I am hoping someone can help me determine the maximum allowable current carrying capacity for Aluminum Busbar. I need to install some busbar. I have 1/4" X 4" and 3/8" X 4" to choose from. What is the ampacity of each? Would you please tell me how to figure this out and cite reference, if possible? Thank you all so much! I really like this board!
What temperature rise above what ambient? What is the conductivity of the conductor (an old book shows two types of aluminum EC - 61%IACS and EC-T61 - 57%IACS)? What is the orientation of the bars, flatwise or on edge? Are bars mounted above each other (stacked)?
For example: 30 deg C rise over 40C ambient, still but unconfined air EC-T61 aluminum Edgewise orientation, bars spaced at least one thickness apart. AC 60hz current
It sure is nice to have an old Anderson Reference book. Mine is a '64 version also, and I use it many times to get information not readily available. I wish they would reprint it, or publish it on the web.
