Client: Leading Electrical Contractor
Industry: Commercial Construction
Project Location: Large Multi-Occupancy Commercial Facility
Challenge: Seeking Expert Guidance for a Complex Electrical Installation
A major electrical contractor was responsible for the electrical installation of a multi-tenant commercial facility. While the contractor had a traditional installation planned, they reached out to NJ Sullivan for expert consultation on the most efficient way to manage the building’s 1600A electrical service entrance and distribution.
Key project requirements included:
- Efficiently landing and terminating the incoming electrical service.
- Providing high-amperage protection using a safety disconnect switch (such as a Bolt Switch or Pringle Switch).
- Enhancing arc flash and ground fault protection for increased safety.
- Ensuring reliable distribution of energy across the electrical intake room.
The contractor was seeking best-practice recommendations and NJ Sullivan’s engineers proposed an integrated, modular custom solution to significantly reduce installation time, cost, and risk.
Solution: NJ Sullivan’s Applications Team Identifies a Smarter Approach
After reviewing the electrical design, NJ Sullivan’s experienced applications team proposed a custom-engineered solution that streamlined the entire installation process.
Our Recommendations:
- Header Box with Hard-Bussed 1600A Service:
- Eliminated the need for complex field wiring by integrating a hard-bussed connection from the service intake to the safety disconnect switch (Bolt Switch or Pringle Switch, depending on project needs).
- Provided a compact, efficient, and safe termination point for incoming power.
- 50 ft of Bussed Trough for Safe & Efficient Energy Distribution:
- Enabled seamless power distribution throughout the electrical intake room.
- Eliminated the need for cutting, pulling, and terminating wires, dramatically reducing installation time and labor costs.
- Scalable Design with CT Cabinet Integration:
- The system allowed for multiple CT cabinets to be connected directly to the bussed trough, ensuring adequate capacity for present and future energy metering needs.
Results: Time, Cost, and Risk Reduction for the Contractor
By leveraging NJ Sullivan’s application expertise, the contractor optimized their installation approach and gained significant benefits:
- Time Savings:
- The pre-engineered modular system eliminated extensive field wiring, cutting installation time by an estimated 40%.
- Cost Reduction:
- By reducing labor requirements, material waste, and installation complexity, the project saw significant cost savings.
- Enhanced Safety & Reliability:
- The use of arc flash and ground fault protection, along with a fully integrated hard-bussed system, reduced electrical hazards and improved long-term reliability.
- Higher Installation Quality:
- Eliminating excessive field terminations ensured a cleaner, more precise installation, reducing the risk of human error.
Conclusion
This project underscores the value of expert consultation in electrical design. NJ Sullivan’s Applications team helped the contractor identify improvements to their original design, leading to a safer, more cost-effective, and time-saving installation process.
By engaging early in the project lifecycle, NJ Sullivan continues to provide smart, practical solutions that deliver real value to electrical contractors.
