Power Supply System Design Code

[Leo Li]

Hi Sir, Is there any NFPA or other US code to be followed for power system design(13.2 KV or below )? Locally (CN) there is code to follow as below photo. Itry to find the similar US code. Thanks!

At the utility generation level? Utility distribution? User?

Power supplies are most likely designed to a UL standard for the US. This would be for power supplies under 480 vac. Power supplies are not premise wiring and are not under the scope of the NEC
Recommend you start with UL, contact them to discuss the standard and the listing process.

Tom I think he means NESC, like utility power supply.
looking at it here:

GB 50052-2009 English Version, GB 50052-2009 Code for Design Electric Power Supply Systems (English Version) - Code of China

GB 50052-2009 English Version - GB 50052-2009 Code for Design Electric Power Supply Systems (English Version): GB 50052-2009, GB/T 50052-2009, GBT 50052-2009, GB50052-2009, GB 50052, GB50052, GB/T50052-2009, GB/T 50052, GB/T50052, GBT50052-2009, GBT 50052, GBT50052

Leo I believe what your looking for is a national standard for designing power grids.
In the U.S such standards are adopted by the individual states, and are not all in one standard like that one is.
For starters
There is the National Electric Safety Code (NESC) :

IEEE SA - The National Electrical Safety Code® (NESC®)

Published exclusively by IEEE and updated every 5 years to keep the Code up-to-date with changes in the industry and technology, the National Electrical Safety Code® (NESC®) sets the ground rules and guidelines for practical safeguarding of utility workers and the public during the installation...

Thank you very much!

yes, as per load level to decide to utility power system design.Thanks!

Its all terminology, power supply to me is a wall wart
