29 Under Family Types, click New.<br />

30 For Name, enter 1/6 HP - 115 V - 1 Ph.<br />

31 Click OK.<br />

32 Specify the following values for the shared parameters in the Family Types dialog:<br />

■ Voltage = 115<br />

■ Phase = 1<br />

■ Number of Poles = 1<br />

■ Motor FLA = 4.4<br />

■ Motor HP = 1/6<br />

The value for Power is calculated from the parameter values specified.<br />

33 Using the same method, create additional Family Types with the following parameter values:<br />

Name<br />

1 HP - 208 V - 1 Ph<br />

2 HP - 208 V - 3 Ph<br />

3 HP - 460 V - 3 Ph<br />
