What else can I help you with?
Is it safe to have 200 plus amps in breakers inside than 90 amps on the main service breaker outside?
I am assuming by your description that the panel is protected by a 90 amp breaker and the breakers in the panel when added up is 200. This is okay as long as your 90 amp breaker trips on a regular basis. It is typical for the breakers to add up to more than the main breaker under the assumption that you would rarely be running each circuit at its maximum capacity.
If an electrician have a circuit that pulls a load of 10 amps what size breaker must that circuit be protected by?
For a circuit with a load of 10 amps, a breaker of 15 amps should be used for adequate protection. It is important to choose a breaker size that is slightly higher than the load to prevent frequent tripping and ensure safety.
Is a circuit breaker better than a glass fuse?
Each device has its own special use. Glass fuses can protect circuit at very low amperages. They are usually used to protect printed circuit boards and control panel circuits. Breakers protect circuits from short circuits and overloads. These devices are used in service distribution panels to protect the wires that feed the loads. Circuit breakers can be from 15 amps up into the thousands of amps.
Can a sub panel from a 15 amp breaker be used with a branch circuit with 20 amp breaker?
Answer for USA, Canada and countries running a 60 Hz power supply service. Yes you can add these two breakers to the sub panel. You will have to keep in mind the fact that if the total loading of the two breakers exceeds 30 amps the 30 amp sub panel breaker will trip. If you use the 20 amp and the 15 amp loads individually then you will be under the 30 amp feeder sub panel breaker and good to go. With feeders of 3 conductor #8 the 30 amp breaker can be increased to 40 amp. If there are large motor loads involved this answer will change as starting current has to be calculated into the equation. View discussion page for additional information.SAFETY ADVICE Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What would happenif you put an 8 amp circuit-breaker in a power circuit?
If you put an 8 amp circuit-breaker in a power circuit that draws more than 8 amps, the circuit-breaker would trip or disconnect the circuit to prevent overheating and potential fire hazards. It is important to always use the correct amperage rating for circuit-breakers to ensure safe operation of electrical circuits.
How do you calculate the total amps in a breaker panel?
To calculate the total amps in a breaker panel, add up the amperage ratings of all the individual circuit breakers in the panel. This total amperage should not exceed the panel's maximum capacity, which is typically labeled on the panel itself.

What is the maximum current rating for the circuit breaker in this electrical panel, specifically in relation to the keyword "60 amps"?
The maximum current rating for the circuit breaker in this electrical panel is 60 amps.
What is the rating of the main circuit breaker of the 105kw power distribution panel?
To answer this question a voltage must be stated. Main breakers are rated in amps. This is the formula for amperage. I = W/E. Amps = Watts/Volts. As you can see a
What is the recommended amperage for a 30 amp RV circuit breaker panel?
The recommended amperage for a 30 amp RV circuit breaker panel is 30 amps.
What is the recommended range breaker size for a circuit breaker in a residential electrical panel?
The recommended range breaker size for a circuit breaker in a residential electrical panel is typically between 15 to 20 amps.
Why does the main circuit breaker trip but not the smaller branch circuit breakers?
If the main breaker has ground fault detection, and the fault is a ground fault, then only the main may trip. Also if the fault is a direct short, the fault current may be several thousand amps, much greater than the trip point of both breakers. Breakers have an I^2T curve (current squared-time), which is an indication of how fast the breaker will trip at a given overload. When both breakers are overloaded, the breaker with the faster I^2T rating at that current level will trip first. This would be an indication that the breakers are improperly specified or adjusted.
What is the rating of the main circuit breaker of the 60kw power distribution panel?
200 amps

For a circuit with a load of 10 amps, a breaker of 15 amps should be used for adequate protection. It is important to choose a breaker size that is slightly higher than the load to prevent frequent tripping and ensure safety.
What is making capacity of a circuit breaker?
Hard to define... A four year old child has the strength to physically "make" a typical household circuit breaker, while a teen would be able to "make" a typical industrial circuit breaker. (The latter breaker being physically much larger than the former.) Circuit breakers have their "breaking capacity" rated in AMPS. A typical household breaker is rated at 20, 30 or 50 Amps. Industrial breakers might be rated at 500 amps or a thousand or even more. Hope this helps but if it didn't answer your question, please rephrase it and ask again.
