electrical maintenance Electrical work is a dangerous job — one that is best left to the experts. One of the easiest ways to make this job less dangerous is with preventative maintenance. Just like a car or home HVAC system, a residential or commercial electrical system needs an annual checkup to ensure the safety and efficiency of the systems. Let’s explore the elements a qualified local electrician should inspect, why these checks are important, and the general recommendations. 

Routine Inspections for Optimal Electrical Health

Electrical maintenance is a vital part of maintaining your system to keep it running smoothly and safely. These inspections help prevent damage and malfunctions of the electrical connections and networks. They are typically conducted in three areas, including:

  • Residential locations
  • Industrial and commercial locations
  • Healthcare and special occupancies. Special occupancies include boatyards/marinas, storage areas, theaters, etc.  

Each area has different electrical requirements and will require specific electrical maintenance. A knowledgeable electrician will understand the intricacies of each and how to troubleshoot any issues. However, there are some general commonalities that you can expect an electrician to take a look at.
