Commercial Electrical Disconnect Installation & Repair

Electrical disconnect switches play a critical role in commercial electrical systems by allowing power to be safely shut off during maintenance, repairs, or emergencies. These devices help protect equipment, technicians, and building occupants by isolating electrical circuits when work needs to be performed.



At RL Roberts Electric, we provide professional electrical disconnect installation, repair, and replacement services for commercial and industrial properties. Our licensed electricians ensure disconnect switches are installed properly, meet current electrical code requirements, and provide safe power isolation for your building’s electrical equipment.

What Is an Electrical Disconnect?

An electrical disconnect is a safety device that allows power to be manually cut off from a specific piece of equipment or section of the electrical system. Disconnect switches are commonly installed near equipment so technicians can safely service or repair machinery without risk of electrical shock.


Disconnects are required by electrical codes for many types of commercial equipment, including:


  • HVAC systems
  • Commercial refrigeration units
  • Industrial machinery
  • Electrical panels and subpanels
  • Motors and pumps
  • Commercial kitchen equipment


Properly installed disconnects make maintenance safer and help prevent electrical accidents.
