When wiring 4 prong plug for 220 has W X G and Y what goes into the X and Y?
On a 240 volt outlet, such as a dryer outlet: G is Ground, W is Neutral, X and Y are the two Hot legs.

A fork
Should old wiring be replaced?
There is no requirement to replace old wiring unless new changes are being done to an old circuit that does not meet current code, in this case all the old wiring in that circuit must be replaced.It is entirely up to you if you want to replace old wiring or leave it as is (even if it looks unsafe) when no new changes are being made to the old circuit (e.g. you open a wall to do plumbing work and find antique "knob and tube" wiring with insulation problems - you do NOT need to replace any of this old wiring if you did not change its circuit in any way).Many houses in this area have unsafe 2 prong outlets installed in the 1950s that were designed for use interchangeably on 115V 15A and 230V 8A circuits, but their design allows 115V 15A, 115V 20A, or 230V 8A plugs to be inserted without the user knowing they are plugging into an incorrect circuit. But unless something else is changed on a circuit containing these unsafe outlets they may all be left as they are, but every one of these unsafe outlets on the circuit must be replaced with safe 2 prong if anything is changed (3 prong if the circuit is upgraded to 3 wire grounded wiring).About the only thing that could force rewiring the entire building is replacing an old screw in fuse box with a modern breaker box, as this changed to feed end for all circuits.----------------------------------------------------------------------------------------------------------------------------------------------If the wiring has rubber insulation for the conductors you should definitely replace it with modern pvc-based wiring. To protect your electrical outlets and appliances - and also for safety reasons - you should also upgrade the breaker box. If you have old wires which are made of copper that has pvc-based insulation you can leave them as they are but only if they are still in good condition. If the wires are made of aluminum or if they don't look safe - for instance if the insulation is damaged - you should replace them immediately.AnswerOld wiring may be safe if left alone, not overloaded or abused, and was originally "up to code". However, old rubber insulation with cloth coverings can become brittle and literally turn to dust if jiggled. This often occurs in overhead lighting outlets where heat from lights has dried and damaged the insulation. These old installations must be replaced if they are to be touched in any serious way (e.g., undoing clamps or other fasteners), otherwise they become unsafe. In other words, you should not simply pull out the old fixtures and devices and install new ones; you will need new wiring, and if you're getting new wiring, you should (must) get new circuit breakers.You can expect your main electrical panel and meter to last 30 to 40 years before they start to need to be replaced. The wiring in the wall can last a bit longer but when it gets to be 50 to 60 years old you're better off replacing it if you can.AnswerIn the late 1940s a type of cable called "Romex" was introduced in the United States, using PVC insulation for the individual copper conductors with a paper wrap and braided fabric overwrap. It is usually black or silver in color. This type of wiring is still safe today, although early Romex cables didn't contain a third earth ground wire, as required by current electrical codes. Houses with this type of wiring usually have outlets with just two slots, lacking the third hole for 3-prong plugs, although sometimes homeowners have replaced the outlets with the 3-prong type in violation of the National Electric Code (NEC). Current Romex cables have a third copper conductor that connects to earth ground and the outer jacket is molded PVC plastic instead of braided fabric.Take a look at your fuse box or breaker box. If it still contains the old screw-in fuses, chances are that the wiring in the house is outdated and should all be upgraded to modern Romex or "NM" type cable.
What does prong mean?
Prong is a point as the tine of a fork.Edited: each of two or more projecting pointed parts at the end of a fork. pierce or stab with a fork:pronged
Can one convert a two prong outlet to a three prong outlet?
Yes, provided that you have a ground wire in the box and that the ground wire is properly connected in the electric panel.
Wire connected to the rounded prong in a three prong plug?
The equipment grounding conductor is attached to the rounded prong in a three prong plug. Electrical work is dangerous, call a qualified electrician to install. Improper wiring could lead to personal property damage, you or someone else being injured or killed!
What would happen if elctrical plugs only had on prong?
If electrical plugs had only one prong, nothing would happen. Electricity would not complete a circuit. Nothing would work.
How do you install a fisher snowplow four prong solenoid?
No
Can you take a CPU power cord and operate your Boflex Treadclimber if the plug fits or are there different 3 prong plugs?
There are many types of three prong plugs through out the world. These three prong plugs are used for many different voltages and amperages. To answer the question, the world location or amperage and voltage should be stated from the equipments nameplate. This will give an indication of the plug that is in question.
Will a stereo from a 1999 Honda Fit in to a 1995 Honda?
The wiring harness from the 1999 stereo has a 21 prong plug and the 1995 has a 14 prong plug you can purshase a harness from Honda but it has to be hadrwired to the exsisting wiring but don't screw it up, go to Honda and get a wiring diagram for the both of them to match up the wiring you need to make it work.
Do 3-prong cords have difference requirements.. I want to buy a used stackable washer drying and install it where my old stackable was. If the funking plug fits the outlet - am I good?
All three prong dryer cords should fit all three prong outlets. Dryer and stove plugs are different but as long as someone didn't use one in place of a dryer cord, there isn't a problem.
What is involved in running a 240V dryer line if you have a regular 120V line now?
You will have to install a double pole breaker in the fuse panel and then run new wire (10/3) to the location of the dryer and install the proper plug. You will need a 4 prong plug; the older 3 wire plugs no longer meet code for new work.
I have this lamp that has a weird power cord. There is one flat normal prong and one round prong. Like a combination of US and Euro plugs. Does anyone know which power cord to use.?
It could be a loudspeaker polarised plug.
What is wrong if you changed a four prong to a three prong and the dryer is not heating?
My question is WHY did you replace a four prong dryer plug with a three prong! 220 volt Electric dryers require two hot legs, a neutral and a system ground wire. Sounds as though you shunted one of the hots or the neutral. You need to install a four prong plug of the same configuration and wire it exactly as the original.
Replace sentra CD player?
You'll find access to the stereo by removing the ashtray and all screws along the panel enclosing the stereo. You may find it easier to remove the panel enclosing the shifter for more clearance. With the stereo screws removed, disconnect antenna wire and squeeze to disconnect plugs to stereo. You'll save time if you check your new stereo antenna plug. A Nissan has a 2 prong and most stereos have a single prong, which requires an antenna adaptor. If your stereo did not come equipped with the matching plugs to use your existing Nissan stereo plugs, you can purchase one cheaply at your local Walmart and wire in into the stereo wiring.
On a 2000 Toyota Tundra is there a performance gain if you use iridium spark plugs instead of OEM?
No. Toyota plugs need the 2 prongs. Iridiums only have one prong which will not work. Try Bosch if you'd like.
