Can I upgrade to a 20 amp breaker?
You can upgrade your breaker to a higher amperage-rated breaker as long as the wiring in the circuit is of the correct gauge. A 12-gauge wire is required for a 20-amp circuit breaker.
Can I replace a 10a breaker with a 15a?
NO!!!!! The wiring is supposed to be rated to the breaker, which will trip if the load is too great (the breaker should be the weakest link in a circuit). If you change the breaker to a 15 amp (but leave the old wiring), the smaller wiring can overheat & cause a fire before the breaker trips.
Can you increase amps in breaker box?

How do I get more amperage?
In a circuit, cutting the resistance by half and leaving the voltage unchanged will double the amperage across the circuit. If the circuit's resistance remains unchanged, the amperage in a circuit can be increased by increasing the voltage.
Can I increase the size of my main breaker?
Remember breakers are sized according to wire size, unless you already have a mismatch between breaker and wire it's likely that you can't increase breaker sizes without re-wiring.
How do I upgrade my breaker amp?

Can You Upgrade A Circuit Breaker?
You can upgrade a circuit breaker to a new design circuit breaker as long as the new breaker will fit in the mountings in the breaker box and the breaker is rated for the same amperage as the original breaker.
Can I Install a 20-Amp Circuit Breaker on 14-Gauge Wire?
You can install a larger size circuit breaker on a circuit if the physical wiring is rated for the larger breaker. In many homes, the contractor who wired the house will use a lighter gauge wire for circuits that draw less current, such as the light circuits. The 14-gauge wire used for these circuits is easier to pull and is cheaper.
Can You Put a 20-Amp Receptacle on a 15-Amp Circuit?
15-Amp and 20-Amp are separate circuits and use different AWG wire sizes. Using the correct amp wire size is crucial. Let’s examine why.
