Electrical Works and LightingBefore undertaking any renovation project, it is important to carefully plan the electrical works and lighting. The number of power points and the type of lighting to be installed are some of the most crucial considerations, and homeowners often forget about these details until it is too late. This is because electrical works require rewiring or hacking false walls, and they must be planned before other stages. If not, homeowners run the risk of incurring extra costs when these work is discovered during the renovation phase. ElectricityElectricity is the energy that makes lights shine and devices turn on. However, electricity is dangerous if you get too close to it. It can even shock you if you touch it. For example, many people get shocked when they touch a doorknob. Lightning is very similar to electricity. If you've ever seen lightning, you know it can strike you as well. There are many ways to learn about how electricity works. The first step is learning about how it is produced. The process of making electricity began thousands of years ago. The discovery of electricity was attributed to the work of a French physicist, Andre-Marie Ampere. His experiment revealed that electricity and magnetism can work together. Later, a British inventor named William Sturgeon made the first practical electric motor. Electric circuitsElectric circuits are used to supply light and power to various electrical devices. A basic electric circuit consists of three components: a source of electrical energy, a lamp, and two wires that can carry electrical current. These three components must be connected in a closed circuit, so that the electrons in the electricity can flow freely from the source to the lamp or other device. Electric circuits can also be divided into two types, series and parallel. A series circuit contains only one path for electrons to flow, whereas a parallel circuit contains several components in parallel. Each component has an equal voltage, so the voltage flowing in a series circuit is the sum of all the voltages from each component. Electric lightThe Electric Light and Electrical Works Code govern all employers who carry out electric light or power line construction. The Code applies to all construction work, including excavation, concrete, overhead stringing of high-tension wires, and installation of transformers and circuit breakers. Listed below are some specific requirements for light and electrical construction. A series circuit requires all the devices in the circuit to be operational to produce the same current. The problem arises if one bulb burns out. Parallel circuits are different in that each light bulb has its own circuit. This means that the last light will still function if the other lights have already burnt out. Rigging electriciansThere are two types of electricians in film and television productions: On-Set Electricians and Rigging Electricians. Rigging Electricians set up temporary power networks, lay cables, and more lights. On-Set Electricians check their work and make sure everything is working properly. They also set up the lights for each shot. The best boy is the lead electrician on the set and runs the Electric Department. He supervises all the electricians and directs them. The best boy also hires crew members to help him with his work. The rigging electricians lay cables, put in lighting, and work under the direction of the rigging best. They are responsible for the safety of electrical equipment and must be familiar with tungsten and HMI lighting. They are often the first to arrive on the set and the last to leave. On large budget productions, they have several departments, while small-budget productions usually have just a few general electricians. Rigging electricians for lighting and electrical works are responsible for rigging heavy and hot objects. They may work under a Rigging Gaffer, who reports to the head gaffer of the Electric Department. Rigging electricians are typically certified by the Entertainment Stage Technologies Association to standardize basic skill sets and sake sets safer. Rigging electricians also go by other names, such as lamp operator and spark technician. Rigging gafferThe rigging gaffer is a technician in the electrical works and lighting departments. This person is responsible for the safety of the crew. He sets up and installs power distribution equipment. He also designs the rigging scheme and troubleshoots any problems that may occur. He also ensures that the cables and rigging units are labeled. Proper rigging means that lighting crews can easily access the power, and that nothing gets under the rigging gaffer. A rigging gaffer will have years of experience working on a film set. They may be part of a lighting crew, or work independently. Some of these technicians are also gaffers and supervise the best boys. These professionals will be in charge of pre-lighting on the set, as well as ensure that everything is in working order when the gaffer arrives. Rigging gaffers work closely with the director of photography to ensure that the sets are properly lit. |
