Wiring and Protection
NEC chapter 2 sets the general rules for wiring and protection of conductors. The codes also detail the use and identification of ground conductors and set parameters for identifying terminals and wiring systems. We also find standards for overcurrent protection, grounding and bonding and surge protection devices.
Wiring Methods and Materials
NEC outlines the wiring methods and materials you should use for residential and commercial buildings. The standards deal specifically with cables, conductors, boxes, fittings and raceways. We also choose the type and material of the cable based on the standards listed by NEC. The codes provide details about the installation and restrictions that come with wiring methods.
Violating the wiring rules can cause power quality problems and lead to massive cost.
Equipments for General Use
You need to use components as part of the electrical setup in any building. For example, fixture wires, switches, receptacles, switchboards, control panels and more. NEC also sets the codes for selecting and using various electrical components.
NEC also covers appliances, low-voltage lighting, fixed heating equipment, air-conditioning, refrigerators, motors and capacitors. You will also need to follow the standards outlined for generators and storage batteries.
Commercial facilities and buildings have a different set of codes to follow. You need strict standards for hazardous locations where the danger of electrical mishaps are more. NEC lists various zones and classes of locations and provides detailed standards for each location. The standards cover various industries such as commercial garages, bulk storage plants, health care, manufacture, agriculture, film and television and more!
Surprisingly, you also have codes for mobile homes, park trailers and even floating buildings.
A wide range of special equipment is covered under the NEC. From electric signs and office furnishings to solar photovoltaic systems and fire pumps- everything must comply with NEC. The list also contains industrial equipment like X-Rays, industrial machinery, electrolytic cells, electric welders and fuel cell systems.
Some regular things that we use every day also need to be NEC-compliant. Examples include fountains, swimming pools, elevators, artificially made and natural water bodies.
The NEC 700-series codes have to do with systems used in special conditions. Some of the systems are part of every building's defense system like fire alarm systems emergency systems. The codes also cover other equipment like energy storage systems, optical fiber cables, direct current microgrids and stand-alone systems.
Various communication devices we use in the present time needs to be NEC compliant. For example, we have to follow applicable standards for network-powered and premises-powered broadband communication systems and even communication circuits.
The range of codes you need to follow will be decided by your project and environment. What one type of building needs may not be the same that your building will also need. You need professional engineers to figure out the standards that apply to your design, building or project.
We can help you determine the codes that are applicable to your project and create a fully-compliant design. You have complete peace of mind when you work with our team as we ensure strict adherence to requirements and regulations.
