How do you ground a dishwasher with only 2 wires available?
If it has a metal body you attach a suitable cable to match the ground or earth wire colour in your country ( such as a 6 mm squared cross sectional area ) copper cable with green-yellow ( in the U.K.) insulation colours to the metallic frame of the dishwasher with a cable lug and a brass ( preferably ) nut & bolt. Then using a suitable length of cable to the nearest grounded piece of metalwork such as a copper pipe using a "earth clip" for a copper pipe. These can be bought from electrical wholesalers who supply all electricians or / and electrical contractors.

How do you wire a 20A switch which comes with a neutral wire when only 2 wires are available for the circuit?
You never switch a neutral wire, only hots. hooking both hot and neutral to the same switch will result in a short when the swith is turned on.
CAN'T. Must have 3-wire w/ground. [First off, I want to admit that the wording of this answer is skewed. However, if you read the answer you will understand why. It is techin…ically correct in terms of the NEC. -TJNII] The idiot that wired my house did this. To add insult to injury he connected the hot to one circuit and the neutral to another. I was almost electrocuted because of it. Do it right or don't do it at all. Your negligence may kill someone.
Answer . Yes. . GFCI receptacles do not rely on a ground conductor to work. They sense any difference between current flowing in the hot wire and current returning in the… neutral wire. Under normal circumstances, these two currents will be exactly the same. If there is a difference, then some of the current is flowing from the hot to somewhere else, possibly through a person to ground. This causes the GFCI to trip.. The National Electric code even permits an old 2-wire receptacle with no ground wire to be replaced with a GFCI 3-prong receptacle. No ground wire is used, and the GFCI must be labeled "No Equipment Ground". See NEC Article 406.3(D)(3)(b) and (c). This is the only legal way to install a 3-prong receptacle in place of a 2-prong without running a new ground wire.
If I replace a 2 prong plug with a 3 prong and only wire it with the black and white wire no bare ground should the plug in type testers with 1 red and 2 yellow lights show that everything is fine?
Answer for USA, Canada and countries running a 60 Hertz supply service. If you replace an ungrounded outlet with a grounded outlet, the tester should show an open ground indi…cation. The left light will be the only lamp that will light up. Install either another ungrounded outlet or a GFCI receptacle.. 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 REALLY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Answer . Any house built before 1950 probably only has 2 wires. Black and white. You do not need a ground, that is only to ground the fixture. Hook black to black and white… to white and don't worry about it.
Can you connect 3 wire to 2 wire House wire has black white and ground Appliance has black red white and ground wires?
Answer for USA, Canada and countries using similar 60Hz household electricity supplies . Just by asking this question that shows you are probably not quite ready to take on… this particular task. The safest answer anyone should give you is NO, leave it alone , don't even think of doing this! You may or may not get lucky and receive some more information in an answer here! If you hope to get enough information on this site to be able to do this job properly and safely, please do not rely on getting accurate information about such a potentially dangerous subject. Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you put just one wire in the wrong place you risk being killed by electrocution or you could even start a house fire. How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact location of the appliance you wish to install. If it is anywhere that is subject to water splashes or spray - such as in any room supplied with running water pipes, like a kitchen, bathroom, shower room, etc., or in a pool-side area - in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician. If you don't want to go to your local library or bookstore - to find and read some books about electrical wiring and appliances and how to install them safely, and to find out about your local Wiring Codes and Regulations - then the best advice anyone should give to you is to call a licensed electrician either to do the job for you or to advise you what you may be allowed to do yourself. The appliance needs a 240 Volt supply. The supply wiring described in this question could either be 120 Volt with ground or 240 Volt without neutral. To allow the new appliance to be used safely it needs to be upgraded or replaced by a licensed electrician who would install new wiring and circuit breakers along with an outlet that would all comply with your local wiring codes. Call an electrician to do this job. . IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.
You are hooking a generator to your dryer plug It is a four prong style but only have three wire cable available and smaller generator Which prong should you hook the ground to ground?
Whoa there! You are setting yourself up for an absolute disaster. There is no way to do what you are trying safely OR legally.. If your generator is a small one, it probably …has only 120V output. Your dryer outlet is 240V. There is no combination of wires that will work properly since you could feed only one or the other hot leg.. If you do manage to get it hooked up somehow, you could backfeed your generator voltage on to the dead utility power lines feeding your house. This is quite illegal, and several utility workers have been killed in the past by someone doing exactly what you are trying to do.. Also, when the utility power comes back on, it will destroy your generator and possibly cause a fire.. You NEED to have a qualified individual install a manual transfer switch and move the desired branch circuits to it. then you will have a place all set to plug the generator into, and the interlock feature prevents you from cross connecting utility and generator power.. No offense, but you will hurt someone if you do not get help.. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. . If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized..
How do you wire an outlet with 2 hot and 2 neutral screws with a wire that has only 1 hot and 1 neutral wire along with a ground wire?
The very first thing you do is shut the power off to that circuit if you are going to work on it. A regular duplex receptacle has 5 screws on it. With the receptacle facing yo…u and the U ground pin facing down, the left side (neutral blade, silver screws) connects to the white (neutral) incoming wire. The right side (hot blade, gold screws) connects to the black (hot) incoming wire. The ground wire connects to the green screw on the receptacle Strip and wrap the wires around the appropriate screws. This leaves you two more screws on either side, tighten them snug as no wires go under them. Reinstall the receptacle back into the wall and turn the power back on.
I order to do this all the wire need to be replace with three wire.
How do you wire a light fixture that has a white wire black wire and a ground wire if you only have a white wire and a black wire coming from the wall?
It is strange that a ground is not currently installed. For safety a ground is required. However, the good news is that a ceiling fixture provides little chance of a shock haz…ard except when servicing the fixture. However, the missing ground should be a warning that other things may be wrong with your wiring and you should consider having an Electrician check your overall wiring for issues. It is likely that someone has done some rewiring in your house and they may have screwed up other things. Depending on the age of the home there may not be a ground wire in the box. you can tell the old wires because the have a tarred paper jacket instead of a thermoplastic one. if this is the case just ignore the ground wire it is not required to make the fan function. and unless you are changing the electrical circuit you do not need to bring it up to current code.
12 AWG with a 20 A breaker.
Some older cloth covered wires tend to loose color. Check ohms with a meter between silver screw and ground. It should be zero or thereabouts. NOTE: When checking the ohm…s, make sure the circuit is off. Your ohm meter will be destroyed if you attempt to check ohms of a live circuit and happen to cross the "hot" wire.

Can a ground wire be connected to the white neutral in Clearwater Florida if no ground wire ia available?
Yes, if there in no ground wire that is acceptable on a home with no ground wires.
In Home Electricity
The grounding wire is not intended to be a load-carrying conductor in ordinary use, but rather a SAFETY conductor. Grounding wires are often "one size smaller" than the associ…ated load conductors in the same cable.
In New Electrical Work
Not in the latest edition of the code book. It should be on a 15 amp dedicated circuit.
In Math and Arithmetic
With one interpretation of this question, the answer would be two 120V wires and a ground.
In Modification of Old Electrical Work
With limited information available as to the type of equipment that is to be grounded it is always safe to place the ground wire on the equipments frame. This will not be grou…nding but bonding which will keep all equipment within the electrical circuit on the same potential which should be zero.
