On the dryer receptacle the U shaped pin is the ground, designated with the letter G if looking from the back side. Apply your tester to the outside left slot, designated with the letter Y if looking from the back side, and the U ground slot and you should read 120 (nominal) volts. Now apply your tester to the outside right slot, designated with the letter X if looking from the back side, and the U ground slot and you should read 120 (nominal) volts to ground. You should get the same readings, as above, if you test to the bottom neutral slot, designated with the letter W if looking from the back side. If you test from outside slot to outside slot you will get a reading of 240 (nominal) volts.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Can you wire a external and an internal ground together on a drier?
The ground wire should go from the dryer directly back to the distribution panel. An external ground wire is not required. The ground wire that is in the cord set that is connected to the frame of the dryer and the ground wire that is in the feeders coming from the distribution panel, that is connected to the ground terminal in the dryer receptacle, is all that is required to satisfy the code requirement.
Adding a 220 line to panel box for a dryer?
A dryer requires a 30 amp receptacle. This will be to receive a four blade dryer plug. The wire needed will be a three copper wire #10 cable set with a bare #14 copper ground wire. The breaker will be a two pole 30 amp breaker.
Why are you getting 123V at your dryer outlet?
You are probably measuring between the one leg of the 240 volts and the neutral or the ground pin connection. Take the measurement from the two outside blade holes on the receptacle. There the reading should be 230 to 240 volts. Between either of the outside blade holes and the neutral or ground you should read around 120 volts.
Is there an adaptor for a 3 prong to 4 prong plug?
Do you want the bad news, the good news, or the really bad news?* The bad news is that there is not an adapter that you can normally buy. * The good news is that you can buy the parts at your local home center or hardware store to make one. * The REALLY BAD NEWS is that if you do this you stand a very good chance of ...* ** Blowing a fuse or tripping a breaker ** Burning up your dryer motor ** Burning up the wires from which you make it ** Starting a fire and burning down your house or apartmentAND IF YOU ARE REALLY UNLUCKY...* Possibly electrocuting yourself or someone else* Or even killing someone in the resulting fire
On three wire spin dryer cord which color green white?
On a 3 wire dryer cord there is no green wire. The white wire coming from the outlet is connected to ground or the green screw. The black and red wires are the hot wires.
Why are you reading 230v between neutral and hot on a dryer receptacle?
it is a miss-wire, check what voltage you get between ground and the other hot!
Should a 3 wire 250 volt drier be grounded?
Yes, most definitely. Provisions for the ground wire in the dryer receptacle should be used. The feeder cable's ground wire is first grounded to the receptacle's junction box ground screw and then taken to the receptacle's ground terminal. The dryer plug configuration will match up to the dryers four wire plug in cable. When the plug is connected into the dryer receptacle the ground terminals of both devices will match and the ground wire will be continuous from the voltage source at the distribution panel and complete the circuit at the dryer. This low impedance electrical path will conduct any ground fault that could occur at the dryer and trip the feeder breaker of the dryer circuit, there by removing the fault current from the dryer circuit.
You were shocked by a dryer receptacle is there any danger?
Yes there is a serious danger. The breaker should be tripping under this condition and not allowing the frame of the dryer to become electrically energized. It means that the ground wire is missing from the dryer receptacle or the dryer cord is not grounded to the machine. Shut the breaker off to the dryer and remove the dryer receptacle. Look for a bare copper wire. It should be bonded to the box and then to the receptacles U shaped pin hole. If this end is fine check the dryer end where the cord goes into the back of the dryer to make sure the green ground wire is connected to the frame of the dryer. If you don't feel competent of doing this get some electrical help as this condition needs to be repaired before you use the dryer again. If you were shocked and recovered, you will be OK You should report it though because it could kill someone, for example, if they had a heart problem of some kind.

Is there an adapter for a NEMA 14-30 male plug to a NEMA 10-30 female receptacle?
No there is no adapter. Change your old dryer receptacle NEMA 10-30 to a new NEMA 14-30. This will allow you to plug the new dryer cord into the old wiring.Answer for USA, Canada and countries running a 60 Hz supply service.Range receptacle three to fourLook in the back of the dryer receptacle box that is in the wall. The three wires coming in should have a bare ground wire in the cable set. It wasn't brought to the receptacle because there was no place for it on the three wire receptacle. If you find it back there under a screw terminal just add another short piece of wire under the screw and then connect the other end of the short wire to the new ground terminal (G) on the new four position receptacle. The wire should be equal in size to the size of the wire that exists around the ground terminal now. If the house is so old that the dryer cable did not have a ground wire in it the code allows a separate green ground #10 wire to be taken from the breaker panel box to the existing range receptacle. This wire is to be bonded on each end. At the panel end to the ground buss and at the receptacle end around the ground screw at the back of the box unbroken and then to the new four position receptacle ground lug (G).Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How high to install a dryer receptacle?
For convenience I install the receptacle just above the backboard of the dryer. This way if the dryer is to be moved out of its location it can be unplugged before the move is started. Sometimes the dryer is located in a confined space and it is hard to reach down to the floor level to unplug the dryer with out becoming an acrobat.
What are the NEC requirements if a laundry circuit is to be installed in a basement of a dwelling for a washing machine and the dryer will be connected to a 30A dryer receptacle?
== == The washing machine outlet should be ground fault protected on 12-2 wire. The 30 amp dryer circuit should be on 10-3 wire with a ground. Laundry receptacle outlet for washer, 12/2 with ground yes! GFCI required if receptacle is within 6 feet of sink or duplex receptacle rather than single receptacle [but a GFCI isn't a bad idea anyway...Dryer, 10/3 with ground and 4-wire outlet and cord set connection at dryer location! NO NEUTRAL BONDING LINK!1) NEC requires a disconnecting means [plug and receptacle works] if equipment [dryer] is not within sight of the power source [in this case, if the panel is in the garage]2) You were never allowed to use the ground wire to carry neutral current, so you need an insulated white or grey neutral [this means three wire]3] You are not longer allowed to use the neutral jumper at the terminal in the dryer for a chassis ground [with certain limited exceptions - existing ungrounded three wire cable and new dryer] Ground wire goes to chassis.

Can you use 50 amp wire and receptacle on dyer?
It's necessary to look at the dyer to see how much current it uses, which should be on the maker's plate near where the cable enters the appliance. If it uses less than 50 amps, a 50 amp cable is all right.
How do you wire a 4 prong dryer cord to a 3 wire receptacle?
Using a red wire nut hook the 3 wires (of the same color) together with a short piece of wire of the same color. You now have 4 wires tied together. Now take the other end of the short wire and attach it to the outlet on the correct screw Do the same with the other 2 wires Please keep in mind to make sure the wire nut has securely fastened the wires. Loose connections cause heat which cause fire If you do not completely understand this answer please contact a qualified electrician
How do you wire a 4 wire dryer plug into a 3 wire?
You cannot wire a 4 wire dryer plug into a 3 wire outlet for mobile home use - (US NEC) - you must carry all four conductors all the way back to the distribution panel. In a hard wired house configuration, if the dryer is designed to support it, you can replace the pigtail with a three wire pigtail, and connect neutral to ground inside the dryer connection panel. Check your local electrical codes and laws for specific requirements.

Why wont your Electric Clothes dryer turn on anymore?
Assuming your dryer blower does run, then you must have one of the phases dropping out. Check all electrical connections at the breaker or fuse box, dryer receptacle, and wiring going into the dryer. If your blower runs, then your neutral is probably okay. Check one of the "hot" leads. I suspect one has come loose, or wasn't fastened at all.
