Electrical issue can occur from various different methods, some of them minor and others may need to be fixed or replaced by an electrical contractor. If you have an older home, it's possible that power interruptions may happen frequently, such as problems with the lights flickering on and off and electrical outlets may not be grounded properly. In addition, there may be issues with the wire junction box, knob & tube wiring, and even wire clamps. The information below provides details on basic electrical issues that may occur and how to fix them.
The Junction Box
Wire junction boxes prevent live wires from touching each other and possibly creating a fire as a result. The purpose of the junction box is to securely close off the area where two or more wires meet. The junction box is also needed to reduce the risk of possible shock hazards. However, if you have an older home, then it's possible that your electrical unit has not been upgraded to include junction boxes, which means there could be exposed live wires. For this reason, it may be necessary to have your wiring system checked over to verify there are junction boxes installed and they are in working condition.
The Knob & Tube System
Electrical knob & tube wiring systems were installed in homes constructed before the 1950s. The knob & tube wiring system typically contain wire conductors that are separate and wrapped in a thin overlay of material, instead of wrapped in sheath-like cables. Sheathed cable wirings are now used to secure intertwine the wires together and seal them off. The sheathed cable electrical wiring system may be safer than the traditional knob & tube wiring. In addition, the knob & tube wiring method has become almost obsolete because of possible safety hazards, due to missing grounding conductors. If you have an older home, consider having the electrical wiring system looked over to ensure that there are no knob & tube wiring installed.
Wire Bushing And Clamps
Electrical issues may occur if you have missing wiring bushings and clamps, which should be securely located at the entrance point of where the wiring units enter the junction box. If the wires are not covered and clamped off, it's possible that they may become exposed and come apart. Wire bushings and clamps are used to keep the actual wires from touching the junction box. For example, vibrations can occur through your garbage disposal which causes an activity of friction that may cut through the insulated wires. This can also cause active conductors to be exposed as well, which may cause you to get shocked as well.
If you are unsure about your home's wiring system, as mentioned above, consider consulting with an electrical repair contractor.
