Project Standards#
This page is where you will find the acronyms, definitions and references/citations that are common for the project.
Acronyms#
Definitions#
- Arc Flash#
Result of a rapid release of energy due to an arcing fault between a phase bus bar and another phase bus bar, neutral, or ground.
- Arc Gap#
Minimum distance between conductors used in the calculations for arc flash analysis
- Calorie#
The unit of energy required to raise the temperature of 1 gram of water by 1oC from a standard initial temperature.
- Incident energy.#
Amount of energy impressed on a surface, a certain distance from the source, generated during an electrical arc event. Typically, this is measured in cal/cm2.
- Protective device#
Component used to interrupt current flow such as circuit breakers, fuses, relays, during undesirable system conditions.

Document Control#
Many companies have document control strategies that includes databases, etc.
Project Revision Numbering#
We start with letters (A, B, C, …) with the very first issue being Rev A. While this revision is in progress all references WITHIN the document will show a Rev Aw with the date empty. If you are looking at a document with Aw and/or no date, that is an uncontrolled document and may not be the most current.
When the document is ready to be issued it will be modified with a Rev A and the date of issue will be included. A PDF of this document will be made with the file name YYYYMMDD-REVA-<filename>.pdf. This is the only controlled copy. Once this PDF is created the working document will be revised to rev Bw and work will continue.
When the document is ready for release and/or the scope of the initial project is complete, the revision changes to numbers, starting at 0.
When Rev 0 is sent, and there are changes the document will be changed to 1w and work will continue.
