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.
No, they will not work. Use only Murray breakers for safety.
First you need to determine if addition of the new breakers will exceed the 200A service under normal operating conditions. If so you will need to go to power company and increase service and put in a larger main panel. If you have the capacity for the extra current you can add a sub-panel and add the breakers there as well as the breakers you will remove from main panel to accommodate the sub-panel breaker. Another way depends on what breakers are in current panel. There are some breakers that can be duplexed in the same space as a single breaker.
The key to breaker compatibility is if it fits correctly into the buss bars in the electric panel.
Only a Square D designed breaker can be installed in a Square D manufactured panel.
Siemens bought Gould so a Siemens panel should work.
No, they will not work. Use only Murray breakers for safety.
To my knowledge Zinsco/Sylvania breakers are the only breakers that will fit in a Zinsco panel. My recommendation as a journeyman electrician is to have your panel changed out. Those panels are old and outdated, not to mention replacement breakers are expensive. Most newer panels, and breakers are the cost of about 2 replacements.

Breakers do not need routine maintenance. If the distribution panel is in an environment that allows dust or dirt to build up on the breaker faces, wipe the breakers with a dry cloth. If the distribution panel has a door on the panel face keep it closed.
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.
The number of tandem breakers allowed in a panel board varies depending on the manufacturer's specifications and the panel's design. Generally, most panel boards allow up to two tandem breakers per single-pole space, but it's essential to consult the panel board's labeling and specifications for the exact number allowed.
The provisioning of the breakers in a panel has a physical limitation regarding how many breakers will fit and a load calculation based on what devices the panel has to support. Your question really applies to both types of breakers. There are rules of thumb for sizing and populating the panel. This information is in the National Electric Code. If you have an existing panel and a new application requiring additional breakers for 220 Volt applications, the current draw in panel can be measured by an electrician and you will know what additional load you can support. If breakers fit physically in the panel, but connected devices exceed the total current capacity you will trip the main panel breaker. At this point you would need to get an electrician involved.
Cutler Hammer breakers are not interchangeable with American Switch breakers. It is important to use breakers specifically designed for the brand and model of your electrical panel to ensure proper fit and safety. Mixing different brands of breakers can pose a risk of malfunction or electrical hazards.

The legend identifying the breakers inside an electrical panel is typically just referred to as the "breaker directory" or "circuit directory." It is a list that indicates which circuit each breaker controls in the electrical panel.
Circuit breakers are typically located in a centralized electrical panel, which is commonly found in basements, utility rooms, or garages of homes and buildings. The panel is usually a metal box with a hinged door that can be opened to access the circuit breakers inside.
