If you're referring to a plug like on the end of a cord for an electrical device, this would be Recepticle. Otherwise it is just UNPLUG
The third pin (not found on some electrical appliances) is for "Ground." This means that the appliance has a higher electrcal load and needs a ground wire to stabilize the output of electricity.
The modern standard Italian 230/240V grounded household plug is the Type F CEE 7/4 (German "Schuko" 16 A/250 V grounded) plug. This is a symmetrical plug with grounding clips on the sides and Live/neutral on the pins- as the plug is symmetrical, the location of L(black or brown) and N (blue) wires is "Don't Care" and can be either. The ground (yellow-green) is connected to the side plates. The E/F hybrid configuration is asymmetrical (polarized) the ground hole on the plug makes it impossible to insert the plug into an F type socket with a grounding pin in more than one way. Insertion into an E type socket is ambiguous so the N and L conductors may be interchanged in the E socket.
If you have a brand new appliance (hair dryer, toaster, fridge, tv etc) and it comes with a plug with three prongs it has a ground. If it comes with two prongs it is not grounded. The only time an electical appliance should not have three prongs is if it is "double insulated" double insulated means that the electrical components are on a chaisis that is electrically isolated from the outer case or chasis where the user can touch. This is done to greatly reduce the risk of electrical shock. If the device is not double insulated there must be a third prong or ground prong on the plug. The device will have a ground wire attached to the conducting parts of the device so that if there should be a failure such as a broken wire touching the parts that can be touched the electricity will have a path for electrical flow and again greatly reduce the risk of electrical shock to the user. If you plug in a three prong or grounded appliance and for some reason the breaker instantly trips there might be a dangerous electrical problem with the appliance which is causing electrical flow back through the ground conductor. this would also be slangly called a "shorted" circuit. It almost always causes the breaker or fuse to trip/blow.
no
Pull a plug out from the mains socket, open it up with a screwdriver, and have a look.
plug a block heater plug into any household 120 electrical outlet just like plugging in a heater in your house
Do not remove any electrical plug by grabbing the wire. This weakens the connection at the plug. ALWAYS grab the plug itself when removing it.
An electrical plug contains both conducting and insulating elements.
In China there are 2 types of plugs. There is the Grounded 3 Blade CPCS-CCC plug and the Non-Grounded plug. You will also find the British BS-1363 type plug in some parts of Hong Kong.
A fuse doesn't 'power' an electrical plug. A fuse protects the load supplied by that plug.

A current higher than what the plug is rated for will cause that type of condition.
The three pin plug is grounded (provided the receptacle is wired correctly).
never plug a RV in to a 220 it will burn everthing init up ,a/c, microwaves,TVs,convert box. alot of 50 amp plugs look like 220 but its not if you have a 30 amp unit u can run a cord from your house and plug up to it.

A plug with 3 pins which can be inserted into the original UK plug.
