Standard 120/240V service
Lower installation cost
Sufficient for most office and retail loads

3-Phase Service

Required for businesses with heavy equipment, large HVAC systems, commercial kitchens, manufacturing, or any facility with motors over 5 HP.

208V or 480V 3-phase service
More efficient for motor-driven equipment

Frequently Asked Questions

Common signs include frequently tripping breakers, inability to add new equipment or circuits, a panel that's over 25 years old, or a business expansion requiring more power. We perform a load analysis to determine your current usage versus panel capacity and recommend the right upgrade.

3-phase power delivers electricity in three alternating currents, providing more consistent power for heavy equipment. Restaurants with commercial kitchen equipment, medical offices with imaging machines, manufacturing with motors, and any business adding HVAC equipment over 5 tons typically benefit from 3-phase service.

A standard commercial panel replacement typically takes 1–2 days. A full service entrance upgrade with utility coordination can take 3–5 days including the utility reconnection. We schedule work to minimize impact on your business operations.

Yes. Service entrance upgrades require coordination with TECO, Duke Energy, or Withlacoochee River Electric Cooperative for the utility side of the connection. We manage this coordination, including scheduling the utility disconnect and reconnect, so you don't have to navigate that process yourself.

Service size depends on your total electrical load, equipment, HVAC, lighting, and future expansion plans. Most small commercial buildings need 200A single-phase or 3-phase service. Larger buildings, restaurants, and manufacturing facilities often require 400A–2000A service. We perform a load calculation to determine the right size.

Yes. Adding a sub-panel is often the most cost-effective way to add capacity for a specific area without replacing the main panel. We install sub-panels fed from the main panel to serve additions, new equipment areas, or tenant spaces.

Yes. All commercial electrical panel work in Florida requires a permit and inspection. We handle the permit application, coordinate the required inspections, and obtain final sign-off from the local building department.
