No, the plug and socket are incompatible, and even if you changed the plug, the unit would not operate on such alow voltage.
No, the amperage pin configurations are different between a 15 amp and a 30 amp plug.
yes
its ok..i found out that it can be done, as long as its not turned up to use more than 130amp.:)
Anything of such voltage will be burnt if plugged in a 230v socket outlet because the voltage is too high.
no
no,u can only plug in a PLUG to something
Depends upon which prong is horizontal. Under NEMA standards (in the USA) it could either be 250v (6-20p) with both non-grounded terminals hot, or 125v (5-20p) with the horizontal being neutral. Obviously, WHICH terminal is horizontal determines the possible voltage, so you cannot accidentally plug a 125v device into a 250V socket.
No, they are one and the same. I'm not an expert electrician but I do a lot of handy work around my house and local businesses. 110v, 115v, 120v and 125v are all the same. It has to do with voltage drops and increases due to supply and demand over varying distances from the power plant. Don't worry about the technical aspects of it all. In the same manner, 220v, 230v, 240v, and 250v are all the same also, just double of the original 110v. You probably shouldn't see 230v and 250v very much though. No biggie, whatever, all the 100's are the same and all the 200's are the same.
Yes provided the adaptor, or the plug that is plugged in, has a 13A fuse.
Yes because it is of a higher rating. But make sure your equipment can take the rating too.
Assuming that you mean a mains plug, then the voltage across the live and the neutral pins depends entirely on the the supply coming in to the socket. North America is rated at 110V while in Europe, the standard voltage is 230V. All supply comanies are allowed a tolerance of a few percent either higher or lower than the rated voltage. However, on a project I worked on in Eastern Europe some years ago, I monitored the voltage and although it was supposed to be 220V in that particular country, what I saw was between 156V and 250V. So, even if you know what the voltage, should be, you can never rally be sure!
