Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.

How do you read breaker box amps?
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.
How do you replace a 15 amp breaker in the circuit box?
To replace a 15 amp breaker, first shut off the main power to the circuit box. Then, remove the cover of the circuit box and unscrew the old breaker. Disconnect the wires attached to the old breaker, connect them to the new 15 amp breaker, and securely screw it in place. Finally, turn the main power back on to restore electricity.
How do you tell the difference between 100 amp and a 200 amp box?
You can typically determine the amperage of an electrical panel by looking at the main breaker. A 100 amp panel will have a main breaker rated at 100 amps, while a 200 amp panel will have a main breaker rated at 200 amps. Additionally, the size and number of circuit breaker slots can also be indicators of the amperage rating.
Why does the breaker in the main panel flip before the breaker in the spa box?
The breaker in the main panel typically flips first because it is designed to protect the entire electrical system of the house. The breaker in the spa box is typically more localized to protect the specific spa equipment and wiring, so it may have a higher tolerance before it trips.
If you have a 200A Meter Main Combo do you need a main 200A breaker in the panel?
When I went to a 100 amp service I could not find a 100 amp. breaker in stock. I used a 60 amp. breaker and have never blown it. The 200 amp you are using can handle up to 200 amps, but if you use a smaller breaker it will only handle up to that amperage. The 200 amp is usally the total amperage of all the breakers comming out of the box. You will probably never come anywhere near using 200 amps at one time.
What is the difference between a 100 amp breaker box and a 125 breaker box?
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
Can you downgrade from a 125amp main breaker to 100 amp breaker using the same box?
You can reduce the breaker size because that limits the current that can reach the main panel. There is no safety issue other than the significant danger in an unskilled person changing out a main breaker.

Is it ok to change a breaker box in a house from 2 fuses at 50amps to one at 50 and one at 35 amps?
Breaker boxes do not have fuses associated with them unless the main disconnect is independent from the breaker box. If that is the case both fuses have to be the same in the main disconnect that protects the breaker box.
Where is the outside breaker box located in relation to the main electrical panel?
The outside breaker box is typically located near the main electrical panel, but outside the building or house.
How do you replace a 15 amp breaker in the circuit box?
To replace a 15 amp breaker, first shut off the main power to the circuit box. Then, remove the cover of the circuit box and unscrew the old breaker. Disconnect the wires attached to the old breaker, connect them to the new 15 amp breaker, and securely screw it in place. Finally, turn the main power back on to restore electricity.
How can I wire a breaker box to another breaker box?
To wire a breaker box to another breaker box, you will need to connect the main power supply to the first breaker box and then run additional wiring from the first breaker box to the second breaker box. Make sure to follow all local electrical codes and safety guidelines when performing this task. It is recommended to consult with a licensed electrician for assistance to ensure proper installation and safety.
Is it unsafe to have 60A service going into a new electrical box designed for 100A?
Its not recommended because your new main breaker will allow up to 100 amps and your old wire can only safely handle 60amps. If you put a 60amp main breaker in the new box, that would be acceptable. No, it is perfectly safe. Because the box is overrated, there is no problem. If the box is the main panel, and not a subpanel, install a 60A main breaker so you cannot overload your service. If it is a subpanel this 60A breaker should be in the main panel.
When setting up a breaker box how do you determine circuit breaker capacity?
find amphere required
How do you tell the difference between 100 amp and a 200 amp box?
You can typically determine the amperage of an electrical panel by looking at the main breaker. A 100 amp panel will have a main breaker rated at 100 amps, while a 200 amp panel will have a main breaker rated at 200 amps. Additionally, the size and number of circuit breaker slots can also be indicators of the amperage rating.
Where is the garage breaker box located in the house?
The garage breaker box is typically located on a wall inside the garage, near the main entrance or on the wall closest to the house.
