AC is roughly the same. The value I have is 23 Vrms @ 50mA. I'm told that AC shock survival is lower because 60 Hz interferes with the natural beating of the heart ( roughly 60 Hz ). My numbers come from a safety course I took last year. WHMIS++ for Canadians who want to know. I don't have a concrete source at hand, but if flamed sufficiently will look one up. These numbers seem small to me, but I suspect a bathtub is involved. |~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~|~~~~~~~~~~~~~~~~~~~~~~~~~| | Geoff LeBoldus | Queen's University | | BITNET: LEBOLDUG@QUCDN.QueensU.CA | Kingston, Ontario | | "requisite generic quote" | Canada | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
