Do you need to Rewire the Electrical System of your Home?

1. Check for Warning Signs

An alert homeowner is a safe homeowner. If you are confused about hiring an electrician for rewiring the old wires in your home, look for the following tell-tale signs of damage:

  1. Frequent blown fuses and bulbs
  2. Regular tripping of circuit breakers
  3. Damaged and exposed wires
  4. Over-fused electrical panel
  5. Constant flickering of lights
  6. Charred outlets and hot plugs
  7. Constant burning smell and buzzing sound
  8. Spark while plugging or unplugging cords
  9. Electrical shock in a few outlets
  10. Old-fashioned Bakelite switches and sockets
  11. Multiple socket styles that indicate fractional wiring changes
  12. Violation of Ontario Electrical Safety Code

2. No Major Electrical Work in the Past

The major indicator for rewiring your home is the age of the electrical wiring system. If the wiring of your home is not changed in the last 25 years, it is time for an upgrade. Old electrical wiring doesn’t take into consideration your current gadgets and their requirements. You may need to rewire the property as well as apply for an electrical service upgrade to keep using your tech-gadgets. When you are purchasing an old home, it becomes difficult to know about the past electrical renovations. It is best to hire a licensed electrician to inspect the property.

3. Existence of Knob and Tube Wiring System

Knob and Tube wiring system is one of the most common wiring systems available in older homes. The electricians used insulating knobs to prevent the wires from coming in contact with inflammable materials. The tubes enabled the wires to pass through wooden joists. The major problem with the system is lack of a ground conductor. It increases the chances of shocks and fires. Also, over a period of time, the rubber insulation breaks down causing problems. The knob-and-tube wiring may not be sufficient for your current electrical consumption and the previous owner may have installed modern wiring with the old one. It is a recipe for disaster and one that needs to be checked immediately.

4. Presence of Aluminum Wiring

In the olden days, aluminum wiring was used in the electrical system of homes. However, the story has changed today. Electricians prefer to use copper wiring because it is a better metal. Aluminum is softer and thus prone to arcing, oxidation and corrosion. If you are concerned about the existence of aluminum wires in your home, you must consult a licensed and experienced electrician immediately. You can either opt for replacing the old wires on the property with superior copper wires or even choose to replacing the old wire connectors and switches with ones that are compatible with aluminum. Alternatively, the electrician can consider the “pigtailing” method. It involves intertwining/splicing one end of a copper wire to the existing aluminum wiring system. The other end is connected to the device outlet.
