Custom Control Panel Shop

Scope of Work Cummings Electrical designed and fabricated a Kirk Key Interlock Control Panel supporting a mission-critical power system for a confidential client at a secure facility. The project integrated mechanical interlocking, control circuitry, and safety logic to ensure proper power sequencing and prevent unsafe switching conditions during maintenance and operational transitions. The scope included full UL 508A compliance, documentation, internal QA review, and final validation prior to shipment.

Challenges & Solutions The primary challenge was the precision required between mechanical interlocks and electrical control logic — minor alignment errors could cause improper sequencing or system lockout. Cummings maintained structured communication with site engineers to ensure the panel matched field installation constraints, and assigned a single dedicated technician to the full build to eliminate workmanship variability. Early material tracking and proactive vendor engagement kept the schedule intact despite supply chain constraints. Internal inspections and functional verification were conducted in strict alignment with UL 508A requirements prior to release.

Results Delivered on time and within budget, the panel met the client's critical operational deadline and demonstrated Cummings Electrical's capability in high-reliability, safety-focused control systems. The quality of execution led to repeat business and formal client recognition, strengthening long-term partnerships in the mission-critical market.

Scope of Work Cummings Electrical designed and manufactured a custom Power Pedestal for the City of Grapevine to support safe, reliable electrical distribution for public events throughout the downtown district. The scope included full concept development, electrical design, fabrication, and UL 508A-compliant validation. The final unit featured a 240VAC, three-phase, 200A service with branch distribution, multiple receptacle configurations, and internal grounding — all housed in a weather-resistant enclosure with a clean, public-facing aesthetic appropriate for a high-visibility municipal setting.

Challenges & Solutions The pedestal had to balance electrical safety and code compliance with outdoor durability and accessibility for a wide range of end users. Close coordination with city engineers defined load requirements, receptacle configurations, and placement constraints within existing downtown infrastructure. Early procurement tracking mitigated schedule risk from long-lead components, and a single lead technician completed the build start to finish — ensuring consistency in wiring, labeling, and torque standards. Quality reviews at multiple assembly stages confirmed the system met both regulatory and customer acceptance criteria.

Results Delivered on time and within budget, the pedestal gave Grapevine a purpose-built solution that improved safety, reliability, and power flexibility for downtown events. Strong municipal stakeholder feedback and follow-on interest for additional units further demonstrated Cummings Electrical's ability to deliver infrastructure solutions that combine technical rigor with real-world usability.

Scope of Work Cummings Electrical designed and manufactured a custom PLC Control Panel (PLC1) for a mission-critical industrial application, requiring high-density control architecture with distributed field I/O, power management, and networked control systems in a compact, serviceable enclosure. The scope included full panel layout, electrical integration, wiring, labeling, and UL 508A-compliant validation — incorporating multi-tier DIN rail assemblies, segmented terminal blocks, and structured I/O grouping to support field termination, troubleshooting, and long-term maintainability.

Challenges & Solutions The primary challenge was managing high-point-count I/O and dense wiring while maintaining service clearances, labeling accuracy, and separation between power and control circuits. Cummings implemented a structured internal review process covering layout validation, wire numbering verification, and terminal mapping audits prior to build. Standardized wiring practices and torque specifications were enforced throughout fabrication.

A customer-attended Factory Acceptance Test (FAT) was conducted onsite, including I/O point validation, power-up sequencing, and control logic checks. The panel passed without corrective actions — demonstrating both design integrity and build quality.

Results Delivered on schedule and in full compliance with customer and UL requirements, enabling immediate field installation. The successful FAT earned strong client confidence, formal recognition, and follow-on project discussions — reinforcing Cummings Electrical's reputation for delivering technically rigorous control systems that perform as designed the first time.
