KENTUCKY (1/17/17) — The invisible systems in a home often are taken for granted. When such systems are working as expected, daily life moves along smoothly. However, when a system goes awry, it can negatively impact routines and may create a dangerous home environment. This is especially true when something goes wrong with a home's electrical system.
Faulty wiring is a leading cause of residential fires. Many homeowners, particularly those who live in older homes, might be living in properties that have outdated electrical systems. It also may damage appliances and make it difficult to sell a property in the future.
It can be difficult to gauge exactly when to overhaul an electrical system. Unless circuits routinely trip or lights often dim, homeowners may put off the work. But degrading wires or overextended circuitry can pose a fire risk, so it is best to address electrical systems promptly.
Home inspections may uncover electrical problems. Some homeowners may discover potential trouble while making renovations that require opening up walls or tearing them down, exposing the wires. Still other homeowners learn about electrical systems when they're adding new, large appliances or other gadgets that consume more power than existing items. These devices may continually cause power outages in the house, such as tripping the circuit breaker or popping a fuse.
When it comes time to update the electrical system, it is always best to work with licensed and bonded electricians who have the expertise to work with electrical wiring without getting injured. This is not a do-it-yourself type of job since it requires specialized training.
Electricians likely will recommend upgrading the electrical panel to bring more power from the utility poles into the home. This can include replacing the existing meter and circuit breaker box to allow it to handle more power or replacing items that are obsolete or dangerous.
Many older homes are only capable of handling a minimum number of amps, utilizing just a few circuits. But nowadays, when homeowners have far more electronics in their homes than they once did, increased demand on electricity can overload a circuit (all of the outlets linked on one wire). Tripping a circuit breaker is a safety measure to prevent the wire from becoming overheated and causing a fire. However, in some old systems, the circuit breaker will not trip, and this can be problematic.
Rewiring a home is another step. Wire insulation can deteriorate over time, and new wires may be needed. This can be messy and time-consuming, but it's a small price to pay for safety. When rewiring an electrician also may suggest new outlets. Many home building codes now require outlets with ground fault interruptors, or GFIs, in kitchens, bathrooms and other rooms exposed to moisture. Some older homes may not even have three-pronged outlets, so this will necessitate an update as well.
Electrical systems are the heart of a home, delivering power where it is needed. It is essential to keep such systems up-to-date so they can handle the power demands of everyday life.
