Things to Consider When Planning Commercial Electrical Design

Load requirements: We calculate power needs for lighting, HVAC, data systems, and heavy equipment.
Code compliance: Every design follows Connecticut State Building Code and the National Electrical Code (NEC).
Lighting layout: Proper lighting enhances safety, comfort, and energy efficiency.
Scalability: Future expansion is easier when wiring and panels are designed with flexibility in mind.
Technology integration: Smart systems, EV chargers, and automation require foresight in design.
Safety and redundancy: Backup systems and grounding plans protect both people and equipment.

Our design team combines technical expertise with real-world installation experience, ensuring plans that work both on paper and in practice.
