All, Consider two power supplies, both AC230V to DC12V: PS1 - with basic insulation and one of its output terminals grounded with protective conductor, PS2 - with double or reinforced insulation and floating output. I understand that PS1 is CLASS I equipment, and PS2 is CLASS II equipment. Now consider the 12V powered device connected to one of them. Is that device CLASS III equipment in both cases?
