a breaker that is too large for the wiring can cause property damage, injury or death.
What to do if the voltage tester does not read zero?
Test the voltage inside the panel. If the voltage tester does not read zero, check the main breaker again.
How to turn off power to service panel?
Turn off the power to your service panel by shutting off the main breaker.
How does amperage increase?
Increasing the amperage in an electrical circuit is done by removing or reducing the amount of resistance that the voltage in the circuit encounters.
How to increase voltage and decrease resistance?
Increasing the voltage and decreasing the resistance in a circuit nearly always involves rewiring the entire circuit unit.Rewiring a circuit requires turning off all power to the circuit breaker. Once all outlets have been disconnected from the power source, you will disconnect the switch plates associated with each outlet wired to that particular circuit breaker. After cutting the existing wires, you'll replace the wires, the outlets and the circuit breaker with ones that have a higher amperage rating (make sure that they all have an equal amperage rating). An employee of the hardware store should be able to help you select the correct wire for the amperage rating.
What is an ampere rating?
An "ampere rating" describes the amount of amperage that wires, breakers and other attendant devices can support. If your circuit contains chips known as resistors, you can lower resistance and therefore increase amperage by switching out the current resistor for a one with a lower rating.
Can you replace wires after cutting existing wires?
After cutting the existing wires, you'll replace the wires, the outlets and the circuit breaker with ones that have a higher amperage rating (make sure that they all have an equal amperage rating). An employee of the hardware store should be able to help you select the correct wire for the amperage rating. Advertisement.
Why are circuit breakers important?
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.
Can you work on a live circuit?
Don't attempt to work on a live electrical circuit. Seek help from a qualified electrician if you're not comfortable doing this job.
How to add amperage to a circuit breaker?
Add their amperages together. If the result is more than 80% of your circuit breaker's rated amperage, plug one of the devices into an outlet on a different circuit.
How many amps does a circuit breaker need?
In the United States, standard household circuits are rated for 15 or 20 amps. Specific appliances may need dedicated, high-load circuits for 30 or 50 amps.
What happens when a circuit breaker is overrated?
When that amperage is exceeded, the circuit breaker shuts down the flow of current in that circuit to prevent damage to the wiring and appliances. Learn how to calculate the actual amperage of devices on the circuit and compare it to the rated amperage, so you can avoid unnecessary power interruptions and fire hazards.
How to calculate amps from wattage?
Divide the wattage by the voltage. The answer will be the amperage the device draws on your circuit. For example, a 150-watt device on a 120-volt circuit will draw 150 ÷ 120 = 1.25 amps.
How many volts does a 2 pole breaker supply?
For example, a two-pole breaker at 15 amps on each pole (breaker handle) would supply 240 volts to the appliance on that branch at up to 15 amps, not 30.
What is the breaker size for a continuous load?
Breakers should be sized at 125% for a continuous load and 100% for a non-continuous load, which comes out the same when you multiply the breaker size by 0.8.
What is a plug in watt meter?
You plug it into a receptacle, then plug an appliance into the watt meter to directly read how much power it is using, as displayed on the meter. This may not provide a convenient branch-circuit total load, but it avoids the risk of trying to use a clamping ammeter on live wires inside a breaker panel.
