basic electrical electronics equipment servicing

Short Circuit — When one part of an electric circuit comes in contact with another part of the same circuit, diverting the flow of current from its desired path. Disconnect the power source before servicing or repairing electrical equipment. The utility company handles the line portion of your service, which includes everything up to the attachment point on your house. These components are basic elements that are used to design electrical and electronic circuits. If the breaker trips again—without the appliance plugged in—you must call an electrician. Always remind them not to play with electricity. If you ever read about current passing through human body you will know, so remember – work with one hand only.

A lineman’s plier, or a bull nose plier with a wire cutter, and at least 8″or 9″ handles is also an essential part of the electrical tool list. By request:- A basic guide to identifying components and their functions for those who are new to electronics. pliers, cutters, crimpers, strippers, wire wrapping tools, etc. Regards. Electronic/bench testing equipment and supplies simulate operating conditions and perform functional tests to see if devices are working correctly. Like in previous rules – Always disconnect the power FIRST. Thank you for sharing it. I am an electrician who has low power, but I need to be inquisitive to know more high-quality electricity will connect more into this page and be educated on learning electronic things, thank you, Thanks for these live saving tip. The 101 Basics Series provides a solid foundation of power distribution and control equipment knowledge. Questions are constantly asked about what equipment is needed to repair or restore antique radios and electronics. In this way, the proper operation of the DUT can be proven or faults in the device can be traced. The breakers for the branch circuits fill the panel (usually below) the main breaker. Disconnect the power source from the circuit breaker or pull out the plug using a leather belt. A basic electronics device or instrument used to measure voltage or electrical potential difference between two points in electrical circuits is known as voltmeter. We use these for cutting, bending, twisting wires, etc. It helps you. These safety rules are lifesavers for many. 5 0 Item Code Full CourseTitle (IncludesTex t b o o k ) P r i c e B K E E I n t roduction to Electricity and Electro n i c s Item Code R e q u i redTex t b o o k E E . It’s always better to be safe than sorry. 14 likes. In other words, the net current in a node is zero or 0 = I(in) – I(out). Soldering Tool Stand 9. The major electrical and electronic components used in electrical and electronic projects mainly involve these components like resistors, capacitors, fuses, transistors, integrated circuits, relays, switches, motors, circuit breakers, etc. Wonderful explanation about safety rules to be applied to prevent injuries and Equipment damages or even death. If I may ask can I include these Rules in our Safety Policy? The most popular option is to use clear plastic storage boxes for storing parts. The service panel contains a large main breaker that is the switch controlling the power to the rest of the circuit breakers inside the panel. There are two types of voltmeters: analog and digital. Short cuts savings are short lived!!!!!!!!!!!!!! Thank you so much for sharing the information. Power is always present in the utility service lines and the electric meter unless it is shut off by the utility. I have found quite a few EEP articles being very useful to me in the last 5 years.. Take this opportunity to thank Edvard and his team and wish him and all EEP readers a very happy 2020. Your home’s wiring consists of a few different types of wiring, including non-metallic cable (commonly called Romex), Bx cable, and wiring concealed in conduit. Usually only a few kilowatts. Older panels were sized for 150, 100, or fewer amps (amperes). The problem could be in the chandelier’s wiring (open wire connection, open connection in socket), or in the bulb itself (burned-out filament). Turning off a breaker shuts off the power to all of the devices and appliances on that circuit. Equipment producing a “tingle” should be disconnected and reported promptly for repair. Portable Electric Drill 3. NM cable is the most common type of circuit wiring. Question 1 A chandelier has five light bulbs in it, and one of them is not working. The programme is a presentation by Bikash Agarwal, Assistant Professor, Electronics and Communication Engineering Technology, Don Bosco. Hand Tools Specification 1. Please don’t make fun of this rule if you already know this (and you probably already know if you are reading these lines) and remember that if something bad occurs – you probably won’t have second chance.
