Do you have to change the wiring as well as the circuit when changing to a higher amperage?
Definetely, in 23 yrs I have never had a case that would allow the wire/breaker to remain.

If you can change a 4-wire to a 3-wire 240V outlet circuit then what was the purpose of having a 4-wire box in place to begin with?
Answers ONLY for USA, Canada and countries using similar 60Hz mains supplies . You are not allowed to change a four-wire outlet to a three wire outlet. You can change a f…our wire cord to a three wire cord. That is VERY different!. . I have answered this question at least 6 times. The 4 wire plug has a neutral and the 3 does not. An untrained homeowner who does their own plumbing can flood the house with water or sewage, on the other hand electricity can kill instantly.. I wouldn't want to gamble my family's lives on my incompetence.. Blind leading the blind . 3 wire plugs are old and outdated. Way back in the old days they didn't ground equipment so plugs didn't have a ground. (Remember the old 2 wire 110V outlets on houses built before the 50s?) A few people got killed so they decided to add a safety wire. It took them longer to catch on with heavy appliances, but eventually they did. That it what the fourth pin is. Since many homes still have the 3 wire plug it is allowed in older homes. New homes must use the new 4 wire plug.. Changing your 4 wire cord to a 3 wire cord is the same as plugging a 3 wire 120V appliance into one of those 3 prong to two prong adapters they sell. Your appliance works now, but is ungrounded.. Don't listen to anyone who says to replace the new up-to-code plug with an older plug. That is the same as replacing your 3 prong 120V outlets with old two prong outlets! Ignore anyone who tells you to do so, they think they know a lot more than they actually do. Buy a new cord. It is cheap and safer.. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use an electrician's test meter having metal-tipped probes (not a simple proximity voltage indicator) to insure the circuit is, in fact, de-energized. .
Can a 15 amp circuit breaker be changed to a 20 amp without changing the wiring and what gauge wire is correct for 20 amps?
in most circumstances #12 AWG wire is suitable for 20 amps. Changing a 15 amp breaker to a 20 amp breaker even if the wiring is #12 can create a violation and or a danger dep…ending on the circumstances of the circuit and loads involved.. This topic is discussed at length in the National Electrical Code
Can a 10 amp circuit breaker be changed to a 15 amp without changing the wiring and what gauge wire is correct for 15 amps?
14 gauge wire is rated for 15 amps wich is the smallest size breaker that is used in the US. I never heard of or saw a 10 amp breaker and I am a licesened electrical contracto…r. The 2008NEC (NFPA70) lists 16AWG copper allowed for up to a 10 amp CB, and 18AWG copper for up tpo a 7 amp CB, max current. Continuous loads must be derated to 8 amps and 5.6 amps respectively, see NFPA 70 2008, Â§240.4 (D) (1), (2)., but these are only going to be found in industrial applications. Would the asked be so kind as to tell us what kind of equipment the 1 amp breaker is on? 14 AWG is still the minimum for a 15amp CB in general, this change might not be wise without an electrician looking at the entire circuit.
I=V/R The smaller the resistance the greater the amperage.
A circuit breaker does not have a wire fuse in it.
because they are safer and people got confused with the colours
The fuse is supposed to be the weakest link in the circuit. The circuit is rated to handle a specific load current. The wire and insulation rating of the circuit is governed b…y this specific load. If this load malfunctions and the load current becomes higher that what is specified, the fuse is there to break the circuit. A fuse of a higher rating than what is called for will allow a higher current to flow through the circuit which could cause the insulation on the wire to melt, the wire to burn open or components in the circuit to become unusable. Never over fuse an electrical circuit with a larger amp rated fuse.
True or false if the voltage and resistance of a circuit stay constant the amperage can never change?
The equation for the three values in the question will give the definite answer. Amperage (I) is equal to the voltage (E) divided by the resistance (R). I= E / R So as you c…an see the answer is True. Example: 10 Volts and 50 Ohms in a circuit will have a current of .2 Amperes flowing through it. 10 / 50 = .2 You can also rearrange the equation to find the other two: E= R * E R= E / I
You cannot increase amperage without changing voltage or resistance. Ohm's law states that voltage is current times resistance. You cannot change one alone. Not even changin…g frequency in a capacitive or inductive circuit will do this, because changing frequency represents a change in reactance, which is effectively a change in resistance.
Dryer plug three to four Open up the electrical access panel on the back of the dryer. You will see a terminal block with three wires going into it from the plug cord assemb…ly. A red and black and white are now connected to the terminal strip. Look at the position and colours of the existing 3 prong cord and how it is connected. Make a diagram. Coloured wires on the outside terminals white in the center. From the center wire terminal you will see a jumper strap that goes to the frame of the dryer. When installing the four prong plug this jumper is removed completely. The kit should have with it a grounding lug that connects to where the removed grounding strip attached to the frame of the dryer. This is the attachment point for the fourth green ground wire from the new dryer cord assembly. Make certain that it's wired properly; White=Neutral Green or Bare Copper=Ground Black, Red = Hot there should be 2 "Hot" wires in a 4 wire 240 V circuit, one Neutral and one Ground. Make certain that you study the outlet to determine where the wires go. If the breaker keeps tripping, something is wired wrong. If you cannot easily find the problem, contact a local electrician or handyman for help. (assuming that your state allows a handyman to perform minor electrical repair) Make sure you also remove the jumper between the ground and the neutral on the dryer.

Sure; the fan has 3 wires so you can wire the light and fan separately, but if you don't have that option, you don't NEED to put the fan and the light on separate switches. …You can always turn the light or fan on/off using the pull strings.
Spark Plug Wires? Remove them 1 at a time from the spark plug to the distributor or the ION pack, remove and replace the spark plug, add the new spark plug wire from the newly… added spark plug to the distributor or ION pack.
Then you have to call a girl over to help you because girls can handle these things.
A #8 copper conductor with a 90 degree C insulation factor is rated at 40 amps..
What are the signs of chemical change in connecting the wire to the dry cell to form a closed circuit?
The wire and the dry cell are combined into one, therefore it formsa new subtance.
The most sensible solution is to get a qualified electrician to check the wiring to see what the maximum load should be, and if necessary re-wire with higher capacity wire/con…figuration. . You can (there is nothing physically to stop you), but whether it is a good idea or not is a totally different matter - you risk starting a fire if you do. The breaker amperage is set based on the wiring of the circuit - the wire used, along with how the wiring has been done, will limit the maximum current that can be allowed through the circuit; if this maximum is exceeded there is a risk of the wiring overheating and causing a fire.
