What You'll Learn
The importance of not leaving cables exposed
Rerouting electrical wiring around a door is a common task for homeowners and electricians alike. While it may be tempting to leave cables exposed, especially around door framing, there are several important reasons why this should be avoided.
Firstly, exposed cables pose a safety risk. Single insulated cables are susceptible to mechanical damage and accidental contact, which can result in serious injury or electrical fires. Enclosing cables in suitable materials, such as metallic or plastic trunking, provides essential protection against these risks. Additionally, exposed cables can be damaged during future modifications to the door frame or surrounding area, which may be carried out by yourself or others, increasing the likelihood of exposure to electrical hazards.
Secondly, in many cases, it is a regulatory requirement to enclose cables. Electrical codes and safety standards dictate that cables must be adequately protected. For example, the National Electrical Code (NEC) Article 760 states that exposed fire alarm cables should be positioned at least 7 feet from the floor to reduce the risk of accidental contact or damage. Below this height, cables must be protected in a raceway. Local building codes and regulations must be consulted to ensure compliance and maintain safety.
Furthermore, enclosing cables ensures a neat and tidy finish. Cables left exposed can be unsightly and may detract from the aesthetics of a room. By using enclosures, extension boxes, and correctly sized lids and endplates, a tidy interface can be achieved, keeping the space looking orderly and well-maintained.
Lastly, enclosures provide peace of mind and reduce future complications. Exposed cables may be vulnerable to the rigours of everyday life, and single insulation does not offer sufficient protection. Enclosures safeguard cables from accidental damage, ensuring the electrical system remains functional and reliable.
In summary, leaving cables exposed around a door framing or anywhere else is hazardous and can lead to serious consequences. By taking the necessary steps to enclose and protect cables, you not only enhance safety but also ensure compliance with regulations, maintain a neat living space, and prevent future complications.

Using a vinyl raceway to secure the cable
A vinyl raceway is a hollow channel that can help manage the wires, cables and power cords of your electronic devices. They are typically made of rigid plastic or metal and can be easily installed to conceal wiring. Before installing a vinyl raceway, it is important to assess your cable management needs, including the length and path of the cables. This will help determine the quantity and size of raceways required.
The first step in installation is to ensure the wall surface is clean and free of dust or debris. Use a damp cloth to wipe down the area and allow it to dry completely for better adhesion. Next, measure and cut the vinyl raceway to the desired length. Remove the adhesive backing and carefully align the raceway with the marked path on the wall, pressing firmly to secure it in place.
Once the raceway is installed, insert the cables into the open channel, ensuring they are neat and untangled. Some raceways may have covers or lids for added protection. Finally, inspect the installation and make any necessary adjustments for a clean and professional finish.
Raceways can be installed close to an electrical source, such as a television, and can be extended in different directions using T-fittings and elbows. They can also be trimmed and painted to match the room's decor.

Drilling holes to accommodate the cable
Firstly, remove the baseboard or moulding beneath both electrical outlets. This will allow you to access the area where you will be drilling. Next, drill holes on an angle through the floorboards. These holes should be drilled in the floor joists to accommodate the cable. With patience, you should be able to feed a wire through the first electrical box, through the first hole beneath the receptacle, up through the second floor hole, and into the second electrical outlet box.
If you are drilling through a wall, you can use thin-gauge metal coat hangers and string to help guide the wire. You will need access from a basement or crawl space below the electrical outlets. Run a new cable from the first electrical outlet to the second through the floor and the basement or crawl space ceiling.
If you are drilling through a wall and do not have access to a basement or crawl space, you may need to consider an alternative method. One option is to cut into the wall surface behind the electrical box and reroute the cable. You can also buy steel angle and install it over the wire for protection. This method ensures that the wire is protected from screws and other fasteners.

The fire hazards of making electrical connections inside walls
Rerunning electrical wiring around a door is a complex task that can lead to serious fire hazards if not done correctly. Here are some important considerations and safety precautions to take when rerunning electrical connections inside walls:
Fire Hazards of Improper Electrical Connections
Electrical fires are a significant danger, causing an estimated 295 deaths, 900 injuries, and over $1.2 billion in property loss in a single year. These fires can start due to various factors, and incorrect wiring is a common cause. When rerunning electrical connections inside walls, it is crucial to be aware of the potential fire risks and take the necessary precautions.
Overloaded Circuits and Outdated Wiring
Older homes may not have the wiring capacity to handle the increased number of electrical appliances used today. Overloading circuits with too many appliances can lead to overloaded circuits and worn connectors, which can cause electrical fires. Homes over 20 years old may need an electrical system upgrade to handle modern appliances safely.
Punctured Wire Insulation
Nails and screws used during home repairs or redecorating can puncture wire insulation inside walls. Even walking on carpets laid over wiring can generate enough heat to weaken the insulation. This damage can lead to electrical arcing, where electricity jumps between connections, igniting surrounding materials and causing fires.
Extension Cord Misuse
Extension cords are a common cause of electrical fires. Using an extension cord with a major appliance can lead to overheating and fires. It is crucial to match the extension cord's capacity to the appliance's needs and never to overload power strips or surge protectors. "Piggybacking" power strips, or plugging multiple strips into each other, is extremely dangerous and can easily start a fire.
Warning Signs of Electrical Fires
Be vigilant for warning signs of electrical issues, such as a burning plastic or rubber smell, a sizzling sound, tripping breakers, blown fuses, discolored outlets, sparks, or charred wires. These signs indicate potential electrical fire hazards and should be addressed immediately by a certified electrician.
Always prioritize safety when rerunning electrical connections inside walls. If you are unsure about any aspect of the process, consult a licensed electrician to ensure that your home's electrical system is safe and up to code.
