By duplex breaker, you mean 'tandem breaker', a special breaker designed to allow you to get more circuits into a panel that is full or almost full.
You most likely have a 'CTL' type panel in your home.
You MUST use 'CTL' breakers, or CTL tandem breakers in that panel. By design, if you look at the bus bars that your breakers snap onto, the upper 60 percent or so is different than the lower 40 percent.
The lower bus bars are designed differently so that you cannot install tandem breakers in a certain number of spaces. This prevents you from overloading the panel.
Most people at Lowe's and Home Depot do not know this and will give you anything to put into your panel. DON'T! If the CTL tandem doesn't fit, it's not supposed to. Do NOT go back to the store to get a different breaker because that one didn't fit.Call an electrician to install a larger service and panel with more capacity. Installing non-CTL breakers to cirvumvent the safety feature can cause your house to burn down.
It costs more to rebuild your home due to electrical fire, than it would have cost to have the job done right by a professional electrician.
The above answer is correct, but I would like to add there are some States that do not allow tandem breakers.
Yes, it is possible to overload a panel with too many duplex breakers if the total electrical load exceeds the panel's capacity. Each breaker is designed to handle a specific amount of electrical current, so exceeding that limit could cause overheating and potentially lead to a fire hazard. It is important to consult a qualified electrician to ensure the panel can safely accommodate the desired number of breakers.

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 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.
How many tandem breakers are allowed in a panel board?
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.
Are cutler hammer breakers interchangeable with American switch breakers?
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.
Name of the legend identifying the breakers inside an electrical panel?
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.
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.
What is the definition of electrcial panal?
An electrical panel is a metal box that traditionally contain fuses or circuit breakers to prevent overload of current.
What is ACDB panel?
ACDB stands for alternating current distribution board. A distribution board or panel is part of an electricity supply system. The panel splits the power up into circuits. At the same time, it uses fuses or circuit breakers to provide protection from electrical overload.

Will GE breakers fit a Murray panel?
No, they will not work. Use only Murray breakers for safety.
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.
What should you do if your 200A breaker panel is full and you need to add three forty amp two pole singal throw breakers?
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.
Should circuit breakers receive routine maintenance?
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.
