Hi Hi,
We will have isolated three phase bus bars. Fully Mains transformer isolated. (mains input is 240VAC phase to neutral)
We're going to step down the 3 phase mains to the bus bars using a 50Hz 3 phase transformer.
What is the highest VAC level that these bare bus bars can be at and not be a danger to humans touching them?
(ie touching one bus bar, and also touching between two bus bars with each hand)
Also, i presume we have to have the neutral output of the three phase transformer earthed...otherwise the 3 phase output will be floating and could potentially float up to a dangerous level?
