Commercial Panel Upgrade & Installation
Kochs Electric handles commercial panel upgrades and installations for businesses that need reliable power distribution, code-compliant wiring, and properly rated electrical infrastructure built to last. Our licensed professionals provide quality electrical services for industrial, commercial, and residential commercial clients across Indiana.
5 Highlights on Commercial Panel Upgrade & Installation
- Full-capacity panel sizing — Kochs Electric calculates your total load demand, fault current, and amperage requirements before specifying any main breaker, distribution panel, or switchboard for your commercial property.
- Code-compliant installation — Every commercial panel upgrade meets NEC and NFPA 70 standards. Permits get pulled, inspections get scheduled, and the AHJ signs off before the job closes.
- Three-phase and single-phase service — Whether your facility runs three-phase equipment or single-phase branch circuits, Kochs Electric installs the right load center, busbar configuration, and feeder-grade conductors for your system.
- Arc flash and short-circuit rated equipment — All panels, breakers, and disconnects are UL listed and short-circuit rated to match your service entrance specifications.
- Labeled, torqued, and tested — Every terminal gets torqued to spec, every conductor gets labeled, and every circuit gets tested with a clamp meter and multimeter before energizing.
Why Choose Our Commercial Panel Upgrade & Installation
Kochs Electric brings licensed master electricians and journeymen to every commercial panel upgrade and installation. No apprentices running jobs unsupervised. No shortcuts on torque specs or grounding.
We pull permits on every project. The AHJ inspects the work. That protects your business from liability and keeps your insurance valid.
Our electricians read single-line diagrams and riser diagrams before touching a panel. We run load calculations, size conductors correctly, and select breakers rated for the actual fault current your service entrance can deliver. That means no overloaded busbars, no undersized feeders, and no tripped breakers six months after installation.
Kochs Electric works with commercial contractors, project managers, and building engineers. We coordinate scheduling, meet code deadlines, and keep the job moving. When a utility company needs a service lateral connected or a meter base inspected, we handle that coordination directly.
We stock EMT, rigid conduit, THHN and THWN conductors, MC cable, and SE cable. Jobs don’t stall waiting on materials.
Every commercial panel upgrade comes with a completed load calculation, labeled circuit directory, and documentation for your records. You get a panel that’s balanced, grounded, bonded, and ready for inspection. Contact us to request a quote and view your options. Our solutions are built to be efficient, reduce costs, and support future growth.
Signs You Need Commercial Panel Upgrade & Installation
1. Breakers trip repeatedly under normal load: A circuit breaker that trips under normal operating conditions signals an overloaded panel or an undersized feeder. If your branch circuits are drawing more amperage than the busbar is rated to distribute, the breakers protect the wiring — but the real fix is a panel upgrade that matches your actual load demand.
2. Your panel uses fuses instead of breakers: Fuse boxes and older fuse-based load centers don’t meet current NEC requirements for most commercial occupancies. If your facility still runs on a fuse box, you’re operating with equipment that can’t be reset, can’t be AFCI or GFCI protected, and won’t pass a commercial inspection.
3. You’re adding equipment or expanding your facility: Installing a generator, VFD, motor control center, LED lighting system, or additional branch circuits on an already loaded panel creates an unbalanced, over-capacity system. A commercial panel upgrade lets Kochs Electric install a properly sized distribution panel or subpanel that handles your expanded load without compromising existing circuits.
4. Your panel shows visible damage, corrosion, or heat marks: Scorched terminals, corroded busbars, and damaged insulation on conductors inside a panel are signs of a fault condition or chronic overload. These aren’t cosmetic issues. They indicate a panel that needs to be de-energized, inspected, and replaced before a fault current event causes a fire or equipment failure.
5. Your facility fails an electrical inspection: If an inspector flags your panel as non-compliant – unlabeled circuits, missing ground bars, improper conductor sizing, or a panel that isn’t accessible or lockable – Kochs Electric can troubleshoot the deficiencies, handle necessary repairs, pull the correct permits, and install a code-compliant replacement that passes re-inspection. Most repairs and replacements are completed in minimal time to get your facility back online.
Our Commercial Panel Upgrade & Installation Process
Step 1 — Site assessment and load calculation. Kochs Electric inspects your existing panel, service entrance, and meter base. We measure voltage, amperage, and current load across all phases. We run a full load calculation to size the replacement panel correctly.
Step 2 — Design and permitting. We produce a single-line diagram and riser diagram for the new installation. Permits get submitted to the AHJ before any work starts. No work begins without approved documentation.
Step 3 — De-energize and disconnect. The utility company coordinates a service disconnect. Kochs Electric de-energizes the existing panel, removes the old equipment, and prepares the mounting surface for the new distribution panel or switchboard.
Step 4 — Install and wire. We mount the new panel, run feeder conductors through conduit, connect the busbar, neutral bar, and ground bar, and terminate each circuit breaker. Every lug gets torqued to manufacturer spec.
Step 5 — Test, label, and commission. We test each branch circuit with a multimeter and clamp meter, balance the load across phases, label every circuit, and energize the panel. The AHJ inspects and approves before the job closes.

FAQs About Commercial Panel Upgrade & Installation
What is a commercial panel upgrade?
A commercial panel upgrade replaces an existing load center, distribution panel, or fuse box with a properly sized, code-compliant panel that matches your facility’s actual load demand. It includes new circuit breakers, busbars, neutral bars, ground bars, and feeder conductors sized to NEC standards.
When does a commercial panel need to be replaced?
Replace a commercial panel when it’s overloaded, physically damaged, fuse-based, failing inspection, or undersized for new equipment. If your facility is expanding or adding three-phase machinery, a panel upgrade is the right move before connecting new circuits.
Why does a commercial panel upgrade require a permit?
The NEC and most local AHJs require permits for any service entrance work, panel replacement, or feeder installation. Permitted work gets inspected, which protects your building, your insurance coverage, and your liability as a property owner or tenant.
How long does a commercial panel installation take?
Most commercial panel upgrades take one to two days depending on panel size, conduit routing, and utility coordination. Larger switchboard replacements or multi-panel distributions may take longer. Kochs Electric gives you a clear schedule before work starts.
Can a commercial panel be upgraded without shutting down the building?
A full panel replacement requires de-energizing the service entrance, which means a temporary power outage. Kochs Electric coordinates with the utility company and your project manager to schedule the disconnect during off-hours or low-impact windows when possible.
Does Kochs Electric handle the permit and inspection process?
Yes. Kochs Electric pulls every permit, submits required diagrams to the AHJ, and schedules all inspections. You don’t manage that process. We do.
How do I know what size panel my commercial building needs?
Panel sizing depends on your total load demand, fault current at the service entrance, number of branch circuits, and any planned equipment additions. Kochs Electric runs a full load calculation before specifying any panel to make sure the equipment is rated correctly for your facility.
