Hi,
I'm struggling with a separation of circuits issue. The Standard I'm using is UL60065. Many other Standards allow wires of different voltages to be in contact with each other as long as they're both rated for the higher voltage. UL60065 doesn't have a separation of circuits section and I cannot find anything that allows wires of different voltages to touch each other. Paragraph 8.5 allows for short circuiting. Section 13 is creepage and clearances but I cannot find a requirement that will allow a low voltage wire to touch a line voltage wire even if the low voltage wire is rated for the higher voltage. I noticed 60950 and 61010 don't seem to have this allowance either. For 60065, can anyone point me in the right direction? If 60065, 60950 and 61010 don't allow it, can anyone explain why these standards don't but others do?? For reference, some that allow it - UL508A (Control Panels), UL73 (Motor Operated Appliances), UL499 (Heating Appliances). Any feedback is appreciated.
