    Default Truck grounding

    I also agree with the older lineman. Many utilities operating standards suggest using system neutral connections, anchor rods, pole grounds and or driven rods. The key is all crew members stay clear of the truck and outriggers while a live operation is being carried out. I might add the higher the voltage the more gradient step and touch potential is involved. Hot trucks are not always going to cause line protection to react! Pole setting or movements better be planned and respected with live line tools, clean ropes or gloves etc. Pole guards and line guards are your buddies. Grounding and truck design for ball grounds chassis continuity etc. Only protect the trucks not people! If I had a buck for every ripped off grounding clamp or twisted temporary ground left behind I could eat ice cream for the rest of my retirement.
    Follow the local rules but know when it comes to grounding the extension of the grounding zone brings more hazards into play not less.

    Derrick trucks should always be grounded whether the line is live or grounded (should be the only options) and to the system neutral if available. The reason for grounding RBDs during dead operations is to bond the boom in case of accidental energization to keep it at the same potential as the worker in the air. When working live it is to help clear the line, but the reality is if you touch the truck at the same time as it is accidentally energized you will be badly hurt if not killed.
