I understand that man, but there is always that slight chance something could go wrong with something and something bad happens, at least from my experiences and that is with a multitude of things.

Why is it the odd crazy things that we Love so much, yet they can kill us at the same time?

Paul, in this world of risk assessments and hazard identification it is better not to be too blase about what is 'dangerous'. Sometimes the act of getting a tingle from 25V, or it causing a part to smoke or get hot, could lead to a secondary more 'dangerous' reflex reaction if the situation is unexpected. An unexpected tingle, even if it doesn't exceed the theshold of whichever standard you're complying with, is still a hazard. Ciao, Tim

even if it was possible to have an adequate amount of current it has no push(Voltage) to be deadly

In this thread I saw a reader asking about a "Isolation transformer" This is a transformer with two ISOLATED windings The secondary is the SAME as your supply voltage. This is used with mainly service guys doing television sets with "live" chassis. This is to prevent electric shocks handling the chassis. If you should touch ONE lead on the secondary then you should not get an electric shock. I used them working on those old AC/DC sets with their live chassis This is for safety I also used it working on appliances

Man don't they make like some bad *** gloves that are insulated really well for things like that? I have a **** load of non-conductive tools etc, but some gloves like that would really be handy that is if it would be efficient enough to stop anything lethal you know.

The other use of this transformer is how do you connect your MAINS driven instruments. Those days most of the instruments were tube based and needed a mains supply to work.This made such a transformer essential if earth connections were made. Fully solid state oscilloscopes are not that old and spectrum analysers etcetera and these were not all "floating" as the solid state equipment that run for ages on a smallish battery. Those 90 volt batteries were dear and most of the electronics those days worked with an H.T. of 300 plus volts and the display tube ran with 30000 volts plus. AND THEY WERE BULKY AND HEAVY you needed a forklift to handle them. A 50 Kg box was not fun to move around "Those were the days!!!"
