Equipotential bonding requirements for cable trays

Equipotential bonding requirements for cable trays

NEC Section 318-6(a) states that cable tray is not required to be mechanically continuous but it must be electrically continuous and bonding shall be in accordance with NEC Section 250-75. 2 requires that; "In each installation main protective bonding conductors complying with Chapter 54 shall connect to the main earthing terminal extraneous-conductive-parts including the following: (i) Water installation. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. This also applies to systems that are located in potentially explosive atmospheres.

Optical module packaging wire bonding

Optical module packaging wire bonding

PWBs are a high-yield, low-insertion-loss, and high-throughput versatile method of packaging photonic components such as chip-to-fiber, laser-to-chip interconnects. A promising approach is to create "photonic wire bonds" (PWBs), namely optical waveguides that look similar to conventional electrical wire bonds. The Photonics Packaging Group at the Tyndall National Institute in Ireland is a Europractice partner and offers packaging and integration services for the Silicon Photonic Integrated Circuits (Si-PICs) fabricated in the MPW runs. Built on advanced 3D nano-printing technology, PWB is inherently a fully automated process and provides a high degree of design flexibility. Here we demonstrate low loss (2 dB per channel) connections between a single mode fiber array and tapered silicon waveguides down to 5 K using polymer based photonic wire bonds (PWBs).
