Electrical wiring is usually done during the construction of a house. However, if your wiring has become old or if you want to change it when moving in a house you have just purchased, this exercise can cost you anywhere in between $2 and $4 per square foot of area. You can easily calculate the cost of this exercise by measuring the area of your home.
Any electrical wiring that does not comply with the building codes issued by the authorities of the city is considered as faulty. Faulty wiring not only violates the building codes but also jeopardises the safety and security of the building as well as people living inside it. Faulty wiring is the major cause of incidents of electrical shocks, short circuits, and electrical fires in homes and commercial installations. This is the reason why all jobs of electrical wiring should only be carried out by licensed and experienced electricians.
Multimeter is the instrument that is used to test the electrical wiring at any place. Leads from this instrument are inserted into the power source to check if it is giving right voltage or not. If the power outlet is working properly, reading in this instrument should be between 110 and 120 volts. You can buy a multimeter form the market and check the wiring in your home occasionally to see that it is working properly.
If your home is more than 30 years old, it is time to get your electrical wiring inspected and replaced if possible. Also, if the circuit keeps tripping all the time inside your home, it is a sign that your electrical wiring has become old and needs to be replaced with a new one. If lights in your home become dim or flicker when you turn them on, it is a sign of electrical wiring having become old.
Like every other product that is used by us, electrical wiring is also made to last for a certain time period. You cannot continue to use the same old electrical wiring in your home for far too long. After all, the safety and security of the structure and the inmates of a building is dependent upon its electrical wiring. Copper wires can last for 40-100 years while PVC wires can last for around 70 years. You need to get your electrical wiring inspected from time to time by a licensed electrician to make sure they remain safe and proper.
