OK, first I searched and nothing on this so time to ask.
I've seen allot of topics on isolation transformers, and no topic about connecting to mains without it will fly.
My question is, with my first year of labs behind me I don't remember it being a requirement of the set up, but that being said, the closest we got to mains power is a variac, that I plugged a transformer into it, then banana plug into the bread board. I'm looking for my lab notes, but i remember the Vpeak at the diode full wave rectifier being in the 40V range.
The transformer was certainly no where near the size of these isolation transformers I've seen, on youtube and very close in size to the transformer we put in the regulated power supply project which was a 120/26 center tap transformer.
At what point (voltage wise I guess) do I need to transition to an isolation transformer?
I don't (yet) have a variac, and plan to for now use the 5V regulated 0-15V power supply built in one of the project labs.
