Which prong of an outlet is live?
Looking at a duplex receptacle the right smaller slot is hot, the left larger slot is neutral and the u ground is ground.
Is the neutral wire on the left of the electric plug?
normally, Yes . because the electrical code doesn't require that the receptacle must be installed so that the grounding slot on the bottom, just in case, somebody put the plug "upside down" the right one should be neutral
Can you plug a 2 prong plug with the same size slots into a 2 prong plug with one slot larger?
Yes, the larger slot is a polarity slot that is supposed to connect the plug in device to the neutral wire. If the device is a lamp it would make the shell of the lamp the neutral wire connection and the center pin the "hot". If the two wire plug has a moulded plug on it, look for a tracer on the devices power cord. It will be a raised rib or a white tracer on the conductor that is the neutral. Position the two blade plug into the receptacle with the identified conductor into the larger slot, this will give you the proper polarity configuration that the manufacturer recommends. New plugs (caps) today all have a ground pin connected to them and can only connect to the receptacle in one position.
When you encounter a four-slot receptacle in a residential laundry room?
It allows for a separate equipment grounding conductor
Which leg is neutral in a polarized plug?
In a standard 15 or 20 amp receptacle (plug), with the ground in the bottom position, the neutral wire goes to the left side of the receptacle as you look at the front of it. The hot wire goes on the right side. Note: the screws to clamp the wire are colour coded. The neutral goes to the silver coloured screw and the hot goes to the brass coloured screw. The silver/brass colour coding does not apply in the UK, but the neutral pin is still on the left. With the ground in the bottom position, notice the heights of the two parallel slots of the receptacle. The taller (or wider) one - on the left - is the neutral, and the shorter one is the hot side. Think of it from a safety point of view: a person is more likely to accidentally touch the bigger slot, so make that one safer than the shorter one.

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.
Which slot does electricity flow in a wall circuit?
Answer for USA, Canada and countries running a 60 Hertz supply service.In a duplex wall receptacle, with the U ground pin at the bottom, the "hot" blade hole is the smaller of the two blade holes located on the right side of the receptacle. The blade hole on the left is the return neutral connection point.
What color wire is attached to the narrowest slot in a duplex receptacle?
I do not know what you mean by long slot. The bare ground copper wire connects to the green screw or the ground screw. The black wire attaches to the copper or gold colored screw and the white wire connects to the silver or chrome screw. Both the gold and silver screws are on the side of the outlet. The ground screw will be on one end of the outlet.

How am i getting 240v between hot and neutral I recently moved into a new home and my washer dryer receptacle was getting 240 from hot-hot 240 between hot1-neutral and 0 between hot2-neutral... help?
I presume that you are testing the receptecle. If so and you are probing one hot lead and one of the 2 neutral leads the receptecle is wired incorrectly. Present day 4 slot receptacle have 2 nueetrals and 2 hots. 110v should read over both hots to groun, and 240v between the 2 hots. Hey Steve its actually a 3 wire plug, the older style and the receptacle is wired properly, i tested it at the panel and saw that there was the same problem. There are 2 panels one is full the second has only two things plugged into it (one being the receptacle) and i still only get 240 of a single lead right out of the breaker.. any ideas? the other breaker on the same panel is doing the same thing ANOTHER ANSWER My suggestion would be that you test each slot with a different ground (not the ground or neutral slot, but perhaps a grounded electrical box or nearby cold copper pipe). If you read 120V on your neutral/ground slot, it's connected to one of the 120V legs (the one you read 0V on before) and needs to be rewired. For safety, I'll reiterate - the reason you read 0V across the "hot2" and "neutral" slots is that they are in phase and at the same potential, NOT because they are dead. If you read 240V across ground and any one slot, you've got a bigger problem than a dryer receptacle. I highly doubt this is the case. In all cases, if you aren't absolutely sure of yourself, get a professional involved. Matt Kramer - Madison WI mfkramer@wisc.edu

What if you did get paint inside an electrical outlet inside the slot and that outlet is no longer working?
The simple fix is turn the power to the receptacle off, change the receptacle out for a new one. Re energize the circuit and you are good to go.
Which slot of an outlet is hot?
The larger of the two is neutral, smaller is hot.
