• SPLIT PHASE FUNCTION: This setting enables and disables the function.
• SPLIT PHASE SOURCE: This setting specifies a signal source used to provide current from the split phase CT to the
split phase protection.
• SPLIT PHASE LOAD SOURCE: This setting specifies a signal source used to provide current from the load CT to the
