Copper bus duct sizing.
Also known as bus bars they serve as connection points between wires with ring or spade terminals.
Free online copper busbar weight calculator on smi copper website.
Ampacity of the bus bar selected must then be verified by checking table 1.

Understanding bus bar ampacity charts.
This article presents a brief overview of ampacity charts for both copper and aluminum bus bar and shows how to interpret the data within.
The underside is sealed so the bars can be safely mounted to conductive surfaces.
A very approximate method of estimating the current carrying capacity of a copper busbar is to assume a current density of 2 a mm2 1250 a in2 in still air.

Originally a busway consisted of bare copper conductors supported on inorganic.
These bars are tin plated copper and have stainless steel terminals.
Covers protect the top of the bar and prevent accidental contact with live circuits.
There are a number of considerations that need to be recognized beyond the figures given in the chart.
Ampacities of bus bar systems of other configurations must be calculated taking into account size spacing number of bus bars and overall skin effect ratio.
