A two pole, (220-240 volt) circuit breaker can go anywhere in a panel where it will physically fit, connecting to two poles on the buss bar. However, if you don't know this already, you probably shouldn't be fooling around in a live electrical panel. You can get seriously hurt or burned.

What does a circuit breaker look like for 110 volt?

Most of the breakers in a panel will be 120 VAC. Double height breakers are 240 VAC. A triple height breaker probably indicates you have 3-phase power in 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.


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.


Can a 15 amp 240 volt circuit breaker be mounted in lower locations than the very top positions in the electrical panel?

Answer for USA, Canada and countries running a 60 Hz power supply service. On a electrical panel boards the wiring numbers go from left to right, top to bottom. There are 2 hot legs coming into the panel. L1 and L2. Breakers on L1 are 1,2,5,6,9,10. Breakers on L2 are 3,4,7,8,11,12. This is a 12 circuit board. This configuration allows every two adjacent breakers to connect to 240 volts. Example 1 and 3, 3 and 5, 5 and 7, 7 and 9, 9 and 11. Same with the even number side. So you see that a two pole breaker connects across the two hot legs L1 and L2 no matter where it is on the panel board. Any of these breakers on a panel board to the neutral will give you 120 volts no matter if the supply leg is L1 or L2. Just remember L1 to Neutral equals 120 volts, L2 to Neutral equals 120 volts, L1 to L2 equals 240 volts. So the answer to your question, it can go anywhere on the panel board where there are two spare slots.

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.

Will GE breakers fit a Murray panel?

No, they will not work. Use only Murray breakers for safety.


Will siemens breakers pass inspection on gould panel box?

As long as the breakers are made to fit the box, there shouldn't be a problem. you can only use breakers listed for the panel, there should be a label on the panel door. It will list all of the breakers approved for use in that panel. If you don't see the breaker by manufacturer name listed, then it should not be used. Lots of brands will interchange, but they have to be listed to be approved.

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.


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.


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.
