Modernize Your Electrical Systems Without Full Replacement

System upgrades and retrofits for aging industrial electrical infrastructure in Johnston, Iowa.

When your facility in Johnston is running on outdated panels, undersized feeders, or equipment that no longer meets code, a full system replacement is not always necessary. Jenson Electric, LLC. provides targeted upgrades and retrofits that bring your electrical infrastructure up to current standards while keeping your operation online. Retrofits address capacity limits, obsolete components, and code violations without tearing out systems that still function.

Upgrades include panel replacements, circuit additions, transformer installations, and feeder upsizing to support new equipment or increased loads. Retrofit work focuses on swapping out aging breakers, relays, and disconnects while reusing existing conduit and wire where safe and compliant. Code compliance improvements address grounding, labeling, working clearances, and arc flash hazards identified during inspections. Work is scheduled in phases to minimize downtime and coordinated with your production or operational calendar.

If your facility in Johnston needs more capacity, updated components, or code corrections, get in touch to review your current system and discuss what can be upgraded in place.

How Upgrades and Retrofits Are Planned and Installed

Your project starts with a walkthrough and review of your existing electrical distribution, panel condition, and load calculations to identify what needs replacement and what can stay. In Johnston, Jenson Electric, LLC. creates a scope that prioritizes safety, capacity, and compliance without unnecessary demolition. Panels are replaced during scheduled downtime, and circuits are transferred in stages to keep critical equipment running.

After the upgrade, you will notice clearer labeling, improved breaker coordination, and fewer nuisance trips during startup or peak load. Retrofitted systems respond faster to faults and provide better protection for motors and control equipment.

Capacity upgrades may include new transformers, service entrance upgrades, or subpanel additions depending on your facility layout and utility service. Code compliance work addresses arc flash labeling, working space clearances, and grounding electrode connections that may have been missed in older installations. Jenson Electric, LLC. coordinates utility shutdowns and inspection scheduling as part of the upgrade process.

It helps to know what to expect before scheduling.

These are common questions from facility managers and business owners in Johnston who are planning system upgrades or evaluating whether a retrofit makes sense for their operation.

What is the difference between an upgrade and a retrofit?
An upgrade increases system capacity or replaces entire sections of electrical infrastructure. A retrofit updates specific components within an existing system, such as breakers, relays, or disconnects, while reusing panels and conduit that are still serviceable.
How do you minimize downtime during an upgrade?
Work is scheduled during off-hours or planned shutdowns, and circuits are transferred in stages to keep critical loads energized. Temporary power may be used in some cases to avoid full facility outages.
When does a system need a capacity upgrade?
Capacity upgrades are needed when you add new equipment, expand production areas, or experience frequent breaker trips due to overloaded circuits. Load calculations determine whether your existing service and panels can handle the additional demand.
What code compliance issues show up during upgrades?
Common issues include missing arc flash labels, insufficient working clearances around panels, improper grounding, and outdated breaker types. Jenson Electric, LLC. addresses these as part of the upgrade to bring your system into compliance with current codes.
Can you retrofit a panel that is no longer manufactured?
In some cases, yes, if compatible breakers and components are available. If parts are discontinued or unsafe, panel replacement is recommended to ensure long-term reliability and code compliance in your Johnston facility.
