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-energized

What else can I help you with?
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.
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.
Can you put in piggy back circuit breakers in a circuit panel?
The electrical terminology for this type of breaker is a tandem breaker. It is where two breakers circuits can be in the same one breaker slot in a distribution panel. On this type of breaker there will be two output for a circuit value of what ever the breaker is rated for.
What circuit breaker is used in a load center?
A common type of circuit breaker used in a load center is a miniature circuit breaker (MCB) or a molded case circuit breaker (MCCB). These circuit breakers protect the electrical system from overload and short circuits by interrupting the flow of current when necessary. They come in various sizes and ratings to suit different applications within the load center.
What are the common sizes of circuit breaker panel for all electrical home?
200 amp is the most common size used in most homes.

What is the maximum number of branch circuit breakers allowed in a 100 amp panel?
I just spoke with an inspector here in NJ today and according to him pending on what panel(squareD)in this case, it is 24 space but can be 48+. Stating that the breakers allow you to place two branch circuits on one breaker. Didn't make sense to me, being that while in school at my union it was 1 circuit for each breaker. Unless, some tandem breakers are used. Check the breaker and see what its rated for. Hope this helps.
How can one identify the type of breaker being used in a circuit?
To identify the type of breaker being used in a circuit, look for the markings on the breaker itself. Different types of breakers, such as AFCI, GFCI, or standard breakers, will have specific labels or symbols on them. Additionally, you can consult the circuit breaker panel's labeling or the manufacturer's documentation for more information.
What type of circuit breaker is required for a 240 v branch circuit?

Where circuit breaker are used?
Circuit breakers do not use anything, they are a controlling device. They can automatically open the circuit if the current exceeds the current rating and you can manually disconnect the power from the circuit.
Why tap in your house gives shock when it is touched or used?
Your water system is not grounded. Turn the main breaker in your distribution panel to off and ground the water system. If a "hot" wire has come into contact with the plumbing, when you turn the electrical panel main breaker back on a breaker will trip. This will give you the circuit that is at fault and a place to start looking for the short circuit.
