What else can I help you with?
Can double pole circuit breakers be changed into single to create more room in the pannel box?
No, double pole circuit breakers cannot be changed into single pole breakers. The breakers are designed for specific functions and changing them can create a safety hazard. If more space is needed in the panel box, consider upgrading to a larger panel box or rearranging the circuits to free up space.
Can you use mini breakers instead of regular breakers?
Yes, but only use them if absolutely necessary and I would never install more than one set of min-breakers in a service panel. Otherwise you can overload the panel.
How many 50 amp breakers feeding 50 amp outlets can you install from a 125 amp main panel?
Three or four would be normal. The total current should not exceed the rating of the main panel, so depending on how intensively the different circuits are used, more could be installed.
What is the max number of breakers in a breaker box?
Some local electrical codes don't allow mini breakers, so check with local codes before you install them. As a general rule the total load of all breakers should not exceed the supply load of the main. As a general rule the total load of all breakers should not exceed the supply load of the main. This is not a true statement . You will find that if you add up all the breakers, in most cases the total will exceed the main breaker total. On a 42 circuit board at 15 amp breakers the total will come to 630 amps. The way code looks at it is that not all circuits will be on at once and not all at full load. The main breaker only protects the service entrance wires. If the amperage of the main service wires becomes greater than that of the wire rating then the main breaker will trip.
Is it safe to have 200 plus amps in breakers inside than 90 amps on the main service breaker outside?
I am assuming by your description that the panel is protected by a 90 amp breaker and the breakers in the panel when added up is 200. This is okay as long as your 90 amp breaker trips on a regular basis. It is typical for the breakers to add up to more than the main breaker under the assumption that you would rarely be running each circuit at its maximum capacity.
Have existing a 125 amp main need more breakers spaces?
You can swap a single breaker for two mini breakers or you can add a sub-panel. If you only need a couple of extra circuits then just add mini-breakers.
Can you load an electrical panel with only 20 amps?
If you mean can you put a single 20 amp breaker in an electric panel, the answer is yes. An electric panel is typically made to handle more breakers with values that add up to more than the rating of the panel on the supposition that you will never draw full load on all breakers. If you do the main breaker would trip. In your case you are under utilizing the panel, but this is not a problem.

What is the formula the breakers in panel?
There is no formula used to fill a distribution panel. The panel is loaded according to the circuits that are to be connected to it. After you have determining what breakers are needed always buy a distribution panel that has more slots than you need. The extra cost of buying a panel with more slots in it will pay for itself in the future if additional circuits need to be added.
Why does the main circuit breaker trip but not the smaller branch circuit breakers?
If the main breaker has ground fault detection, and the fault is a ground fault, then only the main may trip. Also if the fault is a direct short, the fault current may be several thousand amps, much greater than the trip point of both breakers. Breakers have an I^2T curve (current squared-time), which is an indication of how fast the breaker will trip at a given overload. When both breakers are overloaded, the breaker with the faster I^2T rating at that current level will trip first. This would be an indication that the breakers are improperly specified or adjusted.
What is a sub panel and how does it function within an electrical system?
A sub panel is a smaller electrical panel that is connected to the main electrical panel in a building. It helps distribute electricity to specific areas or appliances within the building. The sub panel receives power from the main panel and has its own circuit breakers to control the flow of electricity to different parts of the building. This helps prevent overloading the main panel and allows for more efficient distribution of power throughout the building.
Is it safe to have 200 plus amps in breakers inside than 90 amps on the main service breaker outside?

It is typical for the breakers to add up to more than the main breaker under the assumption that you would rarely be running each circuit at its maximum capacity.
What is a sub panel?
A sub-panel is always fed from a main panel. The main panel is situated where the electrical service wiring first enters the main structure on a dwelling plot or building site.A sub-panel can be situated within the same building as the main panel or it can be in a subsidiary building or structure (such as a garage, garden shed or workshop) that is separate from the main building.More informationA sub-panel is another name for a secondary breaker box, just as "the main panel" is another name for "the main breaker-box"."Breaker-box" and/or "panel" are just alternative short names that are used instead of the full name "circuit breaker box".
Do you need a main dissconnect for a 400 amp 3 phase service?
Yes, a main disconnect is required for a 400 amp 3 phase service to disconnect power from the building. It is a safety feature that allows for easy shutdown of the electrical supply during maintenance or emergencies.
