  • Electrical – Wiring Methods, Components and Equipment for General Use
    Electrical – Wiring Methods, Components and Equipment for General Use Approved for Public Release; Further Dissemination Unlimited At the completion of this unit you shall be able to: 1. Utilize section Z of the Safety and Health Hazard Inspection Program Checklist to identify compliant and non-compliant safety behaviors. 2. Identify areas of concern requiring immediate action to mitigate or prevent a possible injury. Please use “Slide Show” to properly view this presentation! • Let’s start with a discussion of Electrical Safety. Whenever you work with electrical devices there is a risk of electrical hazards, especially electrical shock. Risks are increased at maintenance and construction sites because many jobs involve electric power tools. Coming in contact with an electrical voltage can cause current to flow through the body, resulting in electrical shock and burns. Serious injury or even death may occur. Electricity has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires, and explosions. In 1999, for example, 278 workers died from electrocutions at work, accounting for almost 5 percent of all on-the-job fatalities that year, according to the Bureau of Labor Statistics. What makes these statistics more tragic is that most of these fatalities could have been easily avoided. • When an electrical shock enters the body it may produce different types of injuries. Electrocution results in internal and external injury to body parts or the entire body – often resulting in death. After receiving a “jolt” of electricity all or part of the body may be temporarily paralyzed and this may cause loss of grip or stability.

    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.

Predebon Date Abstract Autonomous system applications are typically limited by the power supply opera- tional lifetime when battery replacement is difficult or costly. A trade-off between battery size and battery life is usually calculated to determine the device capability and lifespan. As a result, energy harvesting research has gained importance as soci- ety searches for alternative energy sources for power generation.

  • Operators Manual for KDS Manual Provides Installation, Operation, and Maintenance Instructions
    Operators Manual for KDS Manual provides Installation, Operation, and Maintenance Instructions Model: KDS Kitchen Distribution System Form#: OM015_KDS Date: 11-2016 - Rev1 INTRODUCTION Upon receipt of the Halton KDS (Kitchen Distribution System), inspect the crates immediately for any shipping damage and notify the carrier immediately if damage is found. Halton will not accept responsibility for any shipping damage, but will assist in helping to get a claim filed if needed. The HALTON KITCHEN DISTRIBUTION and SAFETY SYSTEM has been fully assembled and tested at the factory before shipment. When assembled at the installation, according to these instructions, all parts will mate properly and fit according to plan. It should not be necessary for any contractors to make internal modifications. The KDS system is designed for flexibility in satisfying equipment additions and relocations. Once the factory designed KDS is assembled in the field per the original design, movement or additions of Outlets / Gas drops / Water drops / Steam drops etc. is allowed. The “Trade” performing the work shall use UL listed or UR recognized components and will not make additions that will exceed the unit’s UL rating. Note: Refer to the following instructions and drawings for proper installation. HALTON shall not be responsible or liable for improper operation of the KITCHEN DISTRIBUTION and SAFETY SYSTEM due to any design or assembly modifications, or error, of other engineers or contractors. IMPORTANT INFORMATION Read these instructions carefully before commencing installation or maintenance on unit. In order to ensure the performance of the system it is essential that routine maintenance is carried out in accordance with the following instructions.

    Electrical Wiring - OR - WHY DO WE NEED ALL THIS COPPER?! BUREAU OF TRAFFIC OPERATIONS Signals, Lighting & ITS Systems Installation and Inspection Training Objectives • Identify Types of Wires – Size – Insulation • Installation Methods – Pulling – Blowing • Grounding and Bonding – How, where and why – Testing • Splicing conductors – Where are splices permitted? – Splice “kits” – Testing • Terminations – Proper cable/wire termination methods • Electrical Services – Installation and Service Connection • Documentation – Asbuilts – LABEL!! BUREAU OF TRAFFIC OPERATIONS Signals, Lighting & ITS Systems Installation and Inspection Training Wire Size Wire size is measured in AWG (American Wire Gauge) • The AWG number identifies the size of the conductors the smaller the number the larger the diameter (AWG 0000 – 0.46 in , AWG 18 – 0.04 in) • NEC defines process for calculating wire size based on Current, Voltage and length of wire. • Changes in routing may require a change in the wire used to cabinets or field elements. • Most household wiring is usually 12 or 14 AWG • DOT Signal, Lighting and ITS wires range from 18 AWG for communications interconnect to 00+ for power service. • AWG # wire can be either solid or stranded . BUREAU OF TRAFFIC OPERATIONS Signals, Lighting & ITS Systems Installation and Inspection Training Determining Conductor Size • Typically ampacity and sizing is determined by the designer and provided on the plans • De-rating of conductors may need to be determined if the cable routing is revised by field personnel or final job layout – Derating process is documented in the NEC. Generally requires a review of installation conditions and cable rating.
