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.

Can double pole circuit breakers be changed into single to create more room in the pannel box?
Yes. The double pole breaker can be removed and replaced with two single pole breakers. The double pole breakers are only used for 240 volt supply loads.
Where do you use double pole circuit breakers?
For 220v circuits
Can a 220 VAC breaker be single pole or does it have to always be a double pole breaker?
U.S. 240 VAC breakers are always double pole since they are protecting two legs of the circuit.
What breaker boxes are compatible with GE circuit breakers?
GE circuit breakers with catalog numbers ranging from THQL1115 through to THQL1150 can be substituted like for like with Cutler-Hammer circuit breakers coded CL115 through to CL150, ITE Siemens circuit breakers coded Q115 through to Q150 and Square D circuit breakers coded HOM115 through to HOM150. These are single pole breakers. GE circuit breakers with catalog codes from THQL2115 through to THQL2150 can be substituted with Cutler-Hammer circuit breakers CL215 through to CL250, Square D circuit breakers HOM215 through to HOM250 and ITE Siemens circuit breakers Q215 through to Q250 of the same amperage and voltage. These are double pole breakers.
Why does my heating and air conditioner in my house have 3 double pole breakers - a 30 40 and 50?
In North America a two pole breaker usually represents a load that requires a 240 volt source. Larger current load appliances use 240 volts to reduce the feeder size and there by reduces the cost factor when wiring a building. Two pole 15 amp breakers are used for kitchen counter split receptacles.Two pole 20 amp breakers can be used for baseboard heating and hot water tanks.Two pole 30 amp breakers can be used for clothes dryers and some heating units.Two pole 40 amp breakers can be used for electric ranges.Two pole 50 amp breakers are not common in home wiring circuits. It might be used for an electric furnace or some other high current device.

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.
How many 20amp breakers will fit in a sub panel?
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.
3 pole circuit breakers?
3 pole circuit breakers are used for 3 phase lines
Why would a dryer in Canada run off of 2 single pole 15 A breakers without tripping and dry clothes perfectly?
My mistake. They are single pole 30 amp breakers. Probably should replace with a double pole. Sorry for any incovenience to this forum. d

What kind of breakers are used in Heating and AC?
Can be 30, 40, or 50 Amp 240 volt double pole depending on the HVAC specs.
Do they make a 30-40 amp two pole breaker compatible with a square d breaker?
No, if you have a Square D distribution panel only Square D breakers will fit in it.
Where is the silver in curcuit breakers?
It is on the contact pole faces.
