Re: Safety of Running Coil in Garage



Original poster: "by way of Terry Fritz <teslalist-at-qwest-dot-net>" <dhmccauley-at-spacecatlighting-dot-com>

If you are only running 15kV/60mA you should have no problem whatsoever in
your garage.  Just make sure you ground your secondary from an outside
ground (a 6ft. rod hammered in the ground will work well).  Just don't
connect the RF ground of your secondary to your house ground.  If you had
only a 4kV/20mA coil, this would be fine, but at about 1kW with your
15kV/60mA you really need a dedicated ground.

If I remember correctly, Ed Wingate once told me he first ran his huge
magnifier coil in his basement before he built his outbuilding and that
streamers were going up from the basement
to the first floor!!!
