How old is your home? Has it been rewired? If your home was made in the early 1900s it most likely has the knob and tube method of wiring used in that time period. Is it safe, or has it been modified, what kind of modern units are you using in your home such as air conditioners, dishwashers and dryers. These are all questions you should be asking yourself if you are a homeowner and want to safely use the electric it the house. I have done some research on this wiring method and will contrast the goods from the bads to see if it should be replaced or if its better than standard romex. First, if there is old style wiring in your home does it last. The knob and tube wire i have messed with has always been aluminum. Its a good conducter, but it is flimsy. If you tug on it just i tiny bit it will bend or adjust in a different position, witch could be bad if a switch is wired behind the wall and you can not see the wire to adjust it. So if it has not been messed with it is usually in decent shape for an example if you put a new receptical in and you have knob and tube wiring it might be weak and break. Standard romex on the other hand is more durable to weathering because instead of clothe it has rubber insulation that can withstand weathering better than cloth. Also its made out of copper wire that is more resistant to breaking. You can bend and straighten the copper wire over and over and it will still be good to use. They also make different types of insulation for romex if you are placing it somewhere that is exposed to the weather. So thats a plus for romex againts knob and tube wire. Secondly knob and tube wiring used fuses verses romex using circuit breakers. A breaker or a fuse has the same concept. If the amps in the circ... ... middle of paper ... ...nt realize what it would be like with out it and kind of take it for granit.Every morning you wake up you use electric weather its your phone alarm or turning on your lights or watching tv. So to me i just have the urge to know about it because i feel that in the right time and place i could make money doing it with everybody wanting more with the new appliances being wired and just everyday repaires. If i were to choose i would pick knob and tube over romex any day but its all about what you prefer and what you like. They both give us electric and is relitively safe if installed the right way. I have been doing research on both knob and tube and romex to see the ups and downs for both of them. It really does come down to what you want and how much electric you are using in your home. This was my research paper on contrast between knob/tube and romex wiring methods.
