What would you like to do?
Why would a circuit breaker that should be able to handle 2300 watts trip sometimes when you just turn on a 350-watt TV?
I would wonder if the items that are tripping the breaker are being plugged into the same outlet. There could be a problem with the outlet or the wiring in the box in the wall that the outlet is mounted in. If one of the screws on the back of the outlet that connects the wire to the outlet is loose, there would be a possibility of seeing your problem. Also, breakers can and do go bad. The more they pop, the more worn out they get. If you feel comfortable, you could try swapping the breaker in the box with another one of the same amp rating or just buy a new one since they aren't too expensive. You'll still have your old one as a spare or for an additional circuit to be added later. Answer The TV could also act as a large capacitor and draw alot of current right when its turned on and charging up(like lights dimming when you turn something like a tv on)

Depends upon the voltage, since P = I x E. If we were to assume 120 volts (typical in USA and a few other countries), and design load of 80 percent, you could safely supply 0.…8 x 15 x 120 or 1440 watts. Of course, the wiring would also need to support 15 Amps or more.
A breaker is a mechanical device and certainly would wear some with manual on and off usage, but it should be minimal and should not cause a problem unless it were defective. …There are many commercial applications where the breaker is used for daily on/off use for lighting and other functions. The breaker can fail by having a mechanical part malfunction or perhaps arcing between contacts that would corrode or fuse mechanical contacts.
The tripping mechanism for most high-voltage circuit breakers is released through the use of a solenoid built into the circuit breaker. The supply to the tripping solenoid is …from a DC source located in the substation building. There are various types of protection relay that will energise the tripping circuit -e.g. an overcurrent relay will detect a fault current due to, say, a short circuit in the protected line; after a specified time delay, a pair of contacts inside the relay will close, and energise the trip solenoid, opening the circuit breaker, and disconnecting the faulted line.
Breakers do not limit Watts they limit Amps. When I device is connected to that circuit and draws more than 15 amps the breaker will trip to prevent overheating of the conduct…ors and a possible fire. However if you do some basic simple math and multiply the 15 amps by the voltage applied to the circuit you could come up with a maximum wattage that will be present. Therefore assuming you are working with 120V: 15Amps x 120V = 1800 Watts of power. The electrical code states that circuit conductors can only be loaded to 80% of their capacity. So the maximum legal wattage load on a 15 amp breaker is 1800 x 80% = 1440 watts.
You need 12.5 Amps. For a continuous load you want to only have 80% of the current which would be 12 Amps. Best to go with a 20 Amp breaker.
Answer for USA, Canada and countries running a 60 Hz power supply service. Watts= voltage X amps At 120 volt total watts would be 2400 at 20 amps. The electrical co…de states that circuit conductors that are fed by this breaker on a continuous load can only be loaded to 80%. #12 wire rated at 20 amps, derated to 16 amps continuous = 16 x 120 = 1920 watts, #10 wire rated at 30 amps derated to 24 amps continuous = 24 x 120 = 2880 watts. On load calculations this derate should be taken into consideration. To maintain the required wattage needed for the load the wire size and/or the next size breaker may be needed.
A circuit breaker trips when the amount of electric current passing through it goes higher than its normal current rating. More detail The breaker trips to cut off the curre…nt flowing into in the circuit which the breaker is protecting. It is because of a fault - an electrical short in the wiring or in an appliance - that causes the circuit breaker to trip. If you - or an experienced person such as a licensed electrician - can find and fix the fault , then the breaker will not trip to cut off the current. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. 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.

50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.
To answer this question the voltage that is to be used should be stated. If the tank is 240 volts then 1500/240 = 6.25 amps. A 2 pole 15 amp breaker with a #14 wire will wor…k fine. If the working voltage is 120 volts then 1500/120 =12.5 amps. A single pole 20 amp breaker with a #12 conductor will work fine. The reason for the up size in wire for the 120 volt system is that conductors are only allowed to be loaded to 80% capacity. A #14 wire is rated at 15 amps x 80% = 12 amps which is just under the required amperage of the 1500 watt heater. A #12 wire is rated at 20 amps x 80% = 16 amps. The code book states that if the current of the load is over the capacity of the wire rating the next size conductor is to be used.
handling the circuit breaker
The operating handle will be found in mid throw. On smaller type electrical breakers there is a small trip indicator window and a red flag will be visible when the breaker has… tripped. On larger physical size breakers you will definitely see that the handle is not in the off or on position. To reset any size breaker move the handle to the full off position. You might hear a click but you will definitely feel the internal mechanism re-latch to the off position. This has reset the breaker, move the handle to the on position and normal electrical power will have been restored. If you get an instantaneous trip after a reset do not try and reset the breaker again. Find the cause of the short circuit and get it repaired. Constant and repetitive resetting will destroy the breaker and increase the temperature of the short circuit. If the short circuit is in a highly combustive area this is not good. Find the problem and get it repaired.
about 4800 watt but should not use it 100% so to be safe 4000 watt (80%)

A 120 volt, 600 watt light draws approximately 5 amps. In the US, electrical codes specify that continuous load current should not be more than 80% of the breaker rating, so a… 10A breaker would be the minimum size standard breaker. However, if this is a practical situation (as opposed to a basic arithmetic problem), it would be very unusual to put in a 10A circuit. Most residential lighting circuits are designed to carry 15A, even if that is not the immediate requirement. The occupant could decide to increase the load in the future.
You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping …under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.
Answer for USA, Canada and countries running a 60 Hertz supply service.Most likely it's a poor connection between the feed cable and either the meter base or the breaker panel…. You cannot legally work on a sealed meter base but if you have a "shutoff" at the meter base, turn off power to the breaker panel, verify that there is no power at the panel then tighten the connections inside the breaker panel. If that doesn't solve the problem, contact a qualified electrician. To amplify a bit, your breaker box is split into two parts each fed by one of two legs of a 230/240 VAC main supply. There will be three wires and a ground feeding the box. The white wire is neutral and Black is one side of the 230/240 VAC circuit and red is typically the other. Working on a main panel is very dangerous so calling an electrician is a great idea. If your house was fed with aluminum cable it tends to creep over time and the main screw connecting the wire to the bus bar tends to be loose. There is usually a compound use to stop oxidation when aluminum wire is used. You CANNOT just tighten this wire because it is LIVE. One of the possibilities is that some older panels may be fed from a fused disconnect box where there is a cartridge fuse on each of the two "hot" legs. The disconnect handle, when turned off, will remove power from each side of the fuses so they can be replaced.

A circuit breaker will trip if it is faulty or if the connected circuit has a short circuit or a connected device is trying to draw more current than the breaker rating. If yo…u disconnect the output wire from the breaker and it still trips, it is a faulty breaker. If the breaker is tripping immediately when it is turned on then start disconnecting elements of the circuit to see what might be causing the problem. If everything was working and now isn't, it is likely that the wire from the breaker is nicked where it exits the box and is shorting to the feedthru connector.
