Is it safe to plug in three prong appliances into a three prong wall outlet that has no ground to it?

The NEC allows connection of ungrounded, 3-prong outlets if there is a properly installed GFCI "upstream" of the ungrounded outlet.
As long as everything is working as designed, nothing will happen, but that third connector is a safety feature to protect you. It is connected to the frame of the appliance and if there is an internal short, leads the electricity back to ground. Without that connection, the operator may become the ground, i.e., crispy critter.
No, it is not safe. Ground is a safety line, without it the appliance is not safe. It may work, and you probably will not be harmed, but it is not safe.

∙ 14y agoNever do this. The third pin is there for your protection. It is the ground return in case of a short circuit. It is this pin that protects you from an electric shock in a fault condition. Up grade your extension cord. If it is a three wire cord install a new plug cap and receptacle cap. If it is only a two wire extension cord throw it away. Your safety is more important that modifying equipment that has been designed to keep you safe.
nope sorry... :(

Black to brass colored screw or the screw marked "hot".
White to silver screw or the screw marked "neutral".
Ground to green screw or the screw marked "ground".

∙ 12y agoYes, you can, but watch out for short circuits, as the two prong plug doesn't have an earthing pin.
Edit: The neutral acts as a ground in North American 120v. Without the ground the double fault is lost. Wiki NEMA if you are north American for more information.

∙ 10y agoIt's always dangerous to have a 3 prong outlet that isn't grounded unless it's a GFCI outlet or electrically down stream from a GFCI outlet. Down stream means the outlet is further away from the circuit breaker -- not physically further away, but further from the breaker electrically

Can you plug a 3 prong extension into a 110 volt outlet?
Yes, provided the outlet has a three element receptacle. The third prong is ground. If you use an adapter that connects three prongs to a two slot outlet there is a shock danger.
Where do you ground the extra wire when plugging a 4 prong wire into a three prong outlet for a dryer at?
It may be a 220 Dryer, and you will need a new outlet installed. There should be no extra wires when connecting the Power cord to the plug
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 adapt a 3 prong German plug to fit into a 3 prong US 230 dryer outlet?
German appliances don't have three pinned plugs. The standards are the "Schoko" plug, which is a two pin plug with contacts on the side as a ground connection and the "Euro plug which is a two pin plug without a ground connection. There are adapters available at most good electrical stores.
What if the top pin on three pin plug broken in electric socket. Is it dangerous?
Not in itself. Do not plug another three prong plug in the outlet until the broken prong (round-ish) is removed from the outlet. The third prong (round-ish) on a three prong plug is the ground. It does not carry any power.Correction"It's the power return"
Can one convert a two prong outlet to a three prong outlet?
Yes, provided that you have a ground wire in the box and that the ground wire is properly connected in the electric panel.

There is not enough information stated as to what you are trying to do.

Which prong on the back of a three prong headlight sealed beam is ground?
Is it a plastic prong sealed together
What does the third prong ion a three prong pulg do?
The 3rd round plug is the ground connection.
What is the function of the 'ground' prong?
Basically, Your ground prong is essential to protecting you from being in contact with an "unsuspecting Live current flow." It eliminates YOU as the primary grounding to whatever your plug is supplying power to, and sends any current flow, manually drawn (like touching it), into the ground prong. Your feet touching the earth acts as a "grounding" process, but with a ground prong; itself alone acts as the ground for you, allowing you to escape the ability to receive external power.
What type of appliances have three prongs?
The third prong is to protect from shock. If there is any way for you to come in contact with a conducting surface on the appliance you have the third prong.
How do you connect a four prong outlet to a 12-2 plus ground wire where both black and white wires are hot?
You don't, you need a three wire to correctly make the connection.
