Guidance Notes on Recommended Specifications of Junction Box and Cable Tray for Offshore Application GUIDANCE NOTES ON RECOMMENDED SPECIFICATIONS OF JUNCTION BOX AND CABLE TRAY FOR OFFSHORE APPLICATION FEBRUARY 2018 American Bureau of Shipping Incorporated by Act of Legislature of the State of New York 1862 2018 American Bureau of Shipping. All rights reserved. ABS Plaza 16855 Northchase Drive Houston, TX 77060 USA Foreword Foreword These Guidance Notes provide ABS recommendations for the design and construction of cable trays and junction boxes. These Guidance Notes are applicable to fixed and floating offshore structures as well as drilling units. These Guidance Notes provide recommendations and best practices for standard specifications of certain electrical and instrumentation components thus improving cost efficiency (i.e., design man-hours, operation and maintenance costs), and increasing predictability of operation without compromising quality and safety in offshore structures and units. The recommendations in these Guidance Notes are based on industrial experiences, project experience, shipyard practices, manufacturer’s data sheets, national regulations, international standards, and ABS Rules. These Guidance Notes become effective on the first day of the month of publication. Users are advised to check periodically on the ABS website www.eagle.org to verify that this version of these Guidance Notes is the most current. We welcome your feedback.

Page 26 1. CONDUCTORS Conductors are defined as materials that easily allow the flow of _________. Metals are _______ conductors while insulators are ______ . The 2 common metals used for conductors in the electrical trade are: ___________ and ______________. Aluminium has become more prevalent for larger C.S.A. conductors as it is cheaper and lighter but more brittle than copper. Current/ Copper/ Aluminium Thermoplastic-sheathed cable (TPS) consists of an outer toughened sheath of polyvinyl chloride (PVC) (the thermoplastic element) covering one or more individual cables which are PVC insulated annealed copper conductors. It is a commonly used type of wiring for residential and light commercial construction in many countries. The flat version of the cable with two insulated conductors and an uninsulated earth conductor all within the outer sheath is referred to as twin and earth. In mainland Europe, a round equivalent is more common. Flat cables (or festoon cables) are made in PVC and Neoprene and are used as trailing cables for cranes, open filed conveyors and shelve service devices. Flat cables offer the advantages of extremely small bending radius’s, high flexibility and minimum wastage of space.

Industrial MI Wiring Cable
Industrial MI Wiring Cable Installation Manual for Alloy 825 Sheath Cable Wiring Systems Important Safeguards and Warnings WARNING: FIRE AND SHOCK HAZARD. nVent PYROTENAX mineral insulated (MI) industrial wiring cables must be installed in accordance with the requirements of national and local codes and standards, the installation instructions in this manual, and the customer’s specification. Read these important safeguards and carefully follow the installation instructions. • Ensure the cable has been stored properly and is in good condition prior to commencing installation. • Always use safe working practices when installing cables, observing OSHA and other national safety rules. • Store cables indoors in a clean, dry, covered area, if possible. • During the time that the cables are exposed and during cable pulling activities, protect cables from nearby or overhead work to prevent damage to the cable sheath. • Do not pull cables around corners that have sharp edges, such as corners in cable trays, or other obstructions. • Prevent damage to cables by removing any abrasions or sharp edges from surface of support system. • Damage to cables or components can cause sustained electrical arcing or fire. Do not energize cables that have been damaged. Damaged cable or terminations may need to be repaired or replaced. Damaged cable should be repaired by a qualified person. • When installing cables which may be exposed to hydrocarbon flash fires, use only steel or stainless steel in the support system. ii | nVent.com Table of Contents General Information -

3. the Electrical Cabinet
V1.0- 9.01.2015 Page 1 of 68 Preface, Our long experience enables us to offer our customers integrated high-tech devices, from in- house development, manufactured in recognised industrial conditions and reaching the top quality for installers and end users. With standalone and modular concepts we are able to offer maximum flexibility for field applications. These innovative products are developed and manufactured to the highest level achieving an excellent level of quality. The following guide lines which include real world examples as illustrations aim to benefit planners, installers and commissioning engineers, the theme is to provide an approach to diagnostics and troubleshooting of devices housed within and around a technical cabinet. Modern devices are based on advanced electronics technologies, with this the accuracy is higher and the measurement faster than in previous generations. This greater precision and accuracy requires an environment with the same attention to detail. In the field more often these devices are mounted together with Frequency Converters (FC), Power switched mode power supply elements, commonly used for better and more accurate pumps management and ventilation systems, however due to the way these devices function they can affect other devices by propagating Electromagnetic distortion waves or electromagnetic interference (EMI) which disturbs many electronic systems, irrespective of the colour of the box or the label or mark stamped on the bottom. This booklet is the fruit of the collected experience over recent years from many staff. It is the result of knowledge exchanged and transferred, applied and implemented, we hope it will bring support for field engineers, planners, programmers, project managers, technicians and all people getting in touch with this area. -
