[QUOTE="SPECIAL LOCATION, post: 73791, member: 250"] 30ma is NOT that much current... More like that Little current IMHO. anyway... this is a very complex with many many variables to take into account. Rough guide to typical shock currents can be found in some books by "Brian Scaddan" e.g. 1ma -2ma barley perceptible, no harmful effects 5ma - 10ma Throw off, painful sensation 10ma - 15ma Muscular contraction, cant let go 20ma - 30ma Impaired breathing 50ma & above Ventricular fibrillation and death (patch will know what all the big words mean! :D :P ) Also the NICEIC have some interesting information in their Technical manual.. but it is deep reading & has reference to loads of other documents and tables: heres a taster of the sort of variables and stuff that has to be considered...
