Exposed components of a power cable

A damaged power cord creates a substantial safety concern both in the home and in the office, but why is this? To understand, we need to examine the role of a power cable. Power cords and connectors are tasked with transferring electrical power from an outlet to a device. As such, they are responsible for transferring large amounts of electricity typically in a safe and controlled manner. Ultimately, power cable damage exposes the internal components of power cords. This increases the risk of electrocution for the user, and can create other complications. 

In the following article we are going to be sharing information on how to properly identify faulty or damaged power cords, as well as a list of prevention tips. Whether at home or in the office, we hope you benefit from the following article. 

Power Cable Damage: What Are The Dangers? 

There are a number of dangers to consider when handling a damaged power cord. The first, and most obvious danger, is naked exposure to electricity. Exposed wires can, simply put, cause electrocution. The severity of the shock ranges, with reactions ranging from muscle reactions, muscle paralysis and physical shock up to burns and even death. This is why it is highly important to identify and repair broken power cords.

Another danger to consider with faulty power cables is the potential for fire. Broken power cords with exposed wiring can create a substantial fire hazard. Not only can the insulation material around the wiring begin to melt if the cord is damaged, but a damaged cord can produce an improper electrical flow to your devices. This can ultimately create power spikes, which can cause appliances and devices to heat up beyond safe and manageable temperatures. This also vastly increases the risk of a fire. 

Finally, a danger presented by power cable damage in a commercial environment is that a facility will not be compliant with HSE’s Electricity at Work Regulations. This states that employers and site owners have a responsibility to ensure electrical equipment and appliances are in a condition which does not create danger. 

What Are the Signs of a Damaged Power Cord?

It is recommended that power cables connected to appliances are checked regularly for power cable damage. Some obvious signs that there is an issue include: 

  • Tears 
  • Fraying 
  • Melted plastic 
  • Exposed wires
  • Burn marks 

If you notice any of the following signs, it is always advised to replace the cord. Failing that, the appliance. If you lack the experience to do this safely, it is encouraged to seek the support of a qualified electrician. 

Prevention Tips

Preventing damage to your power cords is essential to maintaining safety at home and in the office. In order to avoid fraying and general damage, it is recommended that any appliances with long or loose cables are kept away from small children and pets. When storing appliances or devices, it is always best to avoid wrapping the electrical cord around the appliance. Placing cords under carpets or rugs is best avoided, as stepping on them can cause wires to compress. Finally, if any DIY projects are being conducted in your home or office it is important to be mindful of connected appliances.
