Protective Earth
Figure 45.
Note:
Cable shielding (screening) shall be connected to the TPPR enclosure's common earth point only, and both shall be fully
isolated from all other metal bodies.
Cable armour and/or steel conduit and/or metal junction boxes and/or metal sensor bodies must be connected to protective
earth (ground) in the field and shall be kept fully isolated from contact with cable shielding (screening) and from contact with
TPPR enclosures or metal enclosure glands.
Long cable runs should be earthed in the field at regular intervals but be careful to avoid earth (ground) loops.
