BS 7671: 2001 (incorporating Amendments No 1: 2002 and No 2: 2004) has requirements for protection against electric shock, and lists a choice of five basic measures which shall be used to protect against indirect contact. This guide explains the theoretical principles and practical implementation of measures for equipotential bonding and lightning protection of PV systems in general – and of S:FLEX mounting systems in particular – based on the relevant technical regulations. This is also how DIN VDE 0100-200 defines the term. Supplementary bonding is the practice of connecting two conductive simultaneously accessible parts together to reduce the potential difference between the parts. – Induced currents from lightning which could damage the electric equipment. Equipotential bonding conductors do not carry operating currents and.
[pdf] NEC Article 392 explains cable trays, their components, appropriate wiring methods for cable trays, and instances where they are and are not permitted for use. It also focuses on construction and installation practices for cable trays. Here is the summary of the main points found. The primary rulebook used in the safe use of cable trays is NEC Article 392. You should consider it as a series of instructions that make the buildings resistant to. In modern building construction, the proliferation of electrical, data, and audiovisual cabling has transformed cable management from an afterthought into a critical planning consideration. This guide breaks down the process step by step.
