9 Recommended Practices for Grounding

Grounding Electrode System. Lightning Protection System. Surge Protection Devices (SPD) (formerly called TVSS) 1. Equipment Grounding Conductors. The IEEE Emerald Book recommends the use of equipment-grounding conductors in all circuits, not relying on a raceway system alone for equipment grounding.

Enclosure door grounding | Automation & Control Engineering …

Mar 13, 2007. #1. Greetings. I have a freestanding 2-door steel electrical enclosure, with components mounted on the doors. Our customer claims the doors need to be grounded (bonded) to the enclosure (I agree so far) but with braided grounding straps, and that stranded wire is unacceptable. My knowledge of NEC tells me that braided is only ...
