My plant has bought new mcc 480 vac for our substation. They all have RSlogix PLC controller cabinets built in. I noticed that there are two #16 awg tapped on the 800amp buss single phase 480 going to a 5amp fused pull out disconnect that feeds 24v power supply for PLC. Why would they not just come out of a bucket to feed this? This seems very dangerous if someone accidentally cut into these wires because they run parallel for a few feet with other 24 v and 120v PLC. wires?
