[...] You can touch the 12V battery terminals reasonably safely, but don't try it with the 240V terminals. That voltage is well in excess of the body's 50V limit for being a non-conductor, and the battery can deliver plenty of Amps to be lethal. It isn't the 240V that kill, it's the 21A. Turning fresh meat into smoke and ash can dissipate a great many Watts. -- -- ^^^^^^^^^^ -- Whiskers -- ~~~~~~~~~~
