Parallel Conductor Sizing

[cdnewman]

Hey folks! Real quick question. Does anyone have a link to a sizing chart for parallel conductors? I know they are out there, but thought it would be quicker to just ask. Planned on 300mcm, but due to availability, need to run parallel cables. Any help would be great!!

Calculation is simple, divide ampacity needed by number of conductors that will be in parallel - result is ampacity needed for individual conductors - but keep in mind you can't parallel anything smaller then 1/0 for general power/distribution applications.

Are you adding a raceway now that you are paralleling?

To my knowledge, there is no "chart" due to the factors mentioned in the above post.
The "equivalent" conductor will depend on insulation type (75°,90°), and number of conduits and number of current carrying conductors.
