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.
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.
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. 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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Will a dryer run but not heat heat if the circuit is hooked up wrong?
Depending on the connection this scenario could happen. The 240 volt heating element of a dryer is connected to the two outside terminals on the dryers terminal strip. Also in this circuit is a thermal cut out that will open the circuit should the internal mechanisms of the dryer get too hot. The motor connection and the controls of the dryer are 120 volts. This means that the voltage is obtained from one of the 240 volt legs and the neutral connection on the dryers terminal strip. This connection is in between the two outside 240 volt connection points on the terminal strip. On a four wire dryer cord the fourth wire is the ground and should go directly to the chassis lug on the dryers frame. Turn off the breaker or unplug the dryer from its receptacle and check your wiring. Red and black wires on the outside terminals on the dryers terminal strip. It makes no difference whether red is on the left or right terminal. The white (neutral) wire is on the terminal between the two red and black or black and red wires depending on how you placed them on the terminal strip. The ground wire of course will be connected to the frame of the dryer. If this is the way the connections are made inside of the dryer it should work. If any work has been done on the wall receptacle make sure that the wire on the receptacle match the wiring inside the dryer.
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.
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.

What are the necessary steps for installing a dryer receptacle box in a laundry room?
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.

What is the proper electrical requirement for a 30 amp dryer receptacle?
The proper electrical requirement for a 30 amp dryer receptacle is a dedicated 240 volt circuit with a 30 amp circuit breaker and a 3-prong or 4-prong outlet.

My 110 washer will work my 220 dryer will work. why will it throw breaker when both are plugged in on separate breakers?
Your 110 volt washer receptacle sounds like it is not a dedicated circuit directly fed from the distribution panel as it should be. It sounds like someone has tapped off of one side of the dryer receptacle hot and neutral terminals and run them to the receptacle for the washer. If true, this would have been done in the back side of the dryer receptacles which is located in the wall. You best get it checked out because it is likely the wire feeding the washer receptacle is a #14 rated at 15 amps and is undersized for a 30 amp breaker. A #10 wire has the capacity to be connected to a 30 amp breaker which you should find the dryer's connection to be.
How can I convert a 4-wire dryer to a 3-wire dryer?
To convert a 4-wire dryer to a 3-wire dryer, you will need to remove the neutral wire and connect the ground wire to the neutral terminal. Make sure to follow safety guidelines and consult a professional if needed.
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
Can a hair dryer trip a gfi receptacle?
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.
