First, let me say that adding another breaker on any panel should not be done just because you can, and there is room. The power distribution panel is rated for a particular LOAD, or AMP maximum. This should be marked on the panel. Most residential panels are between 60A and 200A maximum. Overloading home panels is a very dangerous proposition as overheating, shorting or an electrical fire can occur. The first step in adding a breaker is to determine the full amp load of the panel at this time. There are tables that can help you to determine this but they do get a little complicated. They include finding Full Load Amp values for all of the equipment now on all of the circuits within the panel. Then you can start adding, de-ratting and averaging depending on the tables that you use. There are assumed load values for all outlets not used at this time, a total percentage of the conductor sizing that must be taken into account and various other steps. Your local electrical contractor can help you with the calcs or the whole process. Once you determine that another circuit can be added you can add a circuit that feeds a SUB-PANEL in which there is room for additional circuit breakers. In most full panels this will require removing two or more circuits and adding in its place a circuit to feed the sub-panel. If you do not want to get an electrician then at least get the help of a really good how to book on electrical how to. Your local home remodeling and repair supplier can usually help with this. As Always get the approval of your local jurisdiction or building official and get any required permits. On a scale of 1 to 5, I would rate this project at a 4 1/2 just because of the technical knowledge required to do the calcs. The actual work is relatively easy, about a 2 1/2 to 3 a good weekend project for an experienced home owner. Hope this helps ALWAYS REMEMBER… SAFETY FIRST! Terry

How many amps are on a double pole 30 amp circuit breaker?

The 30 A breaker you seem to be describing is a 240V breaker. There should be two black wires or perhaps a black and red wire connected to the two screws on the breaker. So the breaker would trip if more than 30A was demanded by the load with 240V across the load. What you have connected to the breaker should be sized such that the total current is no more than 80% of the 30 A.

What are the different kinds of electrical receptacle?

The most common types are the regular type, where the only over current protection is provided by the breaker panel. the other most common type is the GFCI (Ground Fault Circuit Interrupter) This type has a built in "circuit breaker" so when it senses a fault in the circuit it trips-this type is the safest as they are more sensitive than circuit breakers in the breaker panel.See related links below.

Can you put 2 20 amp circuits on one 20 amp breaker?

the answer is no period. You will only make this circuit breaker trip more often. you will need to install another 20 amp circuit or install what is called a piggy back circuit breaker. you can may find this at Lowes or Home Depot or better yet take a circuit breaker out of the electrical panel and go to a electrical distributor.

How do add an extra socket without breaking the circuit?

The key is to ensure that a 15amp breaker has no more than 6 220-240V wall sockets,if more than 6, the extra sockets must be serviced by a different breaker to avoid overloading the D.B

What is a circuit breaker and why are they helpful?

A circuit breaker ensures that a circuit cannot draw more amps that are rated for the breaker. It protects the circuit wires from overheating and arcing so that a fire or shock hazard does not result.

How much can a 15W circuit breaker handle?

Answer for the US: Breakers are rated in amps, not watts. However, a 15A breaker can handle 15 amps, or about 1800 watts (using 120V), or 3600 watts (using 240V). However, this is only rated for noncontinuous loads (those not lasting for more than three hours). For continuous loads (loads lasting three hours or more), one must derate the circuit breaker by 80%. So for continuous loads, that same breaker should only have 1440 watts (using 120V), or 2880 watts (using 240V) on it.

Can you use Auxiliary contact with circuit breaker?

You need to be more specific. Do you want a contact telling you if a circuit breaker is on? If that is your question, the answer depends on the model of the breaker.

How many amps are in a Circuit Breaker Double Pole 60A?

There is no current in a 60A circuit breaker. The above circuit breaker is a 2 pole circuit breaker that will trip when more than 60 AMPS is being drawn through either of the 2 poles.

What is similar between a fuse and a circuit breaker?

If they take more current then they are designed for then they break the circuit. (A fuse blows and a circuit breaker throws a switch).

If you are building a woodworking shop that will have several 240V tools can you install multiple 240V outlets on the same 30A circuit if only one or two tools will be running at the same time?

Yes you can have multiple 220 outlets, but if you are using multiple saws and start kicking your breaker, do not put a bigger breaker in to keep it from tripping you'll break up the protection inside of your wire, and then you'll have major problems. If it don't burn down. If you do start tripping the breaker you will need to run another circuit. Don't just "get used to resetting it." It is a very bad habit and will possibly wear your breaker out. -- HMM... not so sure about that. Maybe that's how they do it where nobody cares. It's against most electrical codes to put more than one 240V appliance on a single circuit, or even to create the possibility by adding receptacles. The simple answer would be to either add a circuit (within the limits of the panel and service) or to unplug one tool and plug the other in.

What is a difference between 10KA and 22KA circuit breakers?

The previous answer is incorrect, and I would advise that user to not give out information if they are going to give completely misguided information. The interrupting rating of a breaker is the maximum current that the breaker is designed to handle, at the breaker's rated voltage, before damage will occur to the breaker. A breaker will trip at FAR LESS than the interrupting rating, but it is extremely dangerous to expose the breaker to any situation where it will have more than the rated interruption current. the breaker is designed for. The reason some breakers are rated at 22kA instead of 10kA is because they typically have far larger conductors hooked up to them, so with the lowered impedance on the circuit there is more of a chance for the breaker to experience a higher fault current at the breaker. So electricians install 22kA breakers to handle the higher "available fault current."

Is a switch a circuit breaker?

No. A circuit breaker is a switch, but a switch is not necessarily a circuit breaker. A "circuit breaker" is a device that will open the circuit when more current than it is designed for flows through the circuit. This is an automatic function, and does not require manual manipulation (such as a person physically moving an on/off switch). Resetting is often a manual function. <<>> If taken in the context of a switch opening a circuit or making a break in the circuit then the question, Is a switch a circuit breaker, then the answer would be, yes, as the switch does break the circuit.

Why does an electrical breaker trip when you use a lot of appliances in the house?

A circuit's current is governed by the wattage of the load. The load governs what size wire is used to carry the current to the appliance. The breaker of the circuit is used to protect the wire of the circuit. When the load wattage becomes greater that what the circuit breaker is set to trip at, the breaker will trip. More appliances on the same circuit will increase the total wattage. The more wattage on the same circuit, the faster the breaker will trip.

What is a sub panel?

A sub-panel is always fed from a main panel. The main panel is situated where the electrical service wiring first enters the main structure on a dwelling plot or building site.A sub-panel can be situated within the same building as the main panel or it can be in a subsidiary building or structure (such as a garage, garden shed or workshop) that is separate from the main building.More informationA sub-panel is another name for a secondary breaker box, just as "the main panel" is another name for "the main breaker-box"."Breaker-box" and/or "panel" are just alternative short names that are used instead of the full name "circuit breaker box".

Why do you convert 120v circuits to 220v circuits?

You would need to change a circuits voltage if your adding a load that requires 220 when the present circuit supplies 120. If you need to do so it's pretty simple! First purchase a double pole breaker at the proper amp rating. Next find the breaker in the panel that supplies power to the circuit you wish to change to 220. Turn off the breaker and pull it out. Find the neutral for that circuit. Then double check and make sure it's the right neutral. Then check one more time. Now take the neutral and the hot wire for that circuit and connect them to the double pole breaker. install the breaker into the panel and turn it on. If you connected the right neutral you'll have 220 on that circuit. If you didn't you'll know because you'll trip the breaker.

How high a breaker box have to be off the floor?

The top of the breaker box cannot be more than 6 ft 7 in off the floor. No defining height is mandated from floor to panel box base. Defer to common sense when placing the panel box. Make it easy to see and read the top circuit breaker and location identifications of the remaining breakers.

What does a tripped circuit breaker indicate?

That something in the circuit has pulled more current than intended.

Why shouldn't you connect two wires to one terminal?

If you are referring to a circuit breaker in an electrical panel, each circuit breaker is designed to trip at a preset amperage rating. The NEC (national electrical code) only allows one circuit, rated at no more than 80% of the breaker rating to be fed from each circuit breaker. Generally the builder will design the electrical layout of any building to maximize and to most effectively balance the load for lighting and receptacles. Adding another circuit wire to the load side of the breaker already in use could have a potential for overload which could cause the breaker to heat up and trip, not to mention that it complicates things during troubleshooting. New circuits or other wire additions must have their own breaker.

Can you have more than one conductor in a circuit breaker?

No. Each conductor requires its own circuit breaker. Be sure to match the size of the breaker to the size of the wire. Ex.: 15 amp breaker for #14 gauge wire/ 20 amp breaker for #12 hauge wire.

How does a circuit breaker operate?

A circuit breaker can be magnetic; the higher the current is the stronger the magnetic field will be, if the magnetic field gets strong enough it will pull open the circuit. A circuit breaker can also be thermal; as current travels through the circuit heat is generated (higher current = more heat), in the breaker there is two different kinds of metal bonded together, each will expand and contract at different rates, since they are bonded together they will bend and trip the circuit open. A circuit breaker can be a combination of magnetic and thermal.

The Function Of A Twenty Amp Breaker?

It limits the current to the circuit at 20 Amps. If a load on the circuit draws more than 20 Amps the breaker will trip and interrupt the current to all devices on the circuit.

Can you use the vacuum circuit breaker instant of air circuit breaker?

no, arc quanching power is more in acb vcb use for 6.6kv but acb for 132 and above

Why does plugging too many appilances into the same circuit cause too much current to flow through the circuit what will happen as a result?

Each appliance has its own amperage. This can be shown by looking at the label of each appliance. A circuit is protected by a breaker which has a trip limit. By continually adding more amperage from different appliances, the circuit becomes overloaded. When the circuits limit is reached because of the additive effect of more appliances to the circuit the breaker will trip. This disconnects the appliance loads from the distribution panel supply and prevents over loading of the conductors of that circuit. Without removing some of the load amperage, the breaker will keep tripping when reset.

Is a circuit breaker a circuit?

No, it is an inherent part of the circuit.Further AnswerIn simple terms, a circuit breaker is a switchwhich is designed to break a fault current, which are many times greater than load currents. More specifically, a circuit breaker is a protective device designed to automatically interrupt overload currents due to overloads or short circuits.

Can you use 120 total amps on a 100 amp main breaker?

If you mean can he amps of each breaker in a panel add up to more than the rating of the panel then the answer is yes. In a panel design the electrician takes into account that each circuit will never be at its full capacity all the time. If each breaker was maxed out to just below its rated current and didn't trip, then the main breaker would trip if its rating was exceeded. This is highly unlikely with proper sizing of mains and individual breakers under normal circumstances.
