Service Upgrade
Commercial Electrical Service Upgrades by Nexklima Inc.
Adding heavy HVAC machinery, expanding production lines, or installing EV charging banks often exceeds a facility’s existing electrical service capacity. Nexklima Inc. engineers and executes commercial electrical service upgrades, expanding main electrical panels, transformers, and switchgear to safely support increased electrical loads.
Avoid blown fuses, voltage drops, and breaker trips by ensuring your building power infrastructure keeps pace with operational growth.
Complete Service Upgrade Portfolio
1. 3-Phase Main Panel & Distribution Upgrades
Transitioning legacy or under-capacity panels to high-amperage 3-phase service engineered for heavy commercial loads.
- Service panel expansions (Up to 400A, 800A, 1200A, 2000A+)
- 120/208V and 277/480V 3-phase panelboards and main breaker retrofits
- Load balancing across phases to eliminate overheating and voltage imbalances
2. Transformer & Switchgear Modernization
Upgrading central primary distribution equipment to handle heavy equipment inrush currents and continuous loads.
- Dry-type step-down transformer installations and sizing
- Commercial main switchgear replacement and section additions
- Thermal imaging inspections and switchgear busbar torque checks
3. Utility Coordination & Permitting Management
We manage the entire utility upgrade process to ensure minimal facility downtime and zero regulatory compliance friction.
- Electrical load calculation submittals to local utility companies
- Service drop, meter socket, and underground service entrance upgrades
- Scheduled outage coordination during off-peak or weekend hours
When to Schedule a Commercial Service Upgrade
- Expanding Mechanical Infrastructure: Installing new heavy chillers, boilers, or large RTUs.
- Adding Fleet EV Chargers: Introducing Level 2 or DC Fast charging stations.
- Frequent Breaker Trips: Main breakers tripping or panels running abnormally hot.
- Facility Expansion: Adding floor area, tenant units, or high-draw industrial machinery.
Frequently Asked Questions
How do I know if my facility needs a 3-phase electrical service upgrade?
If you are adding equipment with high electrical demand—such as commercial chillers, EV chargers, or industrial tools—and your main breakers are frequently tripping or running near full capacity, an upgrade is necessary.
Will a service upgrade require shutting off building power?
Yes, a brief planned power outage is required for final tie-ins. Nexklima Inc. coordinates scheduled utility shutdowns during off-hours or weekends to minimize business disruption.
