Assuming inside the lighting/distribution panel, the Neutral bar is "bonded" to the ground bar. Then the neutral prong (usually larger) of the receptical is then directly wired to the Neutral bar in the panel. The above technique keeps the NEUTRAL at GROUND potential, however, the metalic frame of the appliance remains UN-GROUNDED if the supply cord is only 2-wire. The NEUTRAL connection inside the appliance is not allowed to be bonded to the frame of the appliance. Therefore, the un-grounded metal frame of the appliance can become a shock hazard if there is a fault in the appliance's internal wiring

Why is it not safe to plug an appliance with a three-prong plug into an extension cord with a two-slot socket?
Because - the 2-prong socket is NOT connected to earth !.. Any fault in the appliance - could result in electrocution.
How do you connect a grounded lamp to a ungrounded outlet?
Change the outlet to a grounded one. Get an adapter that goes from 3 prong to 2. Break the ground prong off. Any one of these will work.
This is a 2 prong polarized female. However a 2 prong unpolarized male will easily plug into a 2 prong polarized female. just not the other way around.?

Can you plug a 2 prong extension cord into a 3 prong extension cord?
I don't know about an extension cord, but they do sell plug adabters. You can pick them up at any hardware store or even Wal-Mart. They are ussaully grey or orange , and look like the plug end of the extension cord. One end will have the 2 prong, the other side will have the slots to plug in the three prong.
What do you do if you have no outlet for your dryer's 2-inch 3-prong plug?
call an electrician!!!
What is the difference between a 4 prong dryer outlet and a 4 prong stove outlet?
The four blade dryer plug brings a separate ground wire from the machine to the electrical grounding system. The three blade dryer plug depended on the neutral wire of the plug to make this connection.
How do you earth a plug with 2 wires my heater says it must be earthed but came with a fitted plug and not earthed it has blown the plug twice any suggestions?
The heater has a three prong plug and the outlet has 2? If it has blown the fuse or circuit breaker, it is drawing more current than the circuit can handle. That is the purpose of the fuse. If you only have 2 prong outlets, it is probably mounted in a metal box that should be grounded. It may not be or it may be in a metal box but the box is not grounded. They make an adapter that has a tab you put behind the screw that is holding the outlet cover in place. Grounding the heater is not going to stop it from blowing the circuit. Try a different outlet, remove something that is on the same circuit or use a heavier fuse which is not always a good idea.
Can you still use single pole electrical sockets?
if you mean 2 prong sockets instead of the 3 prong ones no. they were illegal in usa in kitchens since 1960 have you ever seen a toaster with a grounded plug? they are illegal everywhere in the usa since 1981 now they are illegal to replace a broken 2 prong with a new 2 prong you SHALL run a ground wire and replace it with a grounded receptacle you can buy them in most stores. if you use it it will fail inspection and invalidate your fire insurance. you can also buy #18 100' extension cords that arent grounded. if you try to use a power saw with it chances are it wont cut thru a 2" board. light bulbs still use a single pole threaded Edison socket so yes you can with light bulbs. there are still Edison receptacles in some old houses. they were replaced with the prong ones without grumbles because its harder to stick your fingers in em and most people don't like the tingle.
Can you change a 2 prong plug with a three prong plug if you use a GFCI breaker?
NO - it is not safe to do that. A GFCI breaker is only a secondary safety device and your primary safety still depends on the earth wire in a 3-pin supply.
Is it legal to have a 2 prong socket in your house?
Generally yes, but it depends on the building codes in your area. Homes that have not been updated may have the older two prong sockets. All newer homes will have the three prong or grounded sockets. Any new construction would require three pronged sockets.
Is a 2 pin plug safe to use?
This depends on what device you use, and where you are using it. If you have a grounded outlet, it is always advisable to use a grounded (3 prong) device over a non-grounded (two-prong) device. Grounding a device has several main benefits. In high current devices, grounding prevents accidental electrocution and dangerous surges. In low current or highly sensitive devices, it protects from current spikes, prevents problems due to static electricity, and decreases electromagnetic noise. In most devices that aren't high-current (like a toaster), or high-sensitivity (like a computer); there is not much of a benefit.
What electric plugs are used in china?
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.
