In the early days, there was minimal consideration given to planning wiring installations. However, with the introduction of electricity supply from the grid, premises that utilize electricity now receive power from large sources. As a result, proper planning and design have become crucial. Electricity, like fire, can be an excellent servant, but if it is not properly controlled and used, it can pose significant dangers. Recognizing the necessity for organized methods of wiring and installation work, various regulations, requirements, recommendations, codes of practice, and similar guidelines have been established. Some of these guidelines are mandatory and enforceable by law, while others are merely recommendations.
