7. What size wires can be attached using the standard wire clamp?

Hubbell arrester terminals are clamp type and suitable for industry standard wire sizes from No. 6 AWG solid to No. 2 AWG stranded, which are metric sizes 16mm2 to 35 mm2.

8. Are there any restrictions on how to attach the ground lead connection?

The ground lead disconnector (GLD) needs to be able to completely separate from the arrester in the remote event of failure. Disconnecting allows the feeder to be re-energized and provides visual indication of the failure location.

TIEEE C62.11 and IEC 60099-4 require minimum information be included on the nameplate of each surge arrester. An example nameplate is shown below. Additional nameplates are used based on requirements and requests.
