What You'll Learn
Electrical safety
There are many hazards that can cause electrical injuries. These include contact with power lines, a lack of ground-fault protection, a missing or discontinuous path to the ground, improper use of equipment, and the incorrect use of extension and flexible cords.
To ensure electrical safety, it is important to follow certain practices. When working with electricity, remove all metal jewellery, rings, and watches. Never work with electricity when your surroundings or tools are wet. Always use Ground Fault Interrupters (GFI) when working outside, near water, or with extension cords. De-energise all electrical equipment before starting any service or repair work, and always verify that equipment is de-energised before beginning work. If you are not a qualified electrician, you should not attempt to service electrical equipment.
In terms of electrical safety at home, it is important to use lithium-ion batteries and chargers correctly. When purchased and used correctly, these batteries are safe, but there is a risk of fire and injury if uncertified products are used.

Electrical theory
One of the key aspects of Level 1 electrical theory is understanding the basic concepts of electricity, such as what electricity is, how it behaves, and how it can be measured. Students learn how to use tools like multimeters to test electrical properties such as resistance. They delve into the world of circuits, exploring series and parallel circuits, and calculating total resistance in these setups. This knowledge is essential for safely designing and working with electrical systems.
Level 1 electrical theory also introduces students to electrical codes and standards. In the US, this includes the National Electrical Code (NEC) and National Electrical Manufacturers Association guidelines. Students learn how to interpret and apply these codes to ensure their work complies with industry standards and safety regulations.
Additionally, students are taught about the various components of electrical systems, such as different types of boxes, conduit, and raceway systems. They learn how to calculate fill requirements for outlet adjunction boxes and how to bend, cut, and thread conduit. This knowledge is crucial for installing and maintaining electrical systems in a safe and effective manner.
Overall, Level 1 electrical theory provides a comprehensive introduction to the world of electricity and electrical systems. It equips students with the foundational knowledge and skills they need to progress in their electrical education and careers, emphasizing both theoretical understanding and practical applications.

Installation requirements
The NEC is a widely adopted model code for the safe installation of electrical wiring and equipment. Students learn how to use the NEC to find installation requirements, covering various types of boxes and how to calculate fill requirements for outlet adjunction boxes under 100 cubic inches (1,650 cubic centimetres).
The curriculum also covers raceway systems and their installation, including an introduction to various types of conduit bodies and the methods for hand bending conduit, such as 90-degree bends, back-to-back bends, offsets, and saddle bends. Students also learn how to cut, ream, and thread conduit.
Additionally, Electrical Level 1 provides an overview of conductor types, cable markings, and colour codes, and ampacity derating, which are all crucial factors to consider during installation. This level of training ensures that students develop a strong foundation in electrical installation requirements, safety practices, and industry standards.

Raceway systems
An electrical craft, the NCCER Level 1 course introduces students to the electrical trade with foundational training. This includes instruction in electrical safety, electrical circuits, electrical theory, and the National Electrical Code (NEC). Level 1 students also learn about device boxes, hand bending, raceways and fittings, conductors and cables, basic electrical construction drawings, residential electrical services, and electrical test equipment.
Raceways can be installed underground or on the surface. Underground raceways are typically buried under flooring in buildings with many cables and wires. Surface raceways, on the other hand, are usually located in walls and are common in residential homes and offices. Surface-mounted raceways allow wires to be concealed, making the environment safer and more aesthetically pleasing.
Students in the NCCER Level 1 course will learn about raceway systems and their installation requirements as part of their introduction to the NEC and electrical systems in general.

Conductor types
Electrical Level 1 introduces students to the foundational knowledge of the electrical craft. This includes essential topics such as electrical safety, electrical circuits, electrical theory, and an introduction to the National Electrical Code. Students will also learn about device boxes, hand bending, raceways and fittings, conductors and cables, basic electrical construction drawings, residential electrical services, and electrical test equipment.
As part of their curriculum, students will explore the different types of conductors and their unique characteristics. Conductors are materials that facilitate the flow of electric charge or current. Metals, such as copper, aluminium, and silver, are excellent conductors due to their high number of free electrons, which promote mobility. Copper, for instance, is the standard to which other electrical conductors are compared. Silver, while a better conductor than copper, is often less practical due to its higher cost and susceptibility to tarnishing.
Aluminium is another widely used conductor, especially in home internal wiring, and it is often used in combination with copper. In some cases, non-metals can also exhibit good conductivity. For example, carbon in the form of graphite is an excellent conductor because its structure leaves one electron free for bonding. Ionic conductors, such as saltwater, are also good conductors due to their free-floating ions.
The geometry and temperature of a conductor influence its characteristic resistance. For instance, a thick copper wire has lower resistance than a thinner one of the same material and length. Additionally, an increase in temperature can lead to the expansion of the conductor, altering its geometry and resistance. However, the increase in temperature also provides more energy to the atoms and their electrons, enhancing their mobility.
Understanding the behaviour of conductors is crucial for electrical work, as highlighted in Electrical Level 1. This knowledge forms the basis for learning about conductor installations, conductor selections, and other advanced topics in subsequent levels of electrical training.
