For a US 3-prong plug, a smaller slot should be hot, the longer slot should be neutral, and the screw that holds the plate on should be ground. Cheap, inexpensive testers are available at hardware stores.

What is importance of a polarity test?
HERE'S AN EXAMPLE: IF THE POLARITY IS BACKWARDS AT A LIGHT FIXTURE THEN THE HOT (120VOLTS) WILL BE THE OUTSIDE OF THE LIGHT BULB SCREW SHELL AND THE MIDDLE PRONG INSIDE THE SOCKET WILL BE THE NEUTRAL -- THEREFORE WHEN YOU CHANGE THE BURNT OUT LIGHT BULB YOU WILL GET SHOCKED BECAUSE THE SCREW SHELL PART IS HOT!! IF WIRED CORRECTLY YOU WILL NOT GET SHOCKED BECAUSE THE HOT (120VOLTS) WILL BE INSIDE THE SCREW SHELL ON THE PRONG AND YOU WON'T BE TOUCHING THAT PART WHEN YOU CHANGE THE LIGHT BULB!!
When the hot and neutral are wired backward is reversed polarity?
The assumption here is that you're refering to a standard A/C (alternating current) circuit such as those found in the average household or business. In a typical household the power supplied by the power company actually reverses polarity 60 times a second (60 Hz), hence the term alternating current (A/C). In Europe the standard frequency or Hertz (Hz) is 50 at 220 volts. The U.S. standard is, of course, 110 VAC at 60 Hz. So, in answer to your question In most systems you have a 0 volt potential *neutral and a 110 or 220 volt potential *hot, when this gets wired in reverse safety problems can arise, such as a nasty shock when touching grounded equipment.
How do you wire the last fixture in a parallel circuit?
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
Would a relay be wired differently for a sourcing and sinking output module?
Yes. For sourcing output, the relay coil is wired to (common or ground) and the output terminal. For sinking output, the relay is wired to (voltage supply or hot) and the output terminal.
Why we don't get shock if we touch neutral wire..we need two wires to close circuit pH and n when circuit closes current will flow around the circuit and one wire gets shocked other not why?
We don't get shocked when we touch neutral and ground because neutral is grounded back at the distribution panel, so the effective voltage between neutral and ground is very low. It won't be zero, because there is current flowing on neutral, causing a voltage difference between the load and the distribution panel, but it is low enough, assuming there is no malfunction, to not cause a shock.In the case of touching hot and neutral, or hot and ground, you will get shocked because there is line voltage between hot and neutral, and because neutral and ground are connected together, there is also line voltage between hot and ground.Note, however, that connecting a load between hot and ground is a violation of the code and the intent of the design, because ground is not rated to carry current except in short term fault conditions - you must always connect a load between hot and neutral, or between hot and hot, as the case may be.
How do you wire for reversed polarity?
the hot and neutral are wired forwards the ground and neutral are wired backwards
Is the ridged wire neutral or hot?
If wired properly the ridged wire is the neutral.
Is black the neutral wire?
no in resd. it's hot normally but if wired oppisate 2006 irc code
A reversed polarity is when the hot and neutral are wired backwards?
Yes in AC circuits the terminology reversed polarity means the hot and neutral are reversed to what they should be. In DC circuits reversed polarity means that the positive and negative terminals are reversed to what they should be.
Which is the hot in a two prong receptacle?
The smallest slot is the hot side the larger slot is the neutral slot assuming the outlet was wired correctly.
What happens if you wired your circuit backwards?
Everything will flow backwards
Hot wire in a home electrical system?
If the home was wired properly the black or red wire are hot the white is neutral and the green is ALWAYS the ground
How do you convert a plug in fixture to a hard-wired fixture?
Disconnect it from the hard wired source and install a male plug on the fixture. Small blade is black hot, wider blade is white neutral.
How is it wired or terminated to a phase if all circuits are on the same phase or hot legit would be limited to one neutral?
The question makes no sense.
When was Hot Wired Monstertrux created?
Hot Wired Monstertrux was created in 1993.
Can a hot neutral reverse plug cause a fire?
A reversal of the hot and neutral wires in a wall outlet may not cause a fire, since there is no electrical connection between them. There is a potential for a fire when a device, equipped with a three prong plug, is inserted into this improperly wired outlet. The use of outlet status plugs with luminous indicators help identify improperly wired outlets.
Why is neutral line needed in home electricity?
A fuse is NOT fitted in the neutral phase of single phase domestic power supply. The fuse is fitted in the LINE (also mistakenly called Live). If you have checked and found that the fuse is in the neutral, something is wrongly wired.
