(I assume you're asking about the simple, DC wands. A surge arrester might avert premature transformer failure. If the transformer failed by "opening"--as they almost always do--it would simply go dead. If it failed by shorting, the surge arrester would allow you to enjoy smooth, surge-free 115VAC coarsing through your writhing body until the rectifier diodes failed. That might happen quickly (although it wouldn't seem so at the time), but diodes aren't designed to act as fuses. If the transformer were high quality, and equipped with over-rating diodes, YOU might go dead! The answer is simple--a fast acting *fuse* on an output lead from the transformer. Finding one as small as ~5mA would be ideal. George Martin uncovered a 31mA fuse in the Mouser catalog. http://mouser.com/products/detail.cfm?MPart=504-AGC-1/32&CustRef=&sou rce=search That's a jolt, but it'd be brief. --Russ -- The silver-list is a moderated forum for discussion of colloidal silver.
