I have a extension cord that is labelled 125V and max watts 1250. can i use the same extension cord in a 220V outlet or will it short circuit? thanks...
Answer:
If you%26#39;re in America and the building you%26#39;re in has been wired correctly, I don%26#39;t think the 110 cord will fit in a 220 outlet. It%26#39;ll be ok for a power drill or a hedge trimmer but I wouldn%26#39;t rely on it for any heavier load. A reduced low voltage system, which delivers 110V to the equipment is safer than using 230V.It effectively eliminates the risk of death and greatly reduces the degree of injury in the event of an electrical fault.
The insulation on the cable is not designed to work at the same temperature as the 240 volt system, so if it gets hot, it may fail as it is being asked to work outside the parameters of the amps it was designed to run at. Hence the orange colour, and blue for 240 now days, so you do not recycle the cable for another extension lead. You lead will have a current carrying capacity for the cable, A 1.5 mm 230 volt /14amp cable will need to withstand the heat generated by 10 ohm resistance, but are designed to take twice this. The equilavalent 110-volt only needs to withstand 5 ohms so can be constructed with thinner insulation. Some suppliers will used thicker insulation, most however, will use the cheapest cable they can, so Why take the risk? its not the voltage but the amps u draw a 110 cable normaly use higher amps than 220 240 volts It will probably catch fire, don`t even dream of plugging it in.
