Some local electrical codes don't allow mini breakers, so check with local codes before you install them. As a general rule the total load of all breakers should not exceed the supply load of the main. As a general rule the total load of all breakers should not exceed the supply load of the main.
This is not a true statement . You will find that if you add up all the breakers, in most cases the total will exceed the main breaker total. On a 42 circuit board at 15 amp breakers the total will come to 630 amps. The way code looks at it is that not all circuits will be on at once and not all at full load. The main breaker only protects the service entrance wires. If the amperage of the main service wires becomes greater than that of the wire rating then the main breaker will trip.

The maximum number of circuit breakers in a breaker box depends on the size and capacity of the box. Standard residential breaker boxes typically accommodate between 20 to 40 circuit breakers. Specialty or commercial boxes can have more, up to 80 or even 100 breakers.

Can you add a 20 amp breaker to main breaker if total breaker amp is 320 amp Main breaker max is four 150 amp breaker?
No, you cannot add a 20 amp breaker to a main breaker if the total breaker amperage already exceeds the main breaker's capacity. In this case, your main breaker can only support up to four 150 amp breakers, which equals 600 amps, exceeding the 320 amp capacity. You would need to reconfigure the existing breakers to stay within the main breaker's capacity.
Can you use 6-3 NM wire and 50 amp breakers and 50 amp range cord for a 40 amp max load range?
No, it is not advisable to use a 50 amp breaker with a 40 amp-rated appliance like a range. You should match the breaker size to the appliance requirements. In this case, you should use a 40 amp breaker, 8-3 NM wire, and a 40 amp range cord for the 40 amp max load range.
What does a continuous load on a breaker mean?
A continuous load on a breaker refers to a consistent electrical draw at or near the maximum capacity of the circuit over an extended period of time. This differs from intermittent or fluctuating loads, which have varying power demands. It is important to properly size breakers for continuous loads to prevent overheating and potential fire hazards.
Can you use 10-3 with 30 amp breakers at 90 foot to run a 225 amp max arc welder?
No, using 10-3 wire with 30 amp breakers is not suitable for running a 225 amp arc welder. The wire size and breaker amperage should be appropriately matched to the current requirements of the welder to ensure safety and prevent overheating of the wire. In this case, a larger wire size and breaker amperage would be needed to support the 225 amp maximum draw of the welder.
What happens when you plug a 30 amp appliance into a 50 amp breaker?
If you plug a 30 amp appliance into a 50 amp breaker, the breaker will still function to protect the circuit from overheating due to excess current. However, the appliance may not draw enough current to trip the breaker in case of a fault, potentially causing damage to the appliance. It is generally recommended to match the amperage of the appliance to the appropriate breaker size.
Will turning off the main breaker turn off all the power to the circuit breaker box?
No. Power to all the circuit breakers will be cut off except for the Main power breaker. The Main power breaker (which supplies power to all other breakers and will say 100, or whatever your max breaker box power is, on it )will have power going to it all the time, unless power is turned off outside the house.
If you have two central air systems outside - a 25 amp heat pump and a 40 amp max electric for the main floor - why do the 80 amp dbl poll breakers on the main box throw when temps reach the 90s?
Check to ensure the connections are tight at the breaker box and the disconnect boxes. It could be that you simply have a loose connection. I have seen this occur from time to time and you may have answered your own question.When the temperature rises the breakers also heat up because of this,especially if the breaker panel is in the sun all day.If the breakers have some age on them try replacing them and checking the amp draw.
What is the max amps for a 4 gauge wire can 4 gauge feed a 100A breaker box?
Yes, # 4 AWG copper and 100 amps is the max.
Can you add a 20 amp breaker to main breaker if total breaker amp is 320 amp Main breaker max is four 150 amp breaker?
No, you cannot add a 20 amp breaker to a main breaker if the total breaker amperage already exceeds the main breaker's capacity. In this case, your main breaker can only support up to four 150 amp breakers, which equals 600 amps, exceeding the 320 amp capacity. You would need to reconfigure the existing breakers to stay within the main breaker's capacity.
How do you size circuit breakers?
If you are using 14AWG wire in your circuit, you will fuse with a 15 amp breaker as 14AWG maximum amperage is 15 amps to 100 ft of wire. If the wire run is longer than 100ft, then you would fuse for 10 amps max. If you are using 12AWG then it can carry 20 amps, etc. Longer than 100ft you would fuse for 15amps. note: 14AWG is called 14/2 and 12Awg is called 12/2 commonly.
Why making capacity is more than breaking capacity in circuit breakers and contactors?
Making capacity is the max fault current it can carry during closing of breaker, e.g. You are closing a breaker on fault. The making capacity is always higher because it is expressed in peak value not rms, and also because of the DC offset, voltage and PF while closing
Can you use 6-3 NM wire and 50 amp breakers and 50 amp range cord for a 40 amp max load range?
No, it is not advisable to use a 50 amp breaker with a 40 amp-rated appliance like a range. You should match the breaker size to the appliance requirements. In this case, you should use a 40 amp breaker, 8-3 NM wire, and a 40 amp range cord for the 40 amp max load range.
