Terminals
Standard line and ground terminals supplied with DynaVar arresters will accommodate conductor sizes from .25-inch to .81-inch diameter. The terminals are of hot-dip galvanized ferrous material, compatible with either aluminum or copper. Line end terminals are available either as a single eye-bolt (Cat. No. suffix –3001) as shown in Fig. 1 (Example 300703-3001) or as a 2-hole NEMA pad with single eye-bolt (Cat. No. suffix – 3003) as shown in Fig. 2 (Example: 300703-3003). Ground end terminals are single eye-bolt, automatically included with either suffix. Terminals are shipped in a separate bag. Maximum recommended tightening torque to be applied to the line end stud when installing the terminals and the lead is 20 ft-lbs.

Base Mounting Information
All DynaVar PVIA intermediate arresters for outdoor use should be mounted in an upright position, above the level of ground splash, drifting snow, flood water, etc. Units may be inverted if not exposed to the weather. For outdoor underhung applications, please contact the Ohio Brass Co. The end castings are furnished with three holes at 120 degrees on 8.75-inch diameter bolt circle. These mounting holes are .56- inch diameter to accommodate .5-inch bolts. (Mounting bolts and washers are not furnished with the arrester.)
