Answer for UK, Europe and countries running a 50 Hz supply service.
The easiest way to check is to remove the plug from the wall socket, and open it. The rating will be written on the fuse and is given in Amps. Sometimes devices come with a molded plug top (no screws, can't be opened), however there will be a slot on the underside of the plug which allows you to take the fuse out.
The Amp rating of a fuse in a plug is an electrical safety standard.
When a fuse burns out (blows) it is usually due to an electrical fault in the device, which should be fixed before replacing the fuse.
You should never replace a blown fuse with a fuse of a different Amp rating, either higher or lower.
In the UK and Ireland, plug tops should always come with a fuse with a rating that suits the appliance it is attached to.
Generally these ratings will be either
3 amps - for small things like lamps
5 amps - Also for small things.
10amps - no example
13amps for bigger things like the Vacuum cleaner.
13 amps is the highest rating a 3 pin plug should have.
As always, if in doubt, contact a registered electrician.

What us the rating of the fuse which is most Commondly fitted to three pin plugs?
If you are referring to the standard plug used in the UK, then the maximum rating fuse is 13 A, which can supply a load of approximately 3 kW. But the fuse fitted must match the power-rating of the load, so lower-rated fuses are available; for example, a 3-A fuse can supply up to about 700 W.
Why some plugs have three prongs?
Most modern plugs have three plugs, this is not because of a technical issue but rather a safety issue. The third prong is used as a way to ground the wire preventing electrical shock especially if you are working with a metal cased object. So to simplify things it is purely a safety pro-caution.

What is the maximum current rating of a standard plug?
In the US (and Canada and others??) the maximum current rating of a standard plug with parallel blades is 15 amperes. If it has the neutral (wide) blade rotated 90 degrees, the rating is 20 amperes. If it is has hot (narrow) blade rotated instead, the rating is 30 amperes. In Europe, using 230VAC configuration, there are several connectors. The main European connector uses two round pins for live and neutral and generally are rated at 16 amps although variations between countries also result in current ratings as low as 10 amps. In the UK, using three square pins, the maximum current is 13 amps. Unusually, UK plugs are fitted with a fuse which can be any of 3, 5, 10 or 13 amp rated.
What happens if you only replace the three front sparkplugs on a 2000 dodge grand caravan es?
Then you'll have three good spark plugs and three bad spark plugs. Not a good combination. I suppose you want to know if it will hurt anything though. The answer is no but if the three old plugs are shot it won't run very good.
