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.

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.
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.
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.
To hook up a three-prong dryer cord without a ground, first ensure the dryer is unplugged. Connect the black wire (hot) to the left terminal, the red wire (hot) to the right terminal, and the white wire (neutral) to the center terminal of the dryer's terminal block. Make sure to secure all connections tightly and replace any covers before plugging in the dryer. However, it's important to note that using a three-prong cord without a ground may not comply with electrical codes and can pose safety hazards.
To hook up a 4-prong dryer, first ensure the power is off at the circuit breaker. Remove the cover plate on the back of the dryer and connect the green or bare ground wire to the ground terminal, the white wire to the neutral terminal, and the red and black wires to the hot terminals. Tighten the connections securely, then replace the cover plate. Finally, plug the dryer into the outlet and turn the power back on.
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.
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.
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.
Yes, a hair dryer can trip a GFCI receptacle if there is a ground fault, electrical short, or moisture present that triggers the GFCI's safety mechanism. It is important to ensure that the hair dryer and the outlet are in good working condition to prevent tripping the GFCI.
To install a dryer receptacle box in a laundry room, follow these steps: Turn off the power to the area where you will be working. Locate a suitable location for the receptacle box near the dryer. Cut a hole in the wall for the box using a drywall saw. Install the box securely in the wall. Connect the wiring to the receptacle according to the manufacturer's instructions. Secure the receptacle in the box and cover it with a faceplate. Turn the power back on and test the receptacle to ensure it is working properly.
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
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.
Reading 230V between neutral and hot on a dryer receptacle indicates a problem with the wiring setup. In a properly functioning system, you should read 240V between hot wires and 120V between hot and neutral. The issue could be due to a faulty connection, break in the wiring, or incorrect wiring at the receptacle. It's crucial to address this issue promptly to avoid potential safety hazards and damage to the appliance.
== == 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.

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.
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.
