Recommendation About Cable Sizes and Breaker Rating

[BillP]

Dear Team,

Would appreciate if any recommendation &/or documentation regarding cable size calculation and breaker rating calculation for apc ups (3phase specifically) be shared. It may comprise of any parameters or formulas may better be used to size the cables and breakers accordingly.

yah, as usual it's helpful but to an initiator level, actually I wanted some thorough technical peep into the subject, and wanted to go through it in detail, if you can guide me to any particular document, which may consist of any FAQ from knowledge base or White Paper or may be any relevant article which can serve the purpose, that would be great.

I don't think we have any white papers/application notes (or at least I could not find any) @ http://whitepapers.apc.com - we only make recommendations based on the current draw and power requirements of our systems where as local code is what you need to follow. So in NAM, I'd probably pursue researching National Electrical Code - I imagine in your region you may have something similar as to where these standards and codes come from and why they are in place. Just some general electrical knowledge may also be something to research as well.

If anyone else has any recommendations or documentation, please let us know.
