The voltage rating of the cord is actually an insulation rating of the wire in the cord set. Your cord has a maximum voltage rating of 300 volts or less. The other standard maximum voltage cord ratings are 600 volts and 1000 volts. 480 volts would drop into the category of 600 volts or less.

∙ 12y agoEach voltage has a range and devices rated in that range will all work . The 110 to 120 volts is one range of voltages. The 220 to 240 is another range of voltages. The reason there is a range of voltages is to help the utility company out. They are mandated to keep the voltages within a + or - 5% range of a set voltage. Because there are loads coming on line and loads dropping off line the voltage fluctuates. Using a base voltage of 115 and 230 volts means that the voltage can rise by 115 +5% = 121 volts and drop by 115 - 5% = 109 volts. In the 230 volt range the voltage can rise by 230 + 5% = 241 and drop by 230 - 5% = 219 volts. As you see they are still in the usable voltage ranges.

∙ 12y agoWhat comes into play here is the insulation rating of the extension cord. Most cords are rated for 300 volts even though they are only used on 120 volts. As long as the correct 240 volt cord ends are applied to the extension cord it can be used on 240 volts and still be within the limits of the 300 volt insulation factor of the cord.
That said as for using a 120 volt appliance on a 220 volt receptacle, do not try it. The 220 volts applied to the 120 volt manufacturer's designed appliance will destroy it. The manufacturer states the proper voltage that is to be used on their equipment and it is meant to be adhered to.

∙ 10y agoYes, what comes into play here is the insulation rating of the extension cord. Most cords are rated for 300 volts even though they are only used on 120 volts. The ratings applied to extension cords is the highest voltage that can be safely applied to the cord. Construction cords are usually of a higher voltage rating. Not because of the 120 volts they are used for but for the outer jacket can take more abuse that is found on construction sites.

Can you plug a 250V appliance in a 220V outlet?
Shouldn't be a problem. The 250V is likely a maximum rating and it is designed for 220-240 V service. Just make sure the current draw is less than the circuit breaker rating.Another AnswerIf you are referring to a European residential service, then you should be aware that the nominal voltage is 230 V, not 220 V, and there are no such things as 250-V appliances. An appliance's rated voltage will always match the nominal voltage of the supply they are designed to operate from.But you should be aware that 230 V is a 'nominal', or 'named', value -the actual value is allowed to increase by 10% -in other words, it can be up to 23 V higher than its nominal value. This means that you can expect a 230-V supply to vary up to 253 V.
Can you use 300v cable for 240v?
You most certianly can. Voltage ratings on wires are 300V,600V and 1000V. These are the maximum voltages. 120 - 240 on 300V, 480 - 575 on 600V, 1000V wire is a special order used for specialized equipment.
Can you use 10ga wire for 220 volts?
There is a big misconception that there are two types of wire for different voltages. It is the insulation factor that governs amount of voltage that can be applied to a conductor. Most conductors have three standard voltage insulations, 300V,600V and 1000V. These are the maximum amount of voltages applied to each insulation. The type of insulation and size of a conductor governs the amount of amperage that can be legally applied to the conductor. To answer your question "yes" you can use 120V and 240V on 300V insulation. The "gauge" of the wire is the wire size measured in AWG. )American Wire Gauge. The code book lays out the amount of amps that are allowed on each size.
What is the output voltage of an insulation tester which is required to test a 230v circuit?
On a hand crank megger which is used to test insulation breakdown, use the 300V setting. If the megger does not have that setting use 500V as opposed to 1000V for the test. The output of the megger is a DC voltage.
Can i get 9V to 110V transformer in the market?
Sure. You can go a couple of ways. You can look for a 110v to 9v transformer, if you can find one, or you can get a 110v to 18v center tapped transformer. If you get the second one, when you hook up the 9v side, you connect between one of the ends of the 18v coil and the center tap. Right now you're thinking, "I said a 9v to 110v transformer, not a 110v to 9v." That you did, but transformers don't care about that--they'll step voltage up as readily as they'll step it down. (Back when all we had was tubes to work with, transformers with a 6v winding and a high-voltage winding--300v, 400v, 2500v, whatever--were very common because tubes need a LOT of voltage to work.) There are two things you really should think about here if you're trying to take 9v to 110v. First, if your intention was to get line voltage out of a 9-volt battery, stop right here. Transformers only work with AC voltage, and a battery puts out DC. The other thing is, if you've got 9v AC and you feed it into a transformer that will give 1A at 9V, 0.08A at 110V will come out of the unit. Eight one-hundredths of an amp isn't really enough to do anything with. If you want to get 1A worth of 110v from 9v, you need to feed (assuming perfect efficiency in the transformer, which you will not get) 12.5A at 9v, or 25A at 9v if you have a transformer with a more likely 50 percent efficiency. It's possible to step 9v up to 110v, but it's probably not worth your time to do so.
What happens if you power a 120v light bulb with 300v?
Of course this is a bad idea. It will likely look like a flash bulb and may explode the glass. Do not do anything like this.

Why insulation resistance test is required?
every insulator has its own voltage range depending on its intended use. we test insulation for the required operating voltage range. usa uses a document known as nfpa 7 or nec most common residential wiring 120v to ground is in the 300V class the specified test voltage for 300V wire and wiring devices is 2 times the working voltage +1000v which is 120v x 2 + 1000v = 1240V spec 1600V for industrial wiring its 600V class wire and wiring devices 480V x 2 +1000v = 1960V spec 2200V for most uses a 2500 volt megger is sufficient
Why is there 300 volts ac between the neutral and the earth in a house?
for USA, Canada and other countries running a 60 Hz supply service.In a typical house wired for 120V and 240V, the neutral and earth should be bonded at the main panel, upstream of the circuit breakers, so there should be no difference (though you may notice a small difference as you get further away - such as in an attic). Perhaps you're measuring peak instead of RMS, and you're measuring hot to hot on two different legs of 120V? This would give you 240V RMS, or ~300V peak.So, if you're measuring ~300V peak to peak, maybe what you think is a neutral wire is actually another hot wire from the other 120V leg - or you could be measuring between the two hots on a 240V circuit.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Can 14 gauge wire carry 220 volt?
Wire guage is used as a measurement for the ampacity of the wire. # 14 wire is allowed 15 amp to be applied to it. Voltage is governed by the insulation factor of the wire. The three standard insulations are for 300V, 600V and 1000 volts.
