SCCR Engineering Services
Short-Circuit Current Rating (SCCR) Engineering Services
Ensure safety, maintain regulatory compliance, and protect your industrial assets with comprehensive SCCR engineering solutions. We help control panel builders, OEMs, and facility managers calculate, optimize, and document electrical panel ratings to withstand peak fault conditions.
What is SCCR and Why Does It Matter?
-
A Short-Circuit Current Rating (SCCR) represents the maximum level of fault current an electrical control panel or component can safely withstand without causing catastrophic failure, fire, or severe safety hazards.
-
Failure to meet required SCCR levels can result in NEC violations, delayed inspection approvals, severe liability risks, and costly downtime.
Our Core SCCR Services
-
UL 508A Supplement SB Calculations
-
Full evaluation of industrial control panels to determine precise overall panel SCCR using official standard methodologies.
-
SCCR Optimization & Component Upgrades
-
Identifying "weak link" components that drag down your panel's overall rating and delivering cost-effective engineering redesigns to achieve higher SCCRs.
Cost-Effective Solutions
-
Raise panel ratings through smart current-limiting fuse/breaker selection—not unnecessary overhauls.
What Is an Arc Flash and Why Does It Matter?
An arc flash occurs when electrical current deviates from its intended path, traveling through the air and releasing extreme heat and energy. These incidents can cause severe burns, blindness, hearing loss, and even fatalities. Proper arc flash hazard analysis is critical to prevent injuries and ensure workplace safety.
What is the result of an arc flash?
The result of an arc flash is extremely high heat that can cause severe burns, blinding light, and an explosion that can result in hearing damage and potentially fatal injury. Multiple arc flash incidents occur every day in workplaces across the United States.
The safety of your employees and contractor employees from an arc flash should be always at the forefront. This means employees have the proper PPE at all times and follow the rules and regulations of OSHA. There’s an urgency to completing arc flash risk assessments and shock risk assessments: According to changes made for NFPA 70E, these arc flash assessments must be conducted before any person is exposed to electrical hazards. The risk of an arc flash explosion occurring at your facility is not negligible, and the trend of increased power use combined with aging electrical infrastructure across the U.S. heightens the danger. The Electrical Power Research Institute (EPRI) estimates direct and indirect costs to an employer from a fatal electrical accident in the millions of dollars.
What are the requirements for Arc Flash Hazard Analysis & Assessment?
Navigating all of the requirements, conditions, and exceptions that result from these arc flash assessments requires a great familiarity with the new standard. Specifically, NFPA 70E Section 130.4 requires that a shock risk assessment is performed before beginning energized work, and NFPA 70E Section 130.5 requires that an arc flash risk assessment be performed to:
Determine whether an arc flash hazard exists
If a hazard exists, determine:
-
The appropriate safety-related work practices
-
The arc flash boundary
-
The correct PPE to be worn
