What you term as a four wire cable is known as a three wire cable in the electrical trade. The ground wire is not counted in the cable set as it is not a current carrying conductor. Turn the power off to the circuit in question. Remove the three prong outlet from the junction box. If you see a red, black, white and bare ground then you have a three wire cable feeding the receptacle. If this is what you see and the purpose of this question is to see if it can be changed to utilize a new four blade recepticle then the answer is yes.
What else can I help you with?
How do you test for groung on a two prong outlet?
Buy a tester. They are very cheap and will tell you at a glance if the outlets are wired correctly. The only other way is to remove the outlet and look see. But if it is a 2 prong outlet with no ground hole then it does not have a ground.
Is there a plug under the dash to wire a brake controler on a 2002 durango if so were?
It all depends on if your truck came with a factory installed tow package. If it did the hook up is in the area by the steering column. The way you can tell is look at your hitch and if it has a 7 blade outlet that has a cable that goes back into the chasis you should be good.
Is there an inexpensive and safe way to convert 2 prong outlets to 3 prong without rewiring your house?
You can convert your 2-wire ungrounding outlets to 3-wire grounding outlets by installing a GFCI receptacle in place of the 2-wire receptacle. The GFCI will be a 3-wire receptacle. In addition, if you replace the first receptacle in a series with a GFCI, you can protect all receptacles downstream of the first one by wiring them on the LOAD side of the GFCI. Once this is done, the 2-wire receptacles downstream may legally be replaced with 3-wire receptacles. They must be marked "No equipment ground", and there may not be an actual grounding conductor installed between the GFCI and the protected devices. You can easily convert a 2 prong to a 3 prong by just replacing the outlet. This will not give you the protection of a grounded outlet as there is no ground wire to connect. I know it is expensive but if you plan on staying in this home, have it rewired, for the safety of your family. The first thing u need to know is which wire is the neutral. If u know which is the neutral u can use that one for the ground also, consequently making a 2 prong into a 3 prong. I seen an electrician do this. Get a "neon tester." This is a neon bulb with two wires coming out of it. Take the screw that holds the cover plate onto the outlet off, and set it to the side. Then plug one wire from the tester into the right-side slot on one of the outlets, and one wire into the left-side slot. The tester should light up. (We did this to make sure the tester works. Sometimes they don't.) If it does, pull the wire out of the left-side slot and stick it into the screwhole. If it didn't light up, stick the wire back in the left-side slot then pull the wire out of the right-side slot and stick it in the screwhole. If it lit up on either occasion, you have a ground going to the box, and you can legally put a three-prong outlet in without rewiring. I tell you this because at one time, they used to wire houses this way--in places like the kitchen and bathroom you needed three-prong outlets, but in bedrooms you only need two-prong, so they'd use outlets and wiring that grounded the center screw. If you really NEEDED a grounded outlet, you bought one of those little 2-prong to 3-prong adapters and ran the screw through the tab to ground it. If you don't get a light on either position, don't put a grounded outlet there.
How can you tell if a 3 prong outlet is grounded?
=== === Tie the bare ground onto the ground screw in the back of the box then tie green wire from outlet to bare ground with a "wire nut", also known as a "marrette", or with an equivalent kind of secure electrical connector.=== === If you must go with a 3 prong outlet, ground the box. I would recommend a 4 prong outlet as it meets modern code and is safer.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.
What can I do if a prong is broke off of my diamond setting?
If a prong breaks you'll need to bring it immediately to a jeweler to have it reattached. Usually you won't be able to tell that it's been broken.

Could you tell me the meaning of cableinternet ready in a rental apt?
it means that the connections for cable TV and internet are already installed. that being said, not all internet is created equal. "internet" could merely mean a phone connection, or it could mean cable modem or high-speed modem ready, depending on the type of connection installed. Check before purchasing a modem.
