There are many different sizes of panels so there is no direct answer to your question. Even the total amp rating of the panel doesn't make the determination. Every panel has only so many 1-inch slots, besides the main if there is one. So that number is your simplest answer. Also, some panels are rated for double breakers (not 2 pole, but doubles) which can double the number of circuits it can hold. Some panels are not rated for doubles and I don't know why.
It is important when choosing a panel that you not buy the cheapest one you can find because you will find it only holds 10 or fewer 1-inch breakers. Choose a panel with the total amp rating you need, then choose one that has more 1-inch slots than you expect to need. This may be much larger than you imagine.

Will GE breakers fit a Murray panel?
No, they will not work. Use only Murray breakers for safety.
How many 20 amp double pole breakers can go into a 100 amp panel?
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.
Will Homeline Circuit breakers fit in Siemens Electrical panel?
No, Homeline circuit breakers are designed for Square D electrical panels and are not compatible with Siemens electrical panels. It is important to use circuit breakers specifically designed for the brand and model of your electrical panel to ensure proper fit and function.
Will zinsco and gte circuit breakers interchange?
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 Those panels are old and outdated, not to mention replacement breakers are expensive.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.
Is it a Code violation to modify a breaker to make it fit in a panel?
Yes, modifying a breaker to fit in a panel is typically a code violation. Breakers are designed to specific dimensions and altering them can pose safety hazards, such as improper fit and overheating. It is recommended to always use breakers that are compatible with the panel and have been tested and approved by a recognized testing laboratory.
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.
What circuit breakers fit into an old Gould Panel GQF40MBB?
The Gould Panel GQF40MBB typically accommodates Gould or Siemens type circuit breakers. Common options include the GFCI, AFCI, and standard thermal magnetic breakers, specifically the GQ series. When replacing breakers, ensure they are compatible with the panel's specifications and ratings to maintain safety and functionality. Always consult the panel's documentation or a licensed electrician for precise recommendations.
How many air conditioners window units can fit on a single 20amp breaker?
Typically one.
Will other brands interchange with wadsworth breakers?
Wadsworth breakers are generally designed to fit specific Wadsworth panels and may not interchange with breakers from other brands. While some breakers from different manufacturers may fit physically, they might not meet the necessary electrical standards or safety requirements. It's crucial to use breakers that are specifically rated and approved for your panel to ensure proper function and safety. Always consult the panel's specifications or a qualified electrician for guidance.
Will a panel breaker for one manufacturer's panel fit on a different manufacturer's panel?
No, panel breakers are designed to fit specifically in the panel they are made for. Using a breaker from one manufacturer in a different panel could lead to compatibility issues, safety hazards, and potentially void warranties. It is always best to use breakers that are compatible with the specific panel being used.
Can ge breakers be used in a challenger panel?
Yes, GE breakers can be used in a Challenger panel as long as they are specifically listed to be compatible with Challenger panels. It is important to check the compatibility of breakers with the panel to ensure they fit properly and meet safety requirements.
Are cutler hammer breakers interchangeable with American switch breakers?
Your circuit box should have a label on the door listing compatable breakers. For instance, my American Switch 200 amp panel lists what American Switch breakers are usable on that particular panel, and then it goes on to list other manufacturers whose breakers will work in the panel. Mine can use Frank Adam Type A, FA-D, QP & QPH, Bryant Type BR-D and BD breakers as well as Westinghouse Type QP and Q. I am not sure that I would go with the adage that if it fits use it. Check your Panel Box for the tag listing compatible breakers.
