Answer for USA, Canada and countries using similar 60Hz household electricity supplies The narrower of the two prongs, which corresponds to the brass colored screw, is hot (red or black wire). The wider prong, which is the silver colored screw is neutral (white wire). The round prong, which is the green screw, is ground (green or bare wire). If you have to ask this question, you should get someone with electrical experience to help you! IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator
to insure the circuit is, in fact, de-energized.

Which supply has polarity AC or DC?
DC has polarity, while AC is constantly reversing in polarity.AnswerWhile the previous answer is quite correct in the sense of 'positive' and 'negative' charges, it's worth pointing out that 'polarity' has a second meaning in a.c. systems. In a.c., the term 'polarity' is used to describe the correct connection of the supply's line and neutral terminals. For example, with an Edison screw lamp holder, to remove the risk of shock, it's important that the line conductor is connected to the centre terminal, and the neutral conductor is connected to the outer terminal. If this has been done correctly, then we say that its 'polarity' is correct. Similarly, if the terminals of a socket outlet (receptacle) are connected the correct way around, then their 'polarity' is correct. Testing for the correct connections in an a.c. electrical system is called a 'polarity test'.
Can reverse polarity burn a tv set?
If, by 'reverse polarity', you mean the accidental reversal of the line and neutral conductors at the socket outlet or receptacle, then the answer is no.
Can you add a 110 outlet from one leg of the 220 wiring?
Yes but I would not advise it. Get 110 volts somewhere else.
What is the use of polarity test?
I will assume that your question is in reference to CT and transformer polarity.In the case of a CT (Current Transformer) they have to be installed in the correct direction for proper metering. The polarity check is used to verify that they are installed correctly and that the polarity marks are correct (if the CT has them).In the case of a transformer there are two types of polarity, additive and subtractive. If you are paralleling transformers you have to ensure that they are the same type polarity in addition to other attributes.Hope this helps.Alternative AnswerIn a new electrical installation, a polarity test is conducted to ensure that socket outlet terminals are correctly wired (line really is line, neutral really is neutral, and the protective conductor (earth/ground) really is protective conductor. It's also important, for example, that the centre pin on an Edison Screw lampholder is connected to line, and not to neutral.
Will an ac motor run backwards if polarity is reversed at the outlet?
No, unless it is a three phase motor and you reverse only two of the phases.

What is power available from 110 VAC outlet?
Any where from 110 volts to 130 volts alternating current is available from a 110 VAC outlet.
What is the highest btu ac that can be plugged into a 110 outlet?
I work At sears the highest BTU's we have is 15,000 that will use 110 outlet
Do you need a 110 v power strip to plug into 110 v outlet?
Nominally 110 to 120 volt power strip is okay to connect to a standard outlet.
Can a 120 hair dryer work with a 110 outlet?
Yes - a hair-dryer rated at 120 volts will work in a 110 volt outlet.
Can reverse polarity burn a tv set?
If, by 'reverse polarity', you mean the accidental reversal of the line and neutral conductors at the socket outlet or receptacle, then the answer is no.
Can you plug In a 220 volt to a 110 outlet?
no
Which is correct in 110 Deer Street or at 110 Deer Street?
"At 110 Deer Street" is correct.
How many amps in standard 110 outlet?
15 amps
240V to a standard outlet?
What is your question? A standard outlet is 110V. A 220 outlet is shaped different so that you know it is 220. You would never run 220 through a 110 outlet.
What causes reversed polarity in a 110 volt receptacles?
Improperly wired receptacle is the normal cause.
How by looking at a socket can you tell the difference in a double or single pole?
Single or double pole is usually a switch. 110 or 220 on a plug, 110 is usually a double outlet. 220 is usually or always a single outlet. Design of the outlet will vary depending on what is plugged into it. The slots can be 1 vertical and 1 horizontal. Both slots can be at an angle. If a regular 110 cord will not plug into an outlet, good chance it is a 220
