You’re renovating or reconfiguring layouts: Wiring updates ensure new rooms and systems have proper power distribution.
You’re experiencing flickering lights or voltage fluctuations: These can indicate loose connections or aging wiring.
You’re upgrading for energy efficiency: Modern wiring and panels support smart systems and efficient lighting.

Things to Consider When Upgrading Commercial Panels or Wiring

Commercial electrical work requires planning, precision, and adherence to strict codes. Before you start, keep these points in mind:

Load capacity: Make sure your panel and circuits can handle current and future electrical demand.
Code compliance: All installations must meet Connecticut State Building Code and National Electrical Code (NEC) standards.
Downtime planning: We coordinate scheduling to minimize disruption to your business operations.
Material quality: High-quality breakers, panels, and wiring improve system life and safety.
Energy efficiency: Properly sized wiring and updated panels reduce wasted energy and lower costs.
Professional installation: Incorrect wiring can cause shorts, inefficiency, or even fire hazards — it’s never worth the risk.

At Cahill Electrical Services, every project is completed by experienced, licensed electricians who understand the demands of commercial power systems.
