The Electrical Professional

Why care for your commercial facility’s electrical distribution system?


Electrical preventive maintenance is cost-effective in many ways, improves equipment efficiency and reduces utility bills. In fact, the Institute of Electrical and Electronics Engineers (IEEE) reports that the failure rate of electrical components is three times higher for systems without preventive maintenance programs.

We offer Electrical Preventive Maintenance Services in all of South Carolina including Charleston, Columbia, Myrtle Beach, Florence, Georgetown, SC and Georgia including Savannah, Brunswick, Beaufort County, GA. 

Equipment loss examples: Commercial Facilities

  • Voltage fluctuation caused two terminal boards in an office building phone system to short out. TOTAL LOSS: $52,500
  • Electrical arcing destroyed three main electrical panels and left an office building without power. Temporary measures are taken to restore power to tenants. TOTAL LOSS: $1,597,389
  • Computers were damaged by a power surge that came through data network lines. Surge suppressors were on electrical and communication lines, but not on the data network line. TOTAL PAID LOSS: $30,800
  • Damage occurs to electrical circuit breakers, store HVAC system, and computer when rain leaked through the roof onto equipment. TOTAL LOSS: $201,547
  • A toilet overflowed above a main electrical distribution panel. Water seeped into the panel and short-circuited the system, causing extensive equipment damages. TOTAL LOSS: $16,500
  • There were surges in the area when guest began complaining of a loss of electricity and heat in their rooms. Repair crews found extensive damage to the main electrical switch-gear and the heat pumps for 40 to 138 rooms. Owners were anxious that repairs be completed before the busy Thanksgiving holiday. TOTAL LOSS: $108,602
  • Loose bus bars shorted out the electrical panel that supplied the HVAC system, setting off sprinklers and cutting off all power. The guest had to rent rooms at another hotel before temporary equipment and generators were installed. TOTAL LOSS: $146,172

Common Problems Include:

  • Overloaded circuits
  • Code Violations
  • Poor Power Quality
    • Harmonics affecting critical systems caused by:
      • Computers
      • Electronic lighting ballast
      • Variable speed drives
    • Improper Grounding due to:
      • New additions and upgrades
      • Non-adherence to the National Electric Code and/or IEEE 1159-1992 standards which are recommended practices for grounding of sensitive electronic equipment
    • Heavy Energy Usage:
      • This generates excessive amounts of heat that cause connections to loosen due to shrinkage and expansion. Loose connections cause arcing that generates extreme heat and high resistance, which is a major safety concern and also results in an inefficient use of power.
      • Budget Constraints
      • Maintenance department has many responsibilities
      • New tenants renovation affecting facility infrastructure

Critical Areas:

  • Incoming service
  • Redundant incoming services and power supplies
  • Main transformer(s) oil & dry
  • Bus Duct
  • Data collection centers

Financial Benefits of Electrical Preventative Maintenance:

  • Predictive budget
  • Minimize or eliminate unexpected outages and untimely repairs
  • Extend the EDS life/lower replacement costs
  • Lower liability risks
  • Greatly reduce electrical fires
  • Computerized documentation for your electrical distribution system
  • Satisfied tenants – higher occupancy

Renovations Can Cause Power Problems:

  • Tenants who perform their own renovations can unknowingly affect the quality of power for the entire facility. These problems affect the day-to-day business or tenants and can be hard to find without proper equipment and expertise

SOLUTION: Regular electrical preventative maintenance will identify and correct all existing problems. It is also highly recommended that a Pre and Post Electrical Inspection be completed to eliminate any problems before they happen.
