The Main Service Panel

This component of your electrical system distributes the power to all the circuits located in your home. The main service panel—also known as a breaker box or circuit panel—is a crucial component in your electrical system’s safety. When your power goes out, the first place an electrical contractor will check is the main service panel.In the event excessive power is being pushed into a circuit, that circuit will short, causing the flow to break. This is known as tripping a breaker. Older homes may have fuses instead of circuits, so keep that in mind. Finally, it is crucial to understand how service lines feed the main service panel. This means that the power is always live for this component. For an electrical company to provide any breaker panel service, the power company needs to come and shut off the power.

Types of Wires

Within each electrical circuit, you will find several types of wires. For your safety and others in your home, you should have a firm understanding of this. Each circuit will have at least one hot wire. It will carry the current from the breaker box to each individual circuit. Generally, hot wires will be color-coded as typically black or red. Neutral wires are what take the current back to the service panel. Typically, a white insulation casing denotes a neutral wire. Keep in mind that some circuits may not have a dedicated neutral wire. In these cases, there will be only one wire and it will be hot. When in doubt, always contact an electrician for home rewiring services

Common Residential Electrical Problems

There are plenty of issues that could arise in your house’s wiring. Additionally, if you are working with an outdated electrical system, issues can be more severe. These homes have their own set of problems that should be dealt with by a licensed electrician. Generally speaking, though, here are some issues you may run into:

  • Surges caused by lighting, damaged power lines, or faulty wiring
  • Light switches that aren’t operational
  • Overloaded circuit breakers
  • Lights that won’t dim

This list just scratches the surface when it comes to electrical issues. If things get out of hand, A 24 7 electrician can provide the expertise needed to tackle your residential electricity woes.Â

Common Mistakes and How to Avoid Them

Dealing with any system comes with its own set of rules. Electrical systems are no exception. Understanding what to avoid is more than just about making a mistake. It’s about keeping your family safe. Here are some things to be careful of:

  • Never connect wires outside of a junction box. If there is no junction box installed, you should add one and then connect the wires within it.
  • You should avoid loose switches or loosely connected outlets.
  • Don’t cut your wires too short. They should be at a three-inch minimum.
  • Never install a three-slot outlet without a ground.

This list is not exhaustive. There are many electrical problems you should be aware of if keeping things safe is your prime concern. Keep in mind that often you can find a local electrician who offers quality service at a reasonable cost. Consequently, using a licensed electrician for home safety services is a surefire way to keep things safe in your home.

Understanding Residential Wiring in Modern Homes

If you are working in a new home, you have the advantage of having enough amperage—or overall current. This means you are going to have the power necessary to operate modern, power-hungry appliances. A typical 200-amp service can accommodate multiple laptops, laundry equipment and a boatload of electronics. Additionally, modern homes will need little modification if you need to add more outlets or lighting. Even though newer homes are easier to do electrical work in, everything still needs to be updated. For this reason, you should consult an electrical contractor for most jobs.Â

Wiring in Older Homes

As we touched on earlier, older homes are not as easy to manage when it comes to electrical wiring work. Electrical components age, wires corrode and standards change. When working with an older home, you are going to face all of these challenges and more. Often, older homes:

  • Have outdated or out-of-code wiring
  • Use old electrical technology like knob and tube systems
  • May not have the amperage necessary to power electronics

For most old homes, it is better to scrap the old system and install newer components. The risks of working with outdated wiring are not worth the cost of the severe problems that may arise. The only safe option is to schedule a visit from a licensed electrical contractor.
