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.
Your subsystem must meet all of the following conditions:
• An insulated grounding conductor that is identical in size and
insulation material and thickness to the ungrounded branch-circuit
supply conductors. It should be green, with or without yellow stripes,
and is to be installed as a part of the branch circuit that supplies the
unit or system.
• The grounding conductor mentioned above should be grounded to
earth at the service equipment or other acceptable building earth
ground such as the building frames (in case of a high rise steel-frame
structure).
