When a piece of industrial or commercial machinery powers up in your facility, the last thing you should be thinking about is whether the wiring behind it is safe, code-compliant, or sized correctly for the load. Yet across Scottsdale, Phoenix, Chandler, Gilbert, and the rest of Maricopa County, we see it every week — shop equipment hard-wired to the wrong gauge wire, restaurant hood systems tied into an undersized panel, dental or medical vacuum systems sharing circuits never designed for that load, and manufacturing machinery connected by whoever was available that day rather than whoever was actually qualified. The result is tripped breakers, overheated conductors, failed inspections, and in the worst cases, fires. If you run a business where downtime costs money, or you have heavy-duty equipment in a commercial space that cannot afford a single failure, you need Industrial Machinery Wiring Services done right the first time — and that is exactly what we do at FHR Electric.
What Industrial Machinery Wiring Actually Involves
Industrial machinery wiring is not residential work with bigger wire. It is a discipline that requires a licensed electrician who understands motor starting loads, phase balancing, dedicated circuit requirements, local code, and the real-world demands of equipment that runs hard every day. Whether you are running CNC equipment in a fabrication shop, commercial kitchen appliances in a restaurant, a dental or medical vacuum system in a professional office, or a new piece of heavy equipment in a warehouse — every one of those machines needs its own properly sized, properly protected, dedicated circuit. No sharing. No shortcuts. No guessing on wire gauge.
At FHR Electric, we have handled Industrial Machinery Wiring Services projects ranging from single-machine hookups to full facility buildouts. We pull the permits, we pass the inspections, and we hand you documentation you can keep in your files — because when you eventually sell, lease, or expand, clean permit history matters. If you have ever dealt with a commercial electrical installation that was done without permits, you already know how expensive that mistake becomes.
Industrial Wiring Services We Provide
We work with business owners, general contractors, and facility managers throughout Maricopa County. Here is a closer look at what we handle:
Dedicated Circuits for Heavy Equipment
Every major machine needs its own circuit — sized correctly for the motor load, the startup surge, and any future expansion. We install dedicated circuits for commercial compressors, industrial washers and dryers, CNC machines, laser cutters, welding equipment, and more. We also handle the wire gauge for 50 amp circuits and 40 amp circuits common in commercial environments, and we will never undersize a run just to save material cost.
Restaurant and Bar Equipment Electrical Wiring
Restaurant electrical upgrades are one of our most common commercial calls. A kitchen remodel or equipment addition that seems simple on paper — a new fryer, a walk-in cooler, a hood ventilation control panel — can expose an undersized panel that simply does not have the capacity. We evaluate your existing panel, tell you honestly whether it needs to be upgraded, and execute the work with zero-downtime planning so you are not dark during service hours. We also wire bar equipment including ice machines, glass washers, and refrigeration units, all to code.
Medical and Dental Office Electrical
Operatory circuit requirements are strict for good reason. A dental chair, a sterilizer, a medical vacuum system, and digital imaging equipment all have specific electrical needs — and none of them can share a circuit without risking a tripped breaker mid-procedure. We are experienced medical and dental electricians serving Phoenix, Scottsdale, Chandler, and surrounding areas. We understand operatory circuit requirements, isolated ground circuits, and the importance of a clean, documented installation that satisfies your equipment manufacturers and your malpractice insurer.
Panel Upgrades and Capacity Evaluations
If your panel is not enough capacity for the machines you want to run, the answer is not to add a sub-panel onto a service that is already maxed out. We perform full electrical panel capacity checks and, where needed, complete meter upgrades to bring your service up to what your operation actually demands. We handle everything from cost to upgrade from 100 to 200 amp panel situations to full 400-amp commercial service upgrades. If you are running two EV chargers off one panel alongside commercial equipment, we will design a solution that works now and scales with you.
Laboratory and Specialty Equipment Wiring
Laboratory electrical installation demands precision. Sensitive instruments, environmental controls, fume hoods, and analytical equipment all have specifications that must be matched at the circuit level. We work directly with equipment manufacturers’ wiring diagrams and coordinate with general contractors on tenant improvement projects to make sure every circuit is exactly where it needs to be before equipment arrives on-site.
Gate Operator and Access Control Wiring
Commercial facilities often need gate operator electrical hookups, access control panels, and structured wiring installation for security systems. We handle the full low-voltage and line-voltage side of these installations so you have one electrician coordinating the complete picture — not two subs pointing fingers at each other when something does not work.
Bringing Older Facilities Up to Code
Many commercial spaces in the Valley — especially those in older buildings in Tempe, Mesa, Glendale, and Old Town Scottsdale — are running equipment off wiring that was never designed for modern loads. If you have an old 60 amp panel, aluminum branch circuit wiring, or an electrical system that has not been touched since the building was constructed, we will give you an honest assessment of what needs to change to bring electrical up to code. We also help with closing open permits — if a previous electrician left work unpermitted or walked off a job, we can assess, remediate, and get it closed properly.
“We had three separate electricians tell us our panel was fine. FHR Electric was the first one to actually measure our load and show us in writing that we were running at 94% capacity with zero room for the new equipment. That kind of honesty is what we were looking for.”
Why This Matters More Than You Might Think
Improperly wired machinery is not just an inconvenience. It is a liability. If a machine is wired to an undersized circuit and a fire results, your insurance company will look at the wiring. If it was done without a permit or by an unlicensed contractor, you may find yourself holding a claim denial and a lawsuit at the same time. The cost to wire machinery correctly the first time is a fraction of what you will pay to rewire it after a failed inspection — or to defend yourself after an incident.
For more information on what industrial machinery wiring encompasses as a discipline, including historical standards and code frameworks, see the overview of industrial machinery wiring on Wikipedia. Understanding the depth of this field helps explain why it requires a specialist, not a generalist.
We are also happy to answer questions before you commit to anything.

How We Work — Our Process
We know cost uncertainty and surprise invoices are a real fear, especially on commercial projects that can expand in scope. Here is what working with FHR Electric actually looks like:
- Step 1 — Site Assessment: We come to your facility and look at the existing electrical infrastructure honestly. We measure actual load, identify any code issues, and document what we find. No guessing, no overselling.
- Step 2 — Written Scope and Proposal: You receive a written proposal with a clear scope of work before we touch anything. We do not start work and then tell you the price. You know the number before we schedule.
- Step 3 — Permit Pulling: For any work that requires a permit in Maricopa County, we pull it. We do not ask you to look the other way. Permitted work protects you, your insurance, and your resale or lease value.
- Step 4 — Scheduled Execution: For businesses with uptime requirements, we schedule work to minimize disruption — early mornings, weekends, or phased installation. We plan around your operation, not ours.
- Step 5 — Inspection and Sign-Off: We coordinate the inspection, we are on-site for it, and we handle any corrections. You get the final documentation.
- Step 6 — Walk-Through: Before we consider the job complete, we walk through everything with you or your facility manager and answer every question on the spot.
We Work Across All of Maricopa County
Our team serves Scottsdale, North Scottsdale, Old Town Scottsdale, Phoenix, North Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, Fountain Hills, and the surrounding communities. If you are not sure whether we cover your area, check our full service area page. Chances are we do — and if your project is large enough, distance is rarely a barrier.
If your project also involves new construction wiring for a ground-up facility or a major addition, we handle that too. Many of our commercial clients start with a machine hookup and end up working with us on their full buildout — because once they see how we operate, they do not want to start the vetting process over again with someone new.
Reliability Your Business Can Count On
We are a family-owned electrical company. We are not a franchise that sends whoever is available. When you call FHR Electric, you get licensed electricians who are accountable to the work they put their name on. We understand that for a restaurant owner, a failed inspection means a delayed opening. For a medical office, a wiring error during a procedure room buildout means days of lost revenue and stressed staff. For a fabrication shop, a tripped breaker mid-run means scrapped work and an angry customer. We take that seriously because we would take it seriously if it were our own business.
That is also why we encourage business owners with backup power needs to think about the full picture. Industrial machinery that runs 24/7 is exactly the kind of load that needs to stay online when the grid goes down. Ask us about commercial generator installation and maintenance as part of your overall electrical plan — because the wiring that runs your machines and the backup system that keeps them running during an outage should be designed together, not bolted on separately after the fact.
Ready to Talk About Your Project?
Whether you are planning a full facility buildout, adding a single machine to an existing shop, or trying to figure out why your breaker keeps tripping every time a piece of equipment starts up — we want to hear about it. We will give you a straight answer, a written proposal, and a timeline that respects your operation. No runaround, no surprise invoices, no unlicensed subs.
