*Cord sizes are based on National Electrical Code (1984 Edition) specifications for allowable ampacity for not more than two ther- moset or thermoplastic insulated current-carrying copper conduc- tors in a cord (see Article 400 in NEC for specific information.)

B. Cord Connections

Using proper cords of desired length, make connections to the load bank as follows:

1.Remove front access panel from unit (see Figure 5-1).

2.Strip cord jacket back approximately 5 in (127 mm) and separate conductors; strip 1/4 in (6 mm) of insulation from end of each conductor.

3.Obtain ring terminals of proper capacity and size to fit 1/4 in (6 mm) terminal studs. Install terminals

securely onto stripped ends of conductors for both cords.

4.Insert cords up through strain reliefs in bottom of front access opening. Be sure cords are in cor- rect locations for 120 volt and 240 volt connec- tions (see unit nameplate and Figure 4-1).

IMPORTANT: Do not remove existing leads from ter- minal studs.

5.Remove only the outside nut from each terminal board stud for 120 and 240 volt connections. Re- move top nut from ground terminal stud (see Figure 4-1).

6.Install conductor ring terminals onto studs as in- dicated in Figure 4-1, and secure with nuts re- moved in Step 5.

7.Secure cords by tightening strain relief clamp screws.

8.Reinstall front access panel onto unit.

9.Obtain and install a proper plug that matches the power source receptacle onto remaining end of cords.

10.Place cords in storage area while unit is not in use.
