- 3. Current Carrying Capacity of Busbar Trunking System 1L Basis of Current Carrying Capacity The current-carrying capacity (In) of a busbar trunking system relates to continuous loading and is declared by the manufacturer based on tests to IEC 61439-6 (busbar trunking). The current-carrying capacity is designed to provide for satisfactory life of the system, subject to the thermal effects of carrying current for sustained periods in normal service. @www.linkedin.com/in/raykhanlightning

Editor's Notes
- This is an example of a Title Slide. We need to convey Life Is On in everything we do, so try to lead with compelling images that are vibrant, authentic, and human. The human element should be apparent and within the context of a segment that we touch. To keep this PowerPoint template file size reduced, we included a small library of image choices in the Slide Master (under View). You can also get them from the SE Asset Library: https://schneiderelectric.telescopeondemand.com
- Hi I am Ray Khan I would like to take a moment before we get started, just to Thank You for the priviledge and opportunity to share with you the (SS638 Singapore Code of Practice for Electrical Installation) that I have learned from my career I respect you for the fact that you all that have decided to click on this video Shows you are the person who want to truly want to learn and improve the (quality of your design and electrical installation ) that is commited to electrical safety of the users And what I can give to you, if you will to pay attention for small bite 15 min video that we are working initiative with the marketing comm team Per video 15mins, I will do my best to help you be equipped with the fundamental knowledge of this code so that you can implement into your daily work
- BusBar Trunking System is commonly used in Generation, Transmission, Distribution and even Conversion of Electrical Energy. When It comes to the concern of Current Carrying Capacity, it stated in SS638:2018 that the Busbar shall be tested to IEC61439-6 (Busbar Trunking) So what is IEC61439-6 and what does it entail
- IEC 61439-6:2012 lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low voltage Busbar Trunking System Below are some key points where IEC61439-6 provides a Guideline for Busbar Trunking System: 1) Busbar Trunking System does not Exceed 1000Volts (A.C System) 2) Busbar Trunking System does not Exceed 1500Volts (D.C System) 3) The Standards ensure the following verification is met Voltage Drop Phase Conductor Design Verification & Specification Schedule Fault Loop Zero Sequences Impedances Fault Loop Resistance and Reactances Magnetic Field Determination Mechanical Load test (Straight Unit and Joints) Verification with Fire Barrier Rated Diversity Factor (Tap Off Unit) Conditioning of Thermal Cycling Test
- When Selecting what Size and Dimension of the Busbar Trunking System to Use. There are 4 Essential Factors to Consider
- Centralized distribution gives greater independence of circuits, reducing the consequences of a failure from power availability point of view.
- In centralized layout, each load is connected directly to the power source Centralized distribution gives greater independence of circuits, reducing the consequences of a failure from power availability point of view.
- In distributed layout, loads are connected to sources via a busway. This type of distribution is well adapted to supply many loads that are spread out, where easy change is requested or future new connection
- The benefits of Centralized distribution gives greater independence of circuits, reducing the consequences of failure from a power availability point of view. And yet the benefits of using of decentralized distribution with busway is a way to merge all the circuits in one: it makes it possible to take into account the diversity factor (ks), which means cost savings on conductor sizing The choice between centralized and decentralized solutions, Above are the Key Factors in favour of layout If I have Load distribution for localized loads (high unit power loads) , it is better to choose Centralized LayoutIf my installation require Installation flexibility: Eg: moving of workstations, equipment etc…), it is better to choose Decentralized Layout If my installation have even load distribution ( uniform distribution of low or medium unit power loads) it is better to choose Decentralized Layout
