Electrical Wiring Basics You Should Know Before Renovations

According to the National Fire Prevention Association, electrical delivery and lighting gear are the fourth primary cause of house fires. A few basic precautions can greatly reduce the risk of such fires. To ensure that your house is not at risk of a fire, have the electrical wiring inspected.

It is a general misconception that just because a house is old its electrical wiring is not safe. It is also important to note that the average life of electrical installations is around 20 years. The amount of usage and quality of materials also play a vital role in the life of electrical wiring.

Homes under ten years old should get an inspection done every ten years. Homes having older wiring should have the house inspected more frequently. An inspection is recommended every three to five years. This is not a rule of thumb, just a guideline. Needless to say, if major renovations are done to a newer home, then the electrical burden will increase. In this scenario, the wiring should be inspected accordingly. You don’t want to put additional load on existing circuitry only to find the wires can’t withstand it.

Every house of any ages need do electrical wiring or rewiring

Does Your House Need Rewiring?

The average-sized home constructed in the mid-sixties typically used panels with 60 amp capacity. That was fine back then as the electricity requirement was not that great. Modern life has increased the demand for electricity with all types of gadgetry. Modern conveniences like specialty coffee machines, microwaves, security cameras, laptops, and a host of monitors all put extra load on wires. The average-sized home is now equipped with fuse panels ranging in capacity from 100 to 200 amps.

While whole-house rewiring may be unnecessary, some typical signs that indicate trouble is brewing include:

  • Burning odor: If there is a continuous smell as if something is on fire, and you can’t pinpoint the source. Immediately shut down the power from the circuit breaker and find an electrician. Electrical burns have a characteristic odor of a fish.
  • Charred or tarnished switches or sockets: Any changes in the color of sockets and switches can be an indication of teeny fires. These can be due to loose joints within the socket. But don’t be overconfident if there is no discoloration. Similar fires can also occur further inside the walls which are not visible.
  • Repeated blowing of fuses: Random and recurrent fuse blowouts can be indicators that you need to check out the house rewiring.
  • Lights flickering: A rare light dimming once in a while does not indicate a problem. However, if it is a regular thing occurring in different parts of the house, then it must be investigated.

Periodic checks are necessary even when there are no indications of wiring problems. Different localities have varying electrical codes and it is necessary that your house meet these. Some other circumstances which may require inspecting the whole house rewiring include:

  • Loose outlets
  • Sizzling sounds
  • You find you have to use an excessive number of extension cords.
  • The addition of new appliances may burden the current setup.
  • The home is fitted with aluminum and not copper wiring.
  • The underground is fitted with two-prong outlets instead of three.
  • If the house is over 40 years old.

Electricity is expensive, rewiring can make your home energy efficient and which saves money in the long run. It becomes easier to implement the latest ‘smart’ technologies. While today’s appliances are more energy-efficient, old wiring could be inept at providing correct wattage. Upgrading electrical wiring can deliver the correct wattage. Other benefits include

Signs That Need Rewiring when Renting or Purchasing

You can even ask to take a look at the fuse panel when viewing the property. If the fuse box is old-style continuing ceramic fuses, the wiring will require major upgrading. If the sockets and switches are of different styles, this can indicate partial rewiring. Wiring running on the surface along board skirting or wall corners is also an indicator. Round pin sockets are another dead giveaway.

Beware of Aluminum Wiring

A lot of the houses constructed in 1965 to 72,  frame used aluminum wiring instead of copper. According to the U.S Consumer Product Safety Commission, aluminum wired homes are 55 times more prone to fires than copper. Now aluminum is an excellent conductor, no issue there. The problem lies in the connections. Over time the connections become loose, as the gap widens the risk of overheating increases. Overheating is a potential fire hazard.
