When it comes to electrical wiring for your business, you need regular-voltage wires that can run power to your appliances, devices, and anything else you wish to power.
However, many modern buildings also utilize low-voltage wiring, which is commonly used for high-speed internet and the many connected devices we use today.
So, how can you differentiate low-voltage wire from regular wire, and which is best to install on your commercial property? Keep reading to find out.

Comparing Low Voltage Wire & Regular Wire
Low-voltage wires handle less than 50 volts, making them ideal for safe, low-power applications such as low-voltage lighting, doorbells, and thermostat systems.
However, regular wires carry standard mains electricity at 120V or 240V, powering high-demand devices such as appliances and landscape lighting in residential and commercial buildings.
Most wall cable outlets maintain 120V or 240V, but low-voltage wiring does not carry the same current.
What is Regular Wire?
Regular wire installed in homes or businesses is designed to power standard equipment. It’s what runs to outlets and is typically 120V or 140V. All buildings that have electricity will have standard wire run throughout for power.
Most appliances, including computers, TVs, and major appliances, require the voltage carried by regular wire. Devices that you plug into your outlets also use regular wire.
The regular wire was—and still is—the standard in most buildings. However, many things in modern offices don’t need as much power as regular wire offers.
Many buildings now have low voltage and standard wires to transmit power.
Advantages of Regular Wire
- Higher Power Handling: Regular wires are typically designed to handle higher voltage and current, making them suitable for main power distribution and high-voltage wiring applications.
- Versatility: They can be used in a wider range of applications, including residential, commercial, and HVAC systems because of their high voltage capacity.
- Durability: Often built to withstand higher environmental stresses, such as temperature extremes and physical wear.
Disadvantages of Regular Wire
- Safety Risks: Higher voltage wires pose greater risks of electricity shock and fire if not properly installed and maintained.
- Cost: Installing regular wires can be more expensive due to the need for additional security measures like conduit and insulation.
- Complexity in Handling and Installation: Regular wires are generally thicker and stiffer, which might complicate installation, especially in tight spaces or over long distances.

What is Low Voltage Wire?
Low voltage wire is installed in addition to regular wire, and it’s used to power things like WiFi, high-speed internet, security systems, lighting, smart devices, phones, AV wiring, heating and cooling thermostats, and landscape lighting.
Also referred to as structured cabling, low-voltage cable is usually 50V or less. Other common voltages for low-voltage wire are 12V, 24V, and 48V, which is much less than the standard 120V or 140V. Low-voltage wires typically have a larger gauge than regular wire and can be used for lighting fixtures.
Low-voltage systems are the standard for business networks today. Network wiring can be CAT5, CAT5e, CAT6, or CAT6A, with CAT5 being the most outdated and least efficient and CAT6A being the most up-to-date and best-performing.
Networks with fast download and upload speeds require CAT6 high-voltage cables to work optimally.
It’s important to have the most up-to-date wiring for your network; if your structured cabling is outdated, you may not be able to fully take advantage of its features.
Advantages of Low Voltage Wiring
- Efficiency: Low-voltage cables are more efficient because they carry less power.
- Adaptability: It’s easy to make changes or additions to the low-voltage system as your business grows or new technologies become available.
- Cost-effective: Low-voltage cables have lower running costs due to their efficiency and the lower voltage required.
Disadvantages of Low Voltage Wiring
- Fragility: Low voltage wiring is delicate and can only handle about 25 pounds of pull strength, requiring careful handling.
- Complex Installation: Installing low-voltage wiring can be tricky and requires detailed knowledge and skills.
- Initial Costs: An upfront cost is associated with installing additional wiring in your building with low-voltage cables.
Installing Low Voltage Wires vs Regular Wires
You should only be a licensed electrician if you shouldn’tare the one to install electrical wiring in your building.
In most cases, regular wire will automatically be installed in your building. It runs throughout your building and can be turned at 90-degree angles.
If you decide to add low-voltage wiring, installation can become a bit more tricky and should, again, always be done by a professional.
Low-voltage wiring needs to run at least a foot away from regular wires, and the installation should be done parallel to other cabling. Most low-voltage wiring can’t be installed at 90-degree angles, which can also make installation tricky.
Deciding to install low voltage during construction can make the installation process less tricky, but it is possible to install low voltage at any time.
While low-voltage installations are typically simpler and sometimes DIY-friendly, it is advisable to hire a professional for both types of wiring to ensure proper installation and adherence to local codes and safety protocols. Contact us for a free quotation!
FAQs
Are low voltage wiring safer than regular wires?
Yes, low-voltage wiring is generally safer to handle and poses a lower risk of causing severe electrical shocks or fires due to its lower voltage levels, especially for light fixtures and landscape lighting.
For safety reasons, using low voltages on these fixtures is highly encouraged.
How does the installation cost compare to low voltage and regular wires?
Low-voltage installations might be cheaper due to less stringent conduit and insulation requirements. However, the overall cost can vary based on the complexity of the project and the need for specialized transformers or converters.
In Conclusion
Choosing between low voltage and regular wire depends largely on the specific requirements of your electrical project.
Low-voltage wire, with its efficiency and adaptability, is ideal for applications that require less power and pose minimal risk, such as telecommunications or landscape lighting.
On the other hand, regular wire is necessary for handling the higher voltage loads needed for powering household appliances and commercial equipment.
