Typical Fault Conduction Pattern

This is a typical conduction pattern, showing a thermal tapering along the coated electrical cable from the electrical connection. The connection, likely the source of the fault, does not appear to be as hot because of the emissivity differences between materials. Phase A is under a load of 67.8A, compared to 70.8A and 70.4A for B and C respectively. There is a 30° C temperature rise between phases. This is definitely a critical fault that requires immediate attention.
