The 10-30 receptacle for the dryer has 3 wires white black and bare The volage across bare-white bare-black is 120v Is there any way the bare is neutral or is it ground?
The bare is ground. A bare conductor can only be used as a ground. The dryer doesn't need a neutral, its power flows from one hot (black) to the other (white). A load using only one hot needs a neutral to return to the panel. To make things easier to understand, when using 2 conductor w/ground romex for this (which already contains only black, white, and bare wires), I would color the white wire red with electrical tape on both ends. This way it won't be confused with a neutral.
What else can I help you with?
How do I convert existing 3 wire 220 volt 20 amp breaker wire system to 110 volt from the box to the recepticle?
Assuming there is no neutral: 1) Turn off the breaker. 2) Disconnect 1 of the 2 hot wires from the breaker and connect it to the neutral bar (Recommend phase taping the wire white :) ) Remember which wire you used as the neutral, in a home you will most likely have a black and a red. I would keep the black hot, and phase tape the red wire white. If it's not long enough you can wire nut another white wire onto it to make it reach the neutral bar. 3) Leave the breaker OFF, at the receptacle, change it to a 120 volt receptacle. Take the wire you made the neutral, and connect it to the white screw on the 120 v receptacle, and take the black to the hot. Ground to the ground screw. Make sure you phase tape the red wire at the receptacle white as well. 4) turn the breaker on 5) test the receptacle with a meter or receptacle testing device for correct wiring.
What happens if a fuse is connected into the neutral wire?
In North America the neutral wire is never fused. This is because of the three wire circuit that uses a common neutral. If there are two loads connected across a common neutral circuit and the neutral opens a 230 volt supply will be impressed across both loads as they are now in series with the supply. If both loads were balanced then the voltage drop across both loads would be equal. Dropping 120 volts across each load. Where the problem arises is if the two loads are not balanced and voltage drop goes higher than the manufactures recommended voltage, then the connected device could burn out.
Why would an electric receptacle have 3 hot and 3 neutral wires With one set of wires screwed into the sides of the outlet and the other two sets pushed into the back?
no you have to improperly install it....... :P Shut off the power to the receptacle. Now remove the three black wires from one side of the old receptacle and twist them all together with your pliers. Make a short pigtail 6 inches long, same colour and wire size. Now twist this pigtail into the other three wires. Hold all four wires together with the appropriate size wire nut. Do the same with the white wires. Push all the wires into the back of the receptacle box. Connect the two pigtail wires to the new receptacle black wire to the brass coloured screw, white wire to the silver coloured screw. Screw the new receptacle back into the box, install cover plate, turn the power back on. Done deal.
Where is the problem if you have 240V on your 120V outlet and 120V on the neutral?
Someone has wired 240 volts into your 120 volt outlet. If you have 240 volts you need a specially configured outlet so that a standard 120 volt plug cannot be inserted. If you have this situation you would see 120 volts to ground and not neutral. Sometimes if you don't look carefully an outlet will look like the standard 120 volt variety but it isn't. One of the slots is horizontal and not vertical although there may be a small vertical split. 240 volts doesn't just magically appear. What you are describing is on purpose. If it really is 120 volt receptacle you need an electrician to put in the proper receptacle or re-wire the circuit.
With machine in neutral neutral light doesn't come on and electric start don't work?
Switch for neutral broken or not in correctly. It may operate a relay. Find it and see if it comes on and off with you switching the machine out of neutral and back. If it is fused check that. You can put your meter across the open fuse and watch the meter as you switch.
When measuring voltage across a receptacle you read 120 v across black and only 20 volts across white wire?
the white wire is your neutral side (ground usually), the small potential you're measuring is bleed current
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

Voltage across Neutral and earth for a 3 phase auto transformer?
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
How do you stop appliance plugs from slipping out electrical socket?
Plugs should fit snug into receptacles. If they do not then it is time to change out the receptacle for a new one. Loose plugs in receptacles cause heat due to having a higher resistance across the plug blades and the receptacle slots. Tight plugs have a lower resistance and thereby reduced heat on the blade/slot connection. The cause of many fires have been attributed to this worn receptacle condition.
Why there is zero volt across neutral earth of isolation transformer?
Geez, because it is just that; A NEUTRAL EARTH, there should be equal potential on each side, therefore no current flow, and no voltage.
Why black wire and white wire both have power?
In the US, house wire has the BLACK wire connected to the HOT phase of the service input. The WHITE wire is connected to the NEUTRAL of the service input. Normally, both BLACK and WHITE wires are each connected to the 2 LOAD terminals. It is also normal that the WHITE service wire is connected to the wider spade outlet receptacle. The BLACK wire would then be connected to the shorter or narrower outlet spade receptacle. In wired screw lamp circuits, it is normal to wire the BLACK service wire to the center pad of the lamp socket and the WHITE wire to the screw shell of the socket. In switch circuits, it is normal to wire the BLACK service wire to the switch. The HOT service circuit is then opened or closed by the switch. Measuring voltage on your neutral means there is a break in neutral. If the neutral is broken you will measure voltage across the break or from the break to ground. Under this scenario you will measure the same voltage as you do on your hot wire and your load should not be working. Measuring voltage on your neutral less than on your hot wire may mean you have a problem where your neutral is supposed to be bonded to ground in your main service panel. In this scenario your load may be working but you need to check the bonding connection.
What happen if you apply triangular input to transformer?
there will be no neutral point in the circuit and high voltage will be across the transformer coils
What was the effects of the sinking of the Lusitania?
The German march across neutral Austria was a factor in drawing England into the Great War.
Why is it that when you touch the neutral in a box that is not connect to the panel cause the test light to come when touching the power wire?
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
