If you're planning a new commercial space, remodel, or office buildout, you'll hear the term "low voltage" come up — often alongside structured cabling, security cameras, or AV installs. But what exactly is low voltage work, who can legally do it in Oregon, and why does it matter to you as a business owner?
What Is Low Voltage?
Low voltage refers to electrical systems operating at 50 volts or below. Unlike standard "line voltage" electrical work (your outlets, lighting, HVAC circuits), low voltage systems carry data, signal, and control information rather than high-power electricity.
Common low voltage systems in commercial and small business settings:
- Data and telecom cabling (Cat5e, Cat6, Cat6A ethernet)
- Security camera systems (CCTV and IP cameras)
- Access control systems (keycard readers, electronic door strikes)
- Audio/visual systems (TVs, projectors, speakers, matrix systems)
- Intercom and video doorbell systems
- Network equipment rack builds and cable management
Oregon LE Licensing: What It Means
In Oregon, performing low voltage work for compensation requires a Limited Energy (LE) contractor license issued by the Oregon Construction Contractors Board (CCB). There are two tiers:
LE-A (Limited Energy — A) — Covers all low voltage work including fire alarm systems, nurse call, and other specialized life-safety systems. Broader scope, more stringent requirements.
LE-B (Limited Energy — B) — Covers the majority of commercial low voltage work: structured cabling, data networks, security cameras, access control, AV systems, intercoms, and similar installations. This is the license held by Willametro IT Solutions LLC.
Why does this matter to you? Because it means when you hire a licensed LE contractor, you're protected. Licensed contractors carry liability insurance, are bonded, and their work is subject to Oregon CCB oversight. Unlicensed low voltage work is common — and it's a problem when something goes wrong, an inspection catches it, or you try to sell the building.
The Timing Problem: Why Low Voltage Goes In Before Drywall
This is the single biggest mistake we see business owners make: waiting until the buildout is nearly done before calling someone about cabling and cameras.
Low voltage infrastructure — especially data cabling — needs to be run inside walls, above ceilings, and through conduit before those spaces are closed up. Once drywall is on, fishing wire through finished walls is:
- Significantly more expensive (hours of labor vs. minutes)
- More disruptive (patching, repainting)
- Often results in a less clean install
- Sometimes just not possible without major demolition
The right time to bring in your low voltage contractor is during the rough-in phase — after framing is up but before insulation and drywall. At this stage, running cable is fast, clean, and cheap. This is why our partnership with Andrade Construction LLC exists: to coordinate these phases so nothing falls through the cracks on a buildout.
Planning Your Low Voltage Rough-In
If you're doing a buildout or remodel and aren't sure what to plan for, here's a starting checklist to bring to your conversation with a low voltage contractor:
- How many workstations will you have, and where?
- Where will your network equipment (router, switches, NAS) live?
- Do you need security cameras, and if so, where?
- Will you have a conference room or TV display areas?
- Do you want access control on any doors?
- Where will your phone system or intercom live?
- Any outdoor areas that need coverage or connectivity?
You don't need to know all the answers — a good low voltage contractor will walk the space with you and help you think through it. What matters is having that conversation before the walls close.
What Good Cabling Looks Like
Properly installed structured cabling is labeled, documented, terminated in a central patch panel, tested for performance, and routed cleanly. It should support your current needs and leave room to grow — adding a workstation or camera later should mean patching a cable, not hiring someone to run new wire.
If you've ever inherited a space where previous cabling was a jumbled mess of unlabeled cables zip-tied to whatever was handy — you know the difference. Good infrastructure is invisible when it works and easy to troubleshoot when it doesn't.
