Typically problems in signal wires don’t burn the DMX-512 equipment. Signal wires short circuit, signal wires cut, mixed wiring and wrong cable impedance just lead to not working. Overvoltage can kill the line transceiver chips if not very well protected (protection level varies between equipment). Lack of grounding in devices, cut ground shield on data cable, ground loops and ESD can cause overvoltages that can potentially damage the components typically near the input and output ports.

Another good article from ETC which calculates that neutral overcurrent can actually be as high as 1.7 times the the hot circuit current. https://support.etcconnect.com/ETC/Power_Controls/General/Common_Neutral_Wiring_in_ETC_Systems
