What would you like to do?
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.
Was this answer useful?
Thanks for the feedback!
The ampere rating of wire would depend on the diameter, length and usage of wire for specific purpose. Without additional input to the question. it will be hard to give an acc…urate answer.
constant: the same throughout the circuit
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, §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.
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.
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 four 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.
When you talk about a 220 volt wire and 110 volt wire, the reference is to the insulation factor of the wire. The amount of amperage that the wire has a capacity to carry is i…ndependent to the amount of voltage that can be imposed on the wire. When you see wire with ratings of 300 volts, 600 volts and 1000 volts, these are the highest allowable voltages that can be impressed without going over the manufacturers recommendation of allowable voltages. A wire that is rated for 300 volts indicates that the wire is rated for 120 volts or 240 volts or 277 volts. At test research facilities, equipment is tested to destruction. The maximum voltage rating, that is given to the wire as a result of these tests, is the highest safest voltages that can be applied to that particular type of insulation material. So if you hear an electrician say a wire is good for 110 or 220 volts, what is meant is that the same wire can be used for either 110 or 220 volts. To answer the question, you don't need to change a 220 volt wire to a 110 volt wire because it is good for both voltages.
Type your answer here... it all depends on what the condition is and how long you have had them. You shouldn't have to change them unless 1) You damage one or more changing pl…ugs 2) You get a code (check engine or MIL light sets it) that gives you a misfire count for a cylinder, I would them recommend a plug and wire change. Other than that, drive on and be happy!
by higher do you mean converting 1/2 to 2/4? if so multiply the top and bottom number by the same number
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
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 changing …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.
Resistivity of conductors increases with temperature, with semiconductors it is opposite, I believe always - but don't take that as truth! Look up the temp coefficient for wha…tever material you're dealing with - if it is positive, the resistance increases with temperature; if it is negative it decreases.
A: it does not
Up to 9.3 Amps.
Can a 20A circuit that trips often be changed to a 30A unit if the attaching wire is at least 10 gauge?
NO! The circuit is being overloaded. Danger of fire will result from just changing the size of the fuse or breaker. A 30 amp breaker may be used with #10 wiring…. #10 is rated for 30 amps. I would be hesitant to do this if the tripping problem is something new though.
A step down transformer can do it safely. However there is going to be some loss of efficiency with actual loading so a step down of 1:0.5 ratio can do it the power required i…s to be implemented.
Can 110V circuit with 2 wire size of 10 and a ground be converted to 220V after changing the outlet and breaker?
It depends on the amount of current (Amps) your breaker is rated for. If you boost your voltage the current will go down proportionally. 10 guage wire has an allowable ampacit…y of 30A. so if you are not drawing more than 27A you should be ok.
