Busbars are used within installations for distributing electrical power from a supply point to a number of output circuits. They may be used in a variety of configurations ranging from vertical risers, carrying current to each floor of a multi-storey building, to bars used entirely within a distribution panel. |

In any electrical circuit some electrical energy is lost as heat which, if not kept within safe limits, may impair the performance of the system. This energy loss, which also represents a financial loss over a period of time, is proportional to product of the effective resistance of the conductor and the square of the current flowing through it. Designing for low loss uses more conductor material but leads to a lower working temperature, more reliable operation and, since the cost of lifetime energy losses is far greater than the cost of first installation, lower lifetime costs.

Pub 22 - Copper for Busbars  
Comprehensive guide to electrical, mechanical and thermal stress considerations in the design of busbar systems. 3rd edition, fully metricated and updated. 1996. 64pp.
D11 Busbar Design Software 
This program, based on the formulae found in CDA publication 22, calculates the current rating, size and working temperature of common configurations of copper busbars. The minimum size and the savings and payback periods that accrue from the use of larger sizes, up to the most economic, are calculated. The economic calculations take account of copper price, fabrication cost, load growth, discount rate and increases in energy costs. 1998.
Pub 116 Electrical Energy Efficiency 
Life time running costs must be taken into account when designing electrical installations or selecting replacement cables, motors and transformers. Both financial appraisal and technical consideration of electrical energy efficiency of motors, cables, busbars and transformers, with actual case histories showing savings to be made can be found in this book. 1997. 80pp.
