Welcome back to This Month in Electrical Safety, where we cut through the noise and focus on what actually matters for manufacturers, integrators, and facility owners across the United States.

April 2026 brought a fresh wave of developments; not recycled talking points, but real shifts in how compliance is being interpreted, enforced, and expected in the field.

If there’s one theme tying everything together this month, it’s this: expectations are rising faster than most companies realize.

Let’s get into it.

AHJs Are Getting More Selective About Who They Trust

One of the most noticeable trends across the U.S. in early 2026 is a growing divide in how Authorities Having Jurisdiction (AHJs) evaluate third-party reports.

It’s no longer enough to show up with a label and a generic report.

AHJs are starting to scrutinize:

• The credentials of the evaluation body
• The depth of testing performed
• Whether the report actually reflects the equipment in front of them

We’ve seen multiple jurisdictions push back on incomplete or template-d evaluations, asking for clarification, rework, or in some cases, completely new assessments.

This is a shift from “check the box” to “prove it’s safe.”

For companies relying on third-party approvals, this directly impacts timelines, project costs, and overall electrical safety compliance.

Shortcuts in Control Panel Builds Are Getting Flagged Faster

Another emerging issue in 2026 is the increasing number of control panels being flagged during inspections for seemingly minor (but critical), deficiencies.

We’re talking about things like:

• Improper wire bending radius and routing
• Missing or inconsistent conductor identification
• Overlooked SCCR (Short-Circuit Current Rating) markings
• Inadequate spacing between components

These are not new requirements. What’s new is how quickly they’re being caught.

Inspectors and third-party evaluators are zeroing in on workmanship and construction details that used to slide through unnoticed. In high-density automation environments, even small oversights are being treated as indicators of larger safety risks.

The takeaway? Build quality is now directly tied to your ability to demonstrate electrical safety compliance.

Used and Refurbished Equipment Is Under a Microscope

Across multiple industries, especially semiconductor, packaging, and general manufacturing, used equipment continues to flood the market. And with it comes a growing compliance challenge.

In April, we saw a spike in projects involving:

• Imported used machinery with no traceable certification
• Refurbished equipment missing original safety components
• Systems modified in ways that void prior approvals

AHJs are increasingly treating this equipment as new to the facility, meaning it must meet current code expectations and not the standards it was originally built to.

This is catching a lot of companies off guard.

Buying used equipment may save capital upfront, but without proper evaluation, it can stall installation entirely.

Disconnecting Means Are Getting More Attention Than Ever

It might sound basic, but disconnecting means have become a surprisingly common failure point in 2026.

We’re seeing issues like:

• Disconnects not within line of sight
• Incorrect labeling or missing identification
• Inadequate lockout capability
• Improper selection for the application

Why the sudden focus?

Because disconnects are a front-line safety control. When something goes wrong, they’re the first line of defense for personnel working on or around the equipment.

AHJs and inspectors are increasingly treating disconnect compliance as non-negotiable. If it’s wrong, the entire system is often flagged.

For facilities, this reinforces a broader point: small oversights can have outsized impacts on electrical safety compliance.

Multi-Voltage Systems Are Creating New Confusion in the Field

Modern equipment is getting more complex, and one area where that complexity is showing up is in multi-voltage systems.

We’re seeing more machines that combine:

• Low-voltage control circuits
• Higher-voltage power distribution
• Integrated power supplies and converters

The issue isn’t the technology alone but it’s how it’s being documented and labeled.

In April, several evaluations revealed:

• Inconsistent voltage labeling across components
• Lack of clear separation between voltage classes
• Confusion during troubleshooting and maintenance

From a safety standpoint, this creates real risk. Personnel need to clearly understand what they’re working on at all times.

Clear labeling, documentation, and design intent are becoming essential elements of electrical safety compliance, especially as systems become more integrated.

Temporary Installations Are No Longer Being Treated as “Temporary”

Another interesting development this year is how temporary equipment setups are being viewed.

Historically, temporary installations such as: pilot lines, R&D setups, short-term production runs, were often given a bit more flexibility. That’s changing.

AHJs are increasingly applying the same standards to temporary setups as they would to permanent installations, especially when:

• Equipment is energized for extended periods
• Personnel are regularly interacting with the system
• The setup resembles a production environment

In other words, “temporary” is no longer a free pass.

This shift is forcing companies to rethink how they approach early-stage deployments. Even short-term systems need to meet full electrical safety compliance expectations if they’re going to operate safely and pass inspection.

Documentation Gaps Are Slowing Down Projects

While documentation has always been important, 2026 is making one thing very clear: incomplete documentation is now a project risk.

We’re seeing delays tied to:

• Missing wiring diagrams
• Outdated schematics that don’t match the build
• Lack of component specifications
• Incomplete evaluation records

In some cases, the equipment itself is perfectly safe, but without the right documentation, it can’t be approved.

This is especially common with fast-moving projects where changes happen on the fly but aren’t properly recorded.

What This Means for U.S. Facilities Right Now

April 2026 didn’t introduce entirely new codes or standards, but it did raise the bar on how existing ones are being enforced.

Across the board, we’re seeing:

• More detailed inspections
• Higher expectations for workmanship
• Increased scrutiny on documentation
• Less tolerance for ambiguity

The common thread is accountability. It’s not enough to intend to be compliant, you have to prove it, clearly and consistently.

Facilities that are adapting to this reality are moving faster through approvals and avoiding costly rework. Those that aren’t are feeling the friction.

This Concludes Another Month in Electrical Safety.

This month reinforced a simple but important idea: electrical safety in the United States is becoming more precise, more documented, and more unforgiving of shortcuts.

For companies that take a proactive approach, that’s actually good news. Clear expectations mean fewer surprises and safer operations.

At Lewis Bass International Engineering Services, we’re seeing firsthand how these trends are playing out across industries. Whether it’s evaluating unlisted equipment, helping navigate AHJ expectations, or tightening up system documentation, the goal remains the same: make compliance straightforward, efficient, and reliable.

We’ll be back next month with more real-world insights.

Until next month—stay proactive, stay compliant, and most importantly: stay grounded.
