When building a house, or remodeling, it is important to work with a qualified, licensed electrician to prevent wiring problems that could lead to a fire. Money spent on the professional could save you thousands in damages and may even save your life. On the face of it electricity seems simple- positive to positive and negative to negative but there are other considerations like resistance as well as properly isolating the electrical components from flammable building materials. Electrical failures account for a significant percentage of structural fires and the cause of such fires is often attributed to the receptacles and accompanying connections in such installations. Given the large number of such installations, this is not surprising. The type of failure that will produce enough energy to cause the ignition of such electrical installations includes connection integrity, however, high resistance connections, as a cause of such fires has not been widely investigated. As electric current flows through a system of conductors and connections, heat is produced. This heat will dissipate properly and the fire risk will be low if conductors have been consistently rated for the on-going current load, the connections have been made properly and individual components are appropriately rated for the application. Variables that increase potential levels of fire risk in such installations include inadequate installation of components, frequent plugging in and unplugging of appliances and current variations that cause vibrations to connections. The impact of each of the preceding factors alone or in combination is difficult to predict. They occur over long periods of time and the symptoms of such faults often escape both installers and users. Their occurrence may be evaluated in carefully designed, prospective investigations. However, when a fire investigator, faced with a wiring system that has undergone significant destruction in a major, structural fire, identification of the impact of such variables – when clues are present - requires great care and patience. Your best bet for preventing fires of this kind is using a licensed electrical contractor or electrician to hand installations and modifications. It might seem simple, positive to positive, negative to negative, but the realist is not as straightforward. There are dozens of factors to consider. If you are not 100% certain that you know what you are doing, consider calling a pro. The money an electrician charges will seem like a bargain compared to the cost of cleaning up after a fire.
