However these rules are pretty much universal and apply at all power levels. thanks yoy for th guud insigtfl cumennt goud bles, Sir, All above safety rules are very fine. In many circuits, these components are used to build the circuit, which are classified into two categories such as active components and passive components. Directions: On a separate piece of paper, classify the different kinds of hand tools according to their specification in Consumer Electronics Servicing. Please contact student services for individual lesson and textbook pricing. I will learn from you and I will sharing these knowledge. Make sure electrical equipment is properly connected, grounded and in good working order. Televisions, lights, computers, freezers, vacuums, and toasters are all good examples of devices that can be plugged into an outlet. We use these for cutting, bending, twisting wires, etc. If equipment must be used in such areas, mount the equipment on a wall or vertical panel. In simple terms, electricity is supplied to the house on the hot wires. De-energize open experimental circuits and equipment to be left unattended. Afterall, it’s stupid to do so. When it is necessary to touch electrical equipment (for example, when checking for overheated motors), use the back of the hand. They’ll learn how to use electrical test equipment in their everyday jobs before moving on to an in-depth discussion about major electrical components, where and how these electrical components work, and their purposes within electrical systems.

These components have a minimum of two terminals which are used to connect to the circuit. Thank you for the electrical safety tips! If water or a chemical is spilled onto equipment, shut off power at the main switch or circuit breaker and unplug the equipment. The utility company handles the line portion of your service, which includes everything up to the attachment point on your house. Examples of these include: This law basically states that current into a node will equal the current out of the node. The most popular option is to use clear plastic storage boxes for storing parts. Your home's electricity starts with the power service and electric meter. Devices are all the things in the house that use electricity, including switches, receptacles (outlets), light fixtures, and appliances. Fundamentals of Electricity . REFERENCES. However, power is always flowing into the panel and to the service lugs even when the main breaker is shut off unless the power is shut off at a separate disconnect switch. Do not rely on grounding to mask a defective circuit nor attempt to correct a fault by insertion of another fuse or breaker, particularly one of larger capacity. You never know. Get access to premium HV/MV/LV technical articles, electrical engineering guides, research studies and much more! 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. A standard panel today provides 200-amp (ampere) service. When it is necessary to handle equipment that is plugged in, be sure hands are dry and, when possible, wear nonconductive gloves, protective clothes and shoes with insulated soles. Resistors come in a variety of resistance values (how much they resist current, measured in units called ohms and designated by the symbol Ωand power ratings (how much power they can handle without burning up, measured in watts). Extension cords may not be used as permanent wiring and should be removed after temporary use for an activity or event. I was trying to explain my 7 years old daughter how dangerous electricity is. Questions are constantly asked about what equipment is needed to repair or restore antique radios and electronics. Basic Electronics: Getting started with basic electronics is easier than you might think. Older panels were sized for 150, 100, or fewer amps (amperes). I really liked the hands on troubleshooting. The work area doesn’t need to be fancy and you could even build your own electronic workbench. Wire size is given in its gauge number. Electronics Class: While it may seem intimidating at first, learning electronics is fun and easy. Screwdriver 4. The meter measures the amount of electricity your home uses and is the basis for the charges on your electric bill.

We have contractors phone us asking for anti-static boots where they should be using electrical and vice versa….common guys…. Electronic components are basic discrete devices in any electronic system to use in electronics otherwise different associated fields. Thanks. Circuit layouts and schematic diagrams are a simple and effective way of showing pictorially the electrical connections, components and operation of a particular electrical circuit or system. Never handle electrical equipment when hands, feet, or body are wet or perspiring, or when standing on a wet floor. Very logical. A single circuit may contain multiple switches, receptacles, fixtures, and other devices, or it may serve only a single appliance or receptacle. From there, it's called the load side, and everything on the load side is your responsibility. Thank you Brunolda. People depend on electricity constantly, and when the power goes out in a storm or there's a tripped breaker or another problem in an electrical circuit, understanding the basic components of an electrical system can help you get things running again. It’s NEVER a good practice to contact live conductors even with the back of your hand. The latter is called a dedicated circuit. The utility company's service cables (whether overhead or underground) extend to your house and connect to the utility's electric meter. After passing through the meter, your electrical service feeds into your home's main service panel, commonly known as the breaker box. Regards.

It develops and publishes scientifically established specifications for data monitoring in a practice guide (Praxishilfe). Hack saw 6. If you're running a high-demand appliance, such as a vacuum, toaster, or heater, and the power goes out, you've probably overloaded the circuit. I’m thinking of doing some electrical wiring myself in my new home, but I want to be sure that I stay safe. There are single-pole, three-way, four-way, and dimmer switches. A basic electronics device or instrument used to measure voltage or electrical potential difference between two points in electrical circuits is known as voltmeter. Air ionizers and antistatic systems and supplies reduce static electricity to help ensure a safe environment for building and testing electronic devices. The problem could be in the chandelier’s wiring (open wire connection, open connection in socket), or in the bulb itself (burned-out filament). Move the appliance to a different circuit and reset the breaker by switching it to the ON position. It is recommended that you stay away from live wires and make sure that these are far from the reach of children. Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). Objective: Explain basic electrical principles. This is a quick overview int… Strictly speaking, an Active Component is a device that acts as a source of energy, like a battery. The German Environment Agency (UBA) collects data from producers, local authorities, distributors and waste disposal companies and processes it to meet reporting obligations to the European Commission. Power is always present in the utility service lines and the electric meter unless it is shut off by the utility. Metal Files Wonderful explanation about safety rules to be applied to prevent injuries and Equipment damages or even death. Nice Instructions I am thankfull of you for this work. If you can perform and if it safe then try using only one hand and keep the other hand on your side away from the electric circuits. There may be a dangerous fault situation in the circuit. Two large "hot" wires connect to big screw terminals, called lugs, inside the service panel, providing all the power to the panel. Usually only a few kilowatts. Achieve clarity on your volts, ohms and amps for normal and faulted circuits! Basic electrical electronics equipment servicing. Thanks. Thus, if accidental shock were to cause muscular contraction, you would not “freeze” to the conductor. If you put resistors next to a penny, you get an idea of how small they are.
