Thanks Karl, though I've been successful with the fence method, but there is alway the one time. Working as a commercial electrician after many safety meeting had it drilled into my head to not stand in front of 480 volt services when first turned on. They occasionally explode. So stand to the side or best option is have the apprentice do it. I thank you for the link as I prefer to keep the functioning parts of my body out of the danger zone.
