Question
Grounding MSHA metal/Non Metal Mines .
Reference 30 CFR Part K .12069.
Mines do go by NEC (not Officially) with Differences.
Reference MHSA Circular 8835.
Safety Ground /Sub Station grounds.
After reading this over several times. Still confused.
I've talked even to MSHA officals & still????
Anyone have a Contact or know an Expert in this field???
I teach Classes in Electrical & do Mining company's now & then. Want to understand this more clearly.
If you read MSHA Circular 8835 you"ll better understand.
Thanks Yoopersup
