1926.963(d)(3) Isolated Ground Return

OSHA 1926 Construction > V Electric Power Transmission and Distribution > 1926.963 Testing and Test Facilities > 1926.963(d) Grounding Practices > 1926.963(d)(3) Isolated Ground Return
JUMP TO FULL CODE CHAPTER
In highpower testing, the employer shall provide an isolated ground-return conductor system designed to prevent the intentional passage of current, with its attendant voltage rise, from occurring in the ground grid or in the earth. However, the employer need not provide an isolated ground-return conductor if the employer can demonstrate that both of the following conditions exist:

1926.963(d)(3)(i)

The employer cannot provide an isolated ground-return conductor due to the distance of the test site from the electric energy source, and

1926.963(d)(3)(ii)

The employer protects employees from any hazardous step and touch potentials that may develop during the test.

Note to paragraph (d)(3)(ii): See Appendix C to this subpart for information on measures that employers can take to protect employees from hazardous step and touch potentials.
