The clarifications. presented in this report address actual test. configurations and other analysis a..d experience which Limitorque uses to support environmental qualification of its actuators.

Limitorque and the Group members agreed that' case-by-case considerations, other qualificattu test data, and utility specific. analysis are used in combination with the referenced Limitorque reports to support actuator environmental qualification.

Therefore, clarifications contained in this document do not fully reflect the 'tinal qualification evaluat ans which apply to installed Limitorque actuators.

0063948 LIMITORQUE Page 23 It,y$s,noted that the Harathon 300 series blocAs?.were de-f,

f rated by UL from 600V to 300V.

This resulted in LimitorquC3, decision to use every other terminal point, e.ge, alternate vs.

adjacent, for power viring in subsequent Limitorque tests.

Both et Limitorque and the' discussion. group members present agreed that the use of. alternate vs.

adjacent viring does notiaffect the performance or level of qualification provided for the Harathon 300 blocks based on the B0119 testing.

Finally, Limitorque stated that the use of environmentally qualified splites in lieu of terminal blocks, in both power and control circuits, was an acceptable configuration.
