Can a 8 amp be changed to 15 amps on circuit breaker?

If you are asking if you can change an 8 Amp Circuit Breaker to 15 Amps, the answer is no. If there is an 8 A breaker in place it is sized to protect the wiring and devices on the circuit. Increasing to 15 A would defeat this protection and could cause a fire or cause a connected device to be destroyed with higher amperage.


Can you install a tandem breaker?

Tandem breakers, often called split breakers or double breakers, provide two separate circuits in the space of a regular sized breaker opening. Every circuit breaker panel has a limited number of circuit openings available. The problem is that when the openings are all used up and you still need to add another circuit, what do you do? You could change the electrical panel or double up circuits on a breaker, but this could place too much load on a particular circuit. So what then? The answer that many have found is a tandem breaker. This type breaker is the same size as any other breaker, but it has its difference. This breaker sports two smaller breakers built into one regular sized breaker. Each has its own breaker switch and the breaker snaps in just like a regular breaker. With this simple innovation, you can add a circuit and protect the circuit on its own dedicated line.


What are the differences between a Miniature Circuit Breaker and normal Circuit Breaker?

An air circuit breaker, or air-blast circuit breaker, is a type of circuit breaker used in high-voltage transmission/distribution systems. It uses compressed air to (a) operate its tripping mechanism, and (b) to extinguish the arc created by a fault current. A miniature circuit breaker is a type of circuit breaker used in low-voltage applications, such as the protection of lighting and power circuits in a domestic residence. It uses a spring to operate its tripping mechanism, and relies on the speed of operation to extinguish the arc created by a fault current. Apart from the fact they are both designed to interrupt a fault current, there is really no other similarity.


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 do you change one breaker on a 3 wire that feeds two regular circuit breakers to a single arc fault circuit breaker - or do you have to change both breakers to arc fault so each has a neutral?

You can't change the one breaker, but you can't use two separate arc fault breakers unless you separate the neutrals. However double pole arc fault breakers are made for this purpose and the common neutral would be O.K.

What must you know before you change a circuit breaker?

Before you change a circuit breaker it has to be established that the breaker is at fault and not some other part of the circuit.


How do you change wire fuse for circuit breaker?

A circuit breaker does not have a wire fuse in it.


Can you upgrade a 15 Amps circuit breaker for a 40 Amp for a 8.5 Watt shower?

Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.


Is it possible that a circuit breaker can explode?

The definition of the word explosion is, a rapid expansion of gases. It may occur from physical or mechanical change. As there in no gases involved in a common circuit breaker the answer has to be a definite no. If a circuit breaker short circuits internally across the line the only thing that will happen is the safety protection up stream from the breaker will trip and take the faulted breaker off line.

What if your circuit breaker started tripping with no change of things plugged into an outlet Does this mean the circuit breaker needs to be replaced?

Circuit breakers can degrade over time but it would be better to get a competant electrician to do it. It might also mean you have too many things plugged into one outlet. Sometimes one circuit breaker may protect several outlets so it might be tripping because of a change in another outlet. ELECTRICTY IS DANGEROUS!!!! Don't do it yourself.

What causes circuit breaker to trip even when it's properly rated?

A circuit breaker is dual function. The only time it will trip is if it senses a fault current that is rated higher than the breaker rating (short circuit). The other trip condition is if the circuit is overloaded and is drawing a current higher than the breaker rating. On breakers that protect motor feeders the breaker has to be rated 250% higher than the motors full load amperage. If the breaker has lots of use and is used for a switch being manually turned off and on will weaken the trip value of the breaker. If you have access to, or know an electrician, a clamp on amp meter on the conductor that the breaker feeds will tell you what is happening. Clamp the line and turn on the load to see exactly what the current is. If, like you say, the breaker is properly rated and the current is within the breaker limits then change out the breaker for a new one.

Should 25 amps breaker be replaced by 20 amps?

For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
