New breakers can be purchased separately, and simply snapped into place in the modern breaker panels. Turn power off to panel before removing breaker panel plate. If you do not know what you're doing, save your life and hire an electrician to do it.

Can more wires be ran from the meter base to supply a shop from your house?
No, you cannot put but one set of wires in a meter base. The way to go about this, is to mount an outside panel beside your meter base. Panel sized to existing house service, equipped with two main breakers. One to re-feed the house panel the other to feed your shop.
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.
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.
How many 50 amp outlets can you run off a 125 amp main panel?
It depends on duty factor of each connected device. For a continuous load you can support 80% of 125 Amps which is 100 Amps. That would support two 50 A breakers each supporting a 40 Amp continuous load. If your loads were less and not continuous you can have more breakers. It is all a matter of supply and demand.
Is square d breakers compatible with ge breakers?
Breakers are build to snap onto a buss bar in a breaker panel. If they look the same on the back end then they will likely work. If not do not try to force a fit. To add a little more to this: 1st of all it depends on what kind of Square D you are talking about. Square D Homline breakers will fit in a GE panel but GE breakers will not fit into a Homeline panel in my experience. Square D QO is not compatible with either.
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.

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 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.

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.
Do you need a main dissconnect for a 400 amp 3 phase service?
No, you can use the six main rule. This means you would have a 400 amp main lug panel, with six breakers or less, but no more than six. You can also use six individual disconnects.
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".
