The primary reason for grounding electrical systems is safety. The safety
ground is required by the National Electric Code (USA) and most other
local, regional, and national codes. In addition to safety ground, HP
requires that a dedicated (earth reference) ground be installed as a common
reference point for all system components. You should consult with your
HP CE and your electrician to ensure that your electrical system meets all
local and national safety codes.
