The ultimate performance of modern audio systems may be significantly constrained by signal contamination introduced by inappropriate grounding and interconnection practices. Fundamental principles of electromagnetism and linear circuits are reviewed. From this, a body of good engineering practice for grounding, shielding, and interconnection methods is developed. A logical, consistent grounding scheme is presented which strictly conforms to the requirements of the National Electrical Code, a model safety code widely adopted in jurisdictions in North America. Conventional grounded neural conductor mains power distribution is used, which may be single phase, polyphase, or multiple separately derived polyphase systems without constraint. The fundamental principles may be applied to mains power distribution systems conforming to other internationally established safety standards.
