Bonding should be, yes. What other kinds of parallel paths could there be, bearing in mind during testing anything not relevant to the testing should be disconnected?
You're saying you disconnect parallel paths apart from bonding while taking a measurement? Good luck with that outside of a 2 up 2 down!
A list of parallel paths is endless. Motor sat on a steel platform for example. Try disconnecting that while measuring Zs.
My point is, parallel paths come and go during the life of the install. The CPC is there to stay so why having a worst case scenario such a bad thing?
For example, man fits motor, motor vibrates, man fits anti vibration feet, parallel path lost, Zs increases. Disconnection time now not achieved.
I'm not saying it's better, just cannot understand some people's resistance to calculate.
