Ok 91D's your time to shine. Because I'm being told I don't know what I'm talking about after 8 years of setting generators up in the army and having a bachelor's degree in Electronic Engineering Technology. Does a trailer mounted 20Kw-2000Kw generator powering a seperate trailer mounted high amperage equipment require a grounding rod? I'm getting attitude when I asked "where is the grounding rod?" Does a trailer mounted 20Kw-2000Kw generator require a grounding rod?

Call me crazy.....but don't ALL generators used by the Army have grounding rods that need to be used? If a small 3-5K generator needs one then logic would SURELY dictate those trailer mounted ones need a grounding rod

Unless someone wants to what what 200A feels like going through their heart, it’s not required.

All jokes aside show them TC 6-02.6. Everything is in there. All power generation equipment needs to be properly grounded. It is against so many national and army regulations to not have a ground. Here’s an OSHA document encompassing grounding requirements for portable gen sets. https://www.osha.gov/OshDoc/data_Hurricane_Facts/grounding_port_generator.pdf
