List of Standards and Codes Related to Grounding

Hi,

Here are list of standards and codes related to grounding, I made it as to remind:

API RP 540 page 36 to 38:
System grounding
"The following grounding practice is recommended:

1. System rated at less than or equal to 480 V that supply phase-to-neutral loads must be solidly grounded. These include 120/240-V, single-phase, three-wire systems; 208Y/120-V, three-phase, four-wire systems; and 480Y/277-V, three-phase, four-wire systems.
2. Low voltage (480-V and 600-V), three-wire systems should be either high-resistance grounded or solidly grounded.
3. All other plant distribution systems may be resistance grounded. These include 2,400 B through 34,500-V, three-phase, three-wire systems. (Open wire distribution may require solid grounding.)."

Equipment grounding
Structure and Process Equipment
"Steel building frameworks, switchgear structures, and similar installation should be grounded at several points (at least two point per structure) with substantial connection to the grounding system grid. Tanks, vessels, stacks, exchangers, and similar equipment not directly supported by or bolted to a grounded supporting structure should be grounded using a minimum of two connections to the grounding system grid...."

Motors and Generators
"Motor and generator enclosures should be connected to the overall plant grounding system..."

GPSA Engineering Data Book page 18-33:

"...Equipment grounding is separate from system grounding. Both are required to provide adequate protection."

If you know another which do not listed here. Do not hesitate to inform me.

That's all.
