Motor Questions
(OP)
I have a couple of IEEE 841 motor questions as below,
1. Is it necessary to insulate both DE and NDE bearing for Non VFD motor?
2. Motor space heater and RTD terminals are located in the same terminal box with a barriar in between.
Any comments on the above statements? Thanks in advance.

RE: Motor Questions
I am used to seeing power and instrument cables routed separately for larger motors (we don't have rtd's on our small motors). But I didn't see anything about that in IEEE 841.
