A simpler, smarter way to power your space.

If you’ve ever dealt with long conduit runs, last-minute layout changes, or surprise code issues, you know traditional electrical installs can get complicated. That’s where modular wiring comes in.

Modular wiring systems offer a faster, cleaner, and more adaptable way to wire commercial and industrial spaces. Instead of building every circuit from scratch on-site, you benefit from prefabricated electrical wiring components that snap into place with minimal tools and no guesswork.

At Power Built, we manufacture our own Plug-N-Go modular wiring in-house, so every system is UL-listed and made to spec.

How Modular Wiring Works

Pre-Install Planning

The benefits of modular wiring begin even before the first connector clicks into place. At Power Built, we manufacture components based on your facility’s actual needs—designing custom-length cable whips and modular connectors to match a thoughtfully pre-planned layout. This upfront strategy leads to cleaner, more efficient power distribution with shorter wire runs and balanced circuits, helping reduce energy waste over time.

Simple Installations

Each component in our system is built off-site and delivered ready to go. Keyed and color-coded plugs make connections fast and intuitive, improving safety and helping prevent costly mistakes during installation. Our systems are UL 183 compliant, support up to 20 amps and 600 volts, and are ideal for industrial modular wiring and commercial lighting applications.

Post-Install Flexibility

Facilities change. But with Power Built’s modular wiring systems, you don’t have to start over when they do. Our components can be reconfigured and expanded as your layout evolves, making future updates easier and less disruptive.

The result? A streamlined installation today, and a smarter, more flexible system for tomorrow.

Where Modular Wiring Fits Best

Modular wiring is especially well-suited for:

Warehouses and distribution centers (see how it supports mezzanine lighting)
Manufacturing facilities
Commercial and retail buildings
Data centers
Modular buildings
Spaces with high bay lighting and drop ceilings

Whether you’re lighting a small classroom or a giant industrial space, modular wiring keeps things simple.

How Modular Wiring Compares to Traditional Wiring

How is modular wiring different from traditional wiring?

With traditional wiring, you’re measuring, cutting, stripping, splicing, and hoping everything lines up. Modular wiring simplifies this process with pre-wired components engineered for speed and accuracy.

What are the advantages of modular wiring systems?

Faster installation = lower labor costs
UL-listed components and cleaner layouts = easier inspections and maintenance
Custom-built systems = better fit and future flexibility
Fewer errors = increased safety for installers

Why Choose Power Built?

We design, manufacture, and test our modular wiring systems in-house, so you get faster lead times and a product built to handle the job.

Here’s what sets our prefab wiring systems apart:

Faster lead times than competitors—typically 2–4 weeks for smaller orders and 4–6 weeks for larger ones
UL-listed and hand-tested to meet the highest safety standards
Custom layouts for your space, not someone else’s
No cap on overage coverage—we pay 100%
Built to spec and supports up to 600 volts

We keep things clear and collaborative from day one, because fewer surprises mean better installations.

Bottom Line

Modular wiring takes what is traditionally slow and messy and makes it faster, safer, and easier to manage. With Power Built’s Plug-N-Go system, we’ll help you build a smarter, cleaner layout without the chaos.
