My uninformed understanding about connection one side of the array to ground was to protect/detect against frame shorts fron putting lethal 600v onto the frame of an array. But then I noticed the connection is made internally with a 1 amp fuse. So u p to 1 A at high voltage can still flow in the ground loop b efore the detector is lost. Isnt there still potentially a lethal possibility? -------------- next part -------------- An HTML attachment was scrubbed...
