This blog is intended to educate consumers about the nature and benefits of copper in general and more specifically copper’s application in the electrical industry. To this end you will find a variety of articles that detail critical considerations necessary for buying copper electrical components and tips for simplifying the process.
We’re adding more articles weekly, so check back often for the latest information. If there’s a subject that you want to see covered, just drop us an email and we’ll be happy to address your needs.
Here’s our current list of articles and guides to aid you in your quest for information about the amazing metal: copper.
Use the following links to view Storm’s bus bar ampacity tables…
Table 1. Ampacities of Copper Alloy 11000 Bus Bars – Ampacities in this table are for buss bars having an emissivity of 0.4. This was observed on samples exposed for 60 days in an industrial environment, and it is probably identical to that of buss bars in service.
Table 2. Quick Ampacity Bus Bar Size Selector – Knowing the ampacity, designers and estimators can get the approximate buss bar size. Ampacity of the busbar selected must then be verified by checking Table 1.
Table 3. Effect of Emissivity and Number of Bus Bars on Ampacity – Data here show how higher emissivity improves ampacity. Multiple buss bars also affect ampacity in a nonlinear relationship. Ampacity may be raised by increasing heat dissipation through the use of convection cooling or surface treatments.
Table 4. Laminated Bus Bar Ampacity – Based on bus bar area cross section, width and thickness, and the relationship to resistivity, inductance and current rise associated with laminations.
