Motor Lead Termination

Motor leads are normally terminated using a Connector or Terminal Box (see

Figure 2-7) or Flying Leads. When no termination is provided and the motor

leads just exit the motor housing, this is called “Flying Leads”. For flying

leads, refer to the motor packing list to determine the lead configuration.
