around here every service call gets a new NID

Every service call? I can assure you that does NOT happen, particularly if
there ALREADY IS one.

On "every" service call where a NID is NOT present, we are SUPPOSED to install
one. Compliance with this requirement is sometimes poor, particularly if
there is no trouble with the old protector, the customer subscribes to an
inside wire maintenance plan (no charge for any visit) and/or the wind chill
is -40F.
