I am skeptical as to whether this component needs to be grounded at all; it's not conductive, so my intuition is that it isn't able to cause a shock. My question is basically (1) can a PVC pipe cause a static discharge.

Finding the Root Cause - of Power Cable Failures
I will discuss electric fields within cables. I will then go over with some examples how evidence discovered in the analysis may lead to the root cause of the failure. In this article, I will limit the discussion to medium voltage AC, 5 kV to 45 kV class cable systems. ELECTRICAL SAFETY HAZARDS HANDBOOK Electricity can be defined as the flow of electrons through a conductor. This is similar to the flow of water through a pipe. Electromotive force, measured in volts, causes the current to flow similar to a pump moving water. The higher the water pressure and the larger the pipes, the greater the water flow. In electrical
Standard Insulating Materials Used in Electrical Engineering.
Application of insulating materials. Cables and transmission lines:. Insulating material is generally used as a protective coating on electrical conductor and cables. Cable cores which touch each other should be separated and insulated by means of insulation coating on each core, e.g. polyethylene, cross linked polyethylene-XLPE, polyvinyl chloride-PVC...
