Presumably the current it is rated at, i.e. 20 amps.
AIC stands for Ampere Interrupting Capacity, which is the maximum current the breaker can safely interrupt without damage. This rating is important for ensuring the breaker can handle and safely interrupt any potential fault currents in the electrical system.
The size of the main breaker depends on the maximum current rating of the 10 gauge wire and the load it will be powering. Typically, a 10 gauge wire is rated for a maximum current of 30 amps. Therefore, a 30 amp main breaker would be suitable for running 10 gauge wire. However, it is important to consult local electrical codes and consider the specific load requirements before making a final determination.
The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the breaker that is feeding it. In either case you must look for the manufacturer's label that will have the maximum current the panel can handle, make sure the breaker feeding the panel doesn't exceed this rating.
The breaker size for a TNIA-10 wire depends on the maximum current carrying capacity of the wire, which is typically indicated on the wire's packaging or in its specifications sheet. You should select a breaker that is rated slightly higher than the wire's maximum current capacity to ensure safety and avoid overloading the wire. It is recommended to consult with a qualified electrician for specific guidance on breaker sizing for your installation.
Oh, dude, you're hitting me with some electrical lingo! So, like, the Ampere Frame of a circuit breaker is basically the maximum continuous current it can carry without tripping, while the Ampere Trip is the current level at which the breaker will actually trip and shut off the circuit. Think of it like the frame being the "I can handle this much" and the trip being the "Okay, now I'm outta here" moment for the breaker.
The maximum current capacity of a 120 amp breaker is 120 amps.
The maximum current capacity of a 225 amp breaker is 225 amps.
The maximum current capacity of a 125 amp breaker is 125 amps.
The maximum current capacity of a 150 amp breaker is 150 amps.
The maximum current capacity of a 90 amp breaker is 90 amps.
The maximum current rating for the circuit breaker is 150 amps.
The maximum current rating for a 15 amp circuit breaker is 15 amps.
The maximum current rating for a 20 amp Murray breaker is 20 amps.
The maximum current capacity of a 100 amp circuit breaker is 100 amps.
The maximum current capacity of an 80 amp circuit breaker is 80 amps.
A 60 amp breaker can support a maximum current capacity of 60 amps.
A 50 amp breaker can handle a maximum current capacity of 50 amps.
