3-Phase Commercial Panel & Service Upgrades
Expand electrical service capacity to support high-demand machinery and commercial facilities.
As your commercial enterprise grows, electrical demands grow with it. Adding commercial HVAC units, high-draw manufacturing machinery, heavy refrigeration, or EV chargers requires robust main switchgear. We upgrade commercial service panels from 400A up to 2000A, install dry-type step-down transformers, and balance phase loads.

Frequently Asked Questions
Clear, transparent answers from our master electricians about 3-phase commercial panel & service upgrades in SWFL.
What size panel upgrade does my commercial building need?
We calculate your facility's total connected load (HVAC, lighting, equipment, future expansion factor) according to NEC Article 220 to specify the exact main switchgear size.
How long does a commercial main panel replacement take?
With careful planning and utility shutdown coordination (FPL), main switchgear cutovers are typically executed over a weekend or overnight within 8 to 14 hours.
What is load balancing in 3-phase electrical systems?
Load balancing ensures electrical current is distributed evenly across all three hot legs (A, B, C phase). Imbalanced phases overheat transformers and waste power.
Do commercial panel upgrades require utility transformer upgrades?
If your requested load exceeds FPL's pad-mounted transformer rating, we coordinate transformer upsizing directly with FPL engineers.
Do you install industrial surge protection on commercial switchgear?
Yes, we install high-kA surge suppressors directly at the main service disconnect to protect sensitive commercial automation and server racks.
