It is to bad that you changed the format for viewing your on-line seminars, because it now requires me to pay money out of my pocket for Real Media Player. Your on-line eduacation is second to none, but why did you change the format for viewing the video. Thanks for your response, Jeff Snyder

Almost all if not all gasoline station equipment manufacturers require and insulated green copper redundant equipment grounding wire in the raceways and wireways that supply their equipment. They also require all conduits to have insulated throat grounding bushings at both ends of each branch circuit raceway.

The British require a redundant grounding conductor in all metal conduits in all occupancies and not just in hospitals like over here. I have opened up enough walls enough times ( once ) to know why they require this.

Also, I have repaired quite a few conduits in factories where the joints broke because of machine vibration or somebody NOT watching what they are doing with a forklift truck.
