Frequently Asked Questions
What type of electrical wiring is used in commercial buildings?
Daven Electric Corp. uses different types of electrical wiring depending on the commercial building’s specific needs and local building codes. Some common types of commercial wiring include:
- THHN/THWN Wiring: This is widely used for general commercial wiring. It’s durable, heat-resistant, and ideal for wiring installations within conduit systems.
- Metal-Clad Cable (MC Cable): MC cables are flexible, protected by metal armor, and excellent for tight spaces. They’re commonly used in commercial environments to provide reliable wiring solutions.
- EMT Conduit Wiring: Electrical Metallic Tubing (EMT) is frequently used in commercial wiring projects, providing superior protection and ease of maintenance.
- Low-Voltage Wiring: Data, communication, and security systems typically utilize low-voltage wiring, which is essential for office buildings, retail spaces, and healthcare facilities.
Our experienced electrical contractors carefully select wiring based on safety standards, the building’s usage, and energy-saving requirements, ensuring your business remains safe and compliant.
How much does commercial electrical wiring cost?
The cost of commercial electrical wiring can vary significantly depending on a few factors. Here at Daven Electric Corp., we always explain clearly what affects your project’s cost:
- Project Size: Larger buildings or complex commercial spaces will naturally cost more because of the materials and labor required.
- Type of Wiring: Specialty wiring or advanced systems may cost more than basic electrical installations.
- Existing Infrastructure: Older buildings often require additional work, such as rewiring or retrofitting, which adds to overall expenses.
- Labor and Equipment: Highly experienced electrical contractors and specialized equipment will influence your project’s budget.
- Code Compliance: Ensuring your wiring meets New York electrical codes can add costs but is critical for safety and legal compliance.
Generally, commercial wiring projects range from a few thousand dollars for smaller tasks to tens of thousands for larger-scale installations. Contact our friendly team today for an accurate, transparent estimate.
What are the three types of wiring connections in commercial wiring?
In commercial electrical wiring, we typically see three main types of wiring connections that ensure safe and dependable electrical flow:
- Splice Connection:
- Join two or more wires together securely.
- Often done within junction boxes using wire nuts or approved connectors.
- Ideal for extending or branching wiring circuits.
- Terminal Connection:
- Attaches wires directly to electrical terminals, like breakers, switches, or receptacles.
- Usually involves screws, terminal blocks, or lug connections.
- Common in electrical panel upgrades and equipment connections.
- Plug or Receptacle Connection:
- Standardized connections using plugs and sockets.
- Used for easy disconnection, typically found with lighting systems, machinery, and portable equipment.
Our New York City electrical contractors at Daven Electric Corp. carefully select the correct wiring connection method for each job, following strict electrical safety standards and local codes. This ensures your wiring system remains reliable and safe.

What is the difference between residential and commercial electrical wiring?
At Daven Electric Corp., we often explain the difference clearly between residential and commercial electrical wiring to our clients. Here’s the simplest breakdown:
- Power and Capacity:
- Residential wiring typically supports lower power demands, suitable for homes.
- Commercial wiring systems handle higher power loads due to equipment, machinery, lighting, and HVAC systems.
- Complexity and Layout:
- Residential wiring layouts are simpler and designed for standard home appliances and lighting.
- Commercial electrical layouts are more complex. They are often designed by professional electrical system designers and involve detailed plans to meet specific business needs.
- Safety Codes and Regulations:
- Commercial wiring adheres to stricter codes and regulations due to the greater number of occupants and heavier use.
- Residential wiring, while also regulated, follows different, less stringent standards.
- Maintenance Needs:
- Commercial wiring requires more frequent inspections, maintenance, and troubleshooting due to higher demands and continuous use.
- Residential wiring generally requires less frequent maintenance.
Understanding these differences helps property management firms, building owners, and developers ensure safety, compliance, and efficiency.

Can you do electrical work on your own business?
As a business owner, you might wonder if you’re allowed to perform electrical work on your commercial property. In New York, electrical work—especially commercial electrical wiring and rewiring—must typically be performed by licensed electrical contractors. Here’s why:
- Safety and Liability: Commercial electrical projects require specialized knowledge of electrical codes, safety practices, and wiring methods. Improper work could pose serious risks like fires, shocks, or equipment failures.
- Code Compliance: City codes and regulations demand professional oversight for commercial electrical wiring to maintain safety standards and ensure proper inspections.
- Insurance and Permits: Most insurance companies require proof of professional electrical work. Doing electrical work yourself can void insurance coverage or complicate claims.
At Daven Electric Corp., we recommend always hiring licensed commercial electricians for your wiring and maintenance needs. Our experienced team handles all electrical installations, upgrades, and repairs safely, ensuring peace of mind and full compliance with New York City regulations.
