Here is the scenerio. We will be installing a feeder run as follows:
MDP in basement to pullbox in basement in 2-1/2" EMT.
At pullbox (metal), we will transition to PVC, which will run approximately 100' under the builidings concrete slab. No basement under this part.
At the end of the PVC run, we need to transition to an RMC 90d elbow up a wall (through a cavity) (we are installing this run directly below a 4" concrete slab)
The RMC 90 will transition back into EMT for approximetely 15' up the wall to another pull box.
We will be pulling a ground with the feeders.
Here are the questions, 1)do I need a secondary bond to the RMC 90? Or are we good with the grounding because of the EMT? And 2) if we need a secondary bond to the RMC, anyone know of a fitting that works?
If this isn't clear, let me know, I'll try to explain better. Thanks
