Will a 100 amp breaker box work if there are 5 220 amp breakers and 7 110 breakers?
It will if the 100 amp distribution board is a 20 circuit board. Ten spaces for the 240 volt breakers and seven spaces for the 120 volt breakers. There are two types of 100 amp breaker boards, one rated at 100 percent and the other at 80 percent. Depending on what rating on the panel board you are using will govern the maximum amount of current that can be legally drawn from the board. This breaker board rating will also govern the size of the main breaker installed and the wire size to feed the board, either 100 amp wire or 80 amp wire. The second consideration is what are the connected loads to the breakers, with the total of seventeen breakers, the board can only supply as much amperage as the main breaker will allow.
Should a 20 amp circuit breaker get warm while in use?
Yes all breakers will get warm when in use. The full load current of the load flows through the device. Class A breakers current trip rating is rated at 40 degrees C. If in ambient temperatures higher that 40 C then the thermal trip rating lowers. Likewise if the ambient temperature becomes lower the trip rating increases. Sometimes breakers have to be rearranged in the electrical panel to keep high current breakers away from each other. The ambient temperature of adjacent breakers will raise a breakers temperature and cause needless tripping.
How big of a breaker for a 26 amp motor?
Sizing circuit breakers for motors falls into a different category. Because of the inrush of current when the motor is in the stopped position, the breaker has to be sized to allow for this. Breakers usually are 250% of the nameplate full load amp rating. The wires that feed the motor are sized to 125% of the full load amps of the motor.
How many 50 amp breakers feeding 50 amp outlets can you install from a 125 amp main panel?
Three or four would be normal. The total current should not exceed the rating of the main panel, so depending on how intensively the different circuits are used, more could be installed.
Can a 100 amp main have 2 50 amp breakers?
Yes.Additional InformationBreakers and fuses protect the wires to prevent fire. The 100 Amp breaker in the meter base (main) protects the wire from the meter base to the breaker panel. The 50 Amp breaker in the breaker panel protects the wire from the breaker panel to the outlet. Sometimes the 100 amp main breaker is located in the panel.If you are asking "Can you use two 50 amp breakers for the main breakers with a 100 amp service, then yes you can. The National Electrical Code allows you to use up to 6 breakers as the main overcurrent protection.
What does it mean when you have two 30 amp breakers linked together?
Two single-pole 30 amp breakers tied together make a two-pole 30 amp breaker. From this you can power a device that requires 220-240 volts, typically.
What do the difernt colour mean on blade or ceramic type fuses and circuit breakers?
Each color identifies the amp rating, yellow=20 amp, blue=15 amp and so on.

How do you get four twenty amp circuits from two twenty amp circuits?
Remove the two twenty amp breakers from the regular size slot and install two mini amp breakers. A mini amp breaker has two breakers per regular size slot.
How are quad circuit breakers used?
This would typically be seen in older residential installations where the service was of such a high amperage that the mains required larger breakers than were available (for that panel). Placing two breakers in parallel allowing sharing of the load. Two breakers per (split) phase would total four breakers. Two breakers of 50 amp rating each (in parallel) provide (generally) 100 amps of protection. Two sets of two would provide mains protection for a 200 amp service.

What sub should I get for a 1100 watt mono amp can I use two and wire them together how many watts should they be?
Depends on the rms or continuous rating of the amp and at what ohm is the amp stable

Three or four would be normal. The total current should not exceed the rating of the main panel, so depending on how intensively the different circuits are used, more could be installed.

Yes.Additional InformationBreakers and fuses protect the wires to prevent fire. The 100 Amp breaker in the meter base (main) protects the wire from the meter base to the breaker panel. The 50 Amp breaker in the breaker panel protects the wire from the breaker panel to the outlet.

The National Electrical Code allows you to use up to 6 breakers as the main overcurrent protection.
Can 100 amp distribution panel feed a 70 amp sub panel?
Yes they can. As long as the total load of all subs does not exceed the rated capacity of the main breakers, you should be fine, including 80 percent de-rating of any constant loads.
