Grounding and Earth Resistance Testing


Confusing standards and conflicting opinions have plagued the field of grounding. One of the most important, but least understood considerations in designing and maintaining electrical systems is the grounding of all components. Low resistance earth grounding is essential for safety and protection of sensitive electronic equipment. It is the basis for any facility’s power quality assurance program.

Effective earth grounding is essential for grounded AC and DC electrical equipment and distribution systems.

Effective grounding provides the level of safety required to protect personnel and equipment from shock and fire hazard. The understanding and evaluation of a facility ground system should be part of any power quality assurance program.

Some of the basic requirements of an effective ground system include:

  • Limits voltage in a electrical distribution system to definite fixed values
  • Limits voltage to within insulation ratings Provides a more stable system with a minimum of transient over voltage and electrical noise
  • Provides a path to ground in fault conditions for quick isolation of equipment with operation of ground fault protection
  • Provides grounding of all conductive enclosures that may be touched by personnel, thereby eliminating shock hazards
  • Reduces static electricity that may be generated within facilities
  • Provides protection from large electrical disturbances (such as lightning) by creating a low resistive path to earth


NFPA 70E 2021

Is your site NFPA 2021 compliant? Is your staff "qualified" or "unqualified" to work on electrical equipment?

Burlington Electrical Testing conducts onsite Arc Flash Hazard Awareness training which provides an understanding of the federal laws (OSHA), potential dangers, as well as the accepted safety practices when personnel are to be exposed to electrical hazards.

This includes defining an arc flash and its effects on the human body, complying with Arc Flash labeling, and the selection and use of Personal Protective Equipment (PPE).

The Arc Flash Hazard Awareness class is to be part of your overall electrical safety program; therefore, your staff will require a working knowledge of the electrical equipment at their facility, along with the tools, test equipment and available PPE.

The one day class is presented by an instructor certified by NFPA, and the NJACT / NECA to instruct Electrical Safety Related Work Practices based on NFPA70E 2018. Curriculum follows the accompanying Electrical Safety-Related Work Practices text modules and will focus on:

1. Electrical Safety Culture
2. Electrical Hazard Awareness
3. OSHA and NFPA 70E concepts
4. Electrical Safety Program
5. The Control of Hazardous Energy
6. Arc Flash Hazard Analysis
7. Personal Protective Equipment
8. Existing Electrical Equipment
