You'll need to know what the total current demand is for the circuit, then select the circuit breaker that will take the load without tripping, i.e. its rating will have to be equal to or larger than the demand. There are other factors to consider, but for domestic installations (in the UK) you'd normally install 'B' Type MCBs. If this answer hasn't clarified things, then you need to seek the services of a professional electrician.

What is the smallest size circuit breaker found in the normal home?
The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.
What can a loosely connected electrical wire in a breaker panel cause?
A short, which will trip the main breaker.
How do you read breaker box amps?
The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the breaker that is feeding it. In either case you must look for the manufacturer's label that will have the maximum current the panel can handle, make sure the breaker feeding the panel doesn't exceed this rating.
How do you ground a 100 amp service panel?
In the service distribution panel there are termination points at the top of the panel. Two of the utilities "hot" conductors terminate on the main breaker. The neutral utility termination point is on a terminal block usually off to the side near the main hot terminations. It is in this neutral termination block where the system ground connects from the ground rods to the distribution panel. For a 100 amp panel the wire size will be a #6 bare copper conductor.
How do you find out how big your main breaker box is?
Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.
What is the rating of the main circuit breaker of the 60kw power distribution panel?
200 amps
What is the purpose of a sub panel with a main breaker in an electrical system?
The purpose of a sub panel with a main breaker in an electrical system is to provide a secondary distribution point for electricity in a building, allowing for additional circuits to be added without overloading the main panel. The main breaker in the sub panel serves as a disconnect switch for the circuits connected to it, providing safety and control over the flow of electricity.
You lost a voltage leg by connecting the ground wire to the circuit breaker but com ed wires are still energized?
Yes this could be true. The breaker to the load will have tripped. The main breaker should still be allowing voltage to the distribution panel because it did not trip. If the main breaker tripped then the distribution panel must have been close to maximum amperage and the shorting of the branch circuit was enough to trip the mains.
When a voltage leg is lost by connecting the ground wire to the circuit breaker are com ed wires still energized?
Yes this could be true. The breaker to the load will have tripped. The main breaker should still be allowing voltage to the distribution panel because it did not trip. If the main breaker tripped then the distribution panel must have been close to maximum amperage and the shorting of the branch circuit was enough to trip the mains.
What is different between feeder breaker and motor breaker?
You have to be careful with terms in the electrical field, Example: Main Feeder Circuits will feed a Transformer for distribution and each of those main circuits might feed numbeous Motor control centers. However each of those circuits could be called a main feeder for the motor control center. Confusing. We have High Voltage Transmittion tansformered down for Distribution. So normally a Feeder Breaker will feed Main circuits that will be used for distribution. Example Your home panel will have a main feeder circuit to the whole panel and distribution breakers to you home.
What is the maximum amperage capacity of the main breaker in a 100 amp sub panel with main breaker?
The maximum amperage capacity of the main breaker in a 100 amp sub panel with a main breaker is 100 amps.
What is the recommended size for the main breaker in a residential electrical panel, specifically for a 125 amp main breaker?
The recommended size for a main breaker in a residential electrical panel with a 125 amp main breaker is typically 150 amps.
What is the process for replacing a 200 amp main breaker in a residential electrical panel?
To replace a 200 amp main breaker in a residential electrical panel, follow these steps: Turn off the main power supply to the panel. Remove the panel cover to access the breaker. Disconnect the wires connected to the existing breaker. Unscrew and remove the old breaker. Install the new 200 amp main breaker in the same position. Connect the wires to the new breaker. Secure the breaker in place and replace the panel cover. Turn the main power supply back on and test the new breaker.
What are the key differences between a main panel and a sub panel in an electrical system?
The main panel is the primary electrical distribution point in a home or building, receiving power from the utility company. It contains the main breaker and distributes power to various circuits throughout the building. A sub panel, on the other hand, is an additional panel that is connected to the main panel and serves as a secondary distribution point for specific areas or appliances. It is usually installed to accommodate extra circuits when the main panel is full or to reduce the distance of wiring runs.
How do I properly add a breaker to a panel?
To properly add a breaker to a panel, first turn off the main power switch. Remove the panel cover and identify a free slot for the new breaker. Connect the breaker to the panel's bus bar and then connect the circuit wire to the breaker. Secure the breaker in place and replace the panel cover. Finally, turn the main power switch back on.
What is the maximum amperage capacity of the main breaker in the electrical panel, specifically looking for a 100 amp main breaker?
The maximum amperage capacity of a 100 amp main breaker in an electrical panel is 100 amps.
What is the maximum amperage capacity of the main breaker in the electrical panel, specifically looking for a 150 amp main breaker?
The maximum amperage capacity of a 150 amp main breaker in an electrical panel is 150 amps.
