In the USA, a National Electrical Code specifies things like circuit breaker sizes. The purpose of the circuit breaker is to protect the wiring (which is usually in a metal or plastic conduit, or in its own plastic insulation, and also is usually hidden in the wall, ceiling, or floor). The size of the circuit breaker (such as 15-amp, 20-amp, 30-amp) depends upon the size of the wiring.

Wire guage sizes (in USA) are typically 14 awg (for lighting and light-duty circuits up to 15 amps), 12 awg (bigger than 14 awg, for power outlets as well as lighting circuits up to 20 amps), and larger sizes for special purposes.

Most modern kitchens have two or more 12 awg circuits for the purpose of providing power to appliances such as toasters, mixers, etc. A 20-amp circuit breaker would protect a 12 awg wiring system designed to carry 120 Volts and 20 amps (amperes).

For safety, you must determine the size of the wiring in order to decide which size circuit breaker will protect it.

15-amp circuit breaker for 14 awg wiring (which is easy to bend with finger tips) 20-amp circuit breaker for 12 awg wiring (which is hard to bend with finger tips) 30-amp circuit breaker for 10 awg wiring (which is very hard to bend with finger tips)

The appliances and other items that you plug into an electrical outlet rely upon their own fuses or other design features for protection. The circuit breaker protects the wiring to prevent fire. This is IMPORTANT. Do not use a larger circuit breaker than the wiring can safely handle.

AWG = American Wire Guage Smaller numbers are for bigger wires. 6-awg is about as big as a wooden pencil. 30-awg is about as fine as a human hair.

I would add this: do yourself a favor, make 12 gauge wire your standard when putting in any new wiring (unless you are going higher than 20 amp circuit) . Don't mess with 14 gauge at all. The cost difference is peanuts.

A 15 amp dedicated circuit breaker should be used for the dishwasher. The disposal can be wired to the general kitchen 15 amp circuit.

Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker

You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.

Depends on how many amps it pulls and the size of the wire in the circuit.

The pool light is usually on a 15 amp circuit. The breaker feeding this circuit must have a GFCI rating.

The wire!! The breaker is there to protect the wiring not the device plugged into the circuit.

The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.

A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.

The sizing of the circuit breaker and hence the wire size to feed the pump are all dependant upon the amperage of the pump. This question can not be answered without that information.

$0 amp maybe but why not get the real specifications for your unit model from the mfg web site. The stove should have the nfo posted on iit somewhere also.

Most home consumer dryers use # 10 wire on a 30 amp breaker.

Read the literature for the ac condensing unit, or the tag on the outside of the unit. Minimum circuit ampacity= minimum breaker, wire and fuse size. Maximum circuit ampacity= the maximum size. Your circuit breaker, wire size and disconnect fuses should all be at or between those 2 numbers.

Depends on what size wire was used in that circuit. AWG #10 wire requires the use of a 30 amp breaker AWG #12 wire requires the use of a 20 amp breaker AWG #14 wire requires the use of a 15 amp breaker Check the wire size in the circuit and you will know what size breaker to use. It is not going to be a 25 amp breaker.

In North America the smallest size breaker in a distribution panel is a 15 amp breaker.

The size of circuit breaker you use for the plugs and geysers depends on the size of the house. Circuit breakers play an important role in homes in keeping electricity supplied.

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.

The circuit breaker protects the wire from getting too much current. Too much current could cause the wires to over heat and possibly start a fire. The size of the wire determines the number of amps that the wire can handle safely, so the number of amps on your circuit breaker should be based on the size of the wire.

Legally there is no law on this (under UK law) However, you will know if there are too many as this will cause the breaker to trip 'breaking' the circuit, and thus telling you there are too many =============== In the US, circuit conductor size and circuit breaker size are calculated before installation. If you are doing modification you should get the help of a professional in calculating what your installed wiring will safely allow.

For a 7000watts or 7kw a 240V then it is 30 Amp

Depends on the range but normally it will require a 60 amp breaker.

read the manufactures data plate on the back of the fridge it will tell you the amps and voltage of the fridge. But most likely will be a 20 amp circuit. code requires min size out lets for stand alone appliances in kitchen to be 20 amp.

To answer this question a voltage value must be given. Circuit breakers protect the conductors that feed the load. The lower the voltage value, the higher the current value, hence a larger the wire size is needed and therefore larger the breaker size for the circuit. In reverse the higher the voltage value, the lower the current value, hence a smaller the wire size can be used therefore smaller the breaker size for the circuit.

Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.
