They stated it was illegal because anyone.
I used to do msha testing so am familiar
Vfd cables have a great ground internally though We, the installer, are adding all these motor frame jumpers I was told by fellow workers it’s normal here so im thinking it’s just habit Obviously most motors dont come with a way to do this legit so some of it’s wonky.
Msha is mine safety and health administration p means that it meets the additional requirements of the state of pennsylvania bureau of mines 159 means that it was manufactured by the excel cable company, which is now essex 18 means that the cable was certified under 30 cfr, part 18 as flame resistant cable there are more markings on your cable Look up your msha district office and ask an inspector Mine inspectors are tough to mine violators,but good to average joe They don't want to see any shortcuts that can cause an injury or death
Www.msha.gov since both agencies are under the department of labor, i don't think there is any differences and that you aren't allowed to use and apply electricity as your stateing.
For insance msha says that any abandoned wiring must be removed I can't tell you how many industrial plants or even residential areas where you see old dangling wiring hanging out somewhere. That's an msha (mining version of osha) requirement at least for underground and coal mining I had one of my customers get fined for improper panel labeling
All circuits are labeled correctly, they fined them on the spares not being marked No wires hooked up to the breakers at all I guess i have always left these blank so it can be added to when the customer adds something
