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.
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.
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.
One option is to use a GFCI (Ground Fault Circuit Interrupter) outlet, which can provide protection similar to a grounding wire. However, it is essential to ensure that the wiring in your house is up to code and that you follow correct installation procedures to maintain safety. Consulting with a professional electrician is recommended to ensure proper installation.
=== === 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.
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.
if you push the button and it starts then it is installed
You can tell the CAT level (or category) of a cable by looking for imprinted markings along the length of the cable. Look for the number preceded by 'CAT.' That is the category of the cable.
it tells you.
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. THis does NOT mean that they are included in the cost of the rental.

There are no online outlet stores. Outlet malls are found all over the US, so depending on where you live, there is probably a local outlet mall in your area.
In order to answer this question you have to tell us where you live. Otherwise I cannot tell you if there would be a jewelry outlet nearby. On the Internet argos.co.uk seems to be a good site.
