Apr 06, 2010 High-voltage continuous mining machines also have explosion-proof enclosures that do not contain high-voltage switchgear. These enclosures are not designed and tested to withstand high-energy arcing faults. Therefore, to prevent ignition hazards, the final rule requires indicator light circuits to assure that arcing does not occur and injure miners.

Parts 55, 56 and 57, 12025, 12026 and 12027 deal with frame grounding of electrical equipment. In simpler terms, these regulations require the noncurrent carrying metallic parts of equipment being supplied electrical power to be grounded. There are three separate cases to be considered when complying with this regulation.
