My experience has been that it is normal for C21 power cables to have some difficulty fully seating in the PEM's, even after backing out the set screws more than they already are from the factory. Eventually we get them fully seated and secured, but it's always a bit of a challenge.
I didn't see any specific instructions on this in the Hardware Installation Guide, and I'm wondering if anybody has any surefire methods to get these seated fully without a lot of re-trying, pry bars, sledge hammers, etc.
Thanks,
Phil
