The NEC section on electrical connections and splices is divided into several parts. The first part provides general requirements for making electrical connections, including the types of conductors and connectors that can be used, the methods for connecting conductors, and the insulation and protection of connections.
The second part of the section provides specific requirements for splicing electrical conductors, including the types of splices that can be used, the methods for making splices, and the insulation and protection of splices. The third part of the section provides requirements for testing and inspecting electrical connections and splices to ensure proper functionality and safety.
Introduction
The National Electrical Code (NEC) provides comprehensive guidelines for the safe installation and maintenance of electrical systems. Section 110.14 covers electrical connections and splices, establishing critical requirements to ensure proper functionality, safety, and reliability of electrical installations.
Scope of the NEC Section
NEC Section 110.14 applies to all types of electrical connections and splices used in electrical systems, including those in residential, commercial, industrial, and institutional buildings. It covers connections between conductors, as well as splices made to repair damaged conductors.
General Requirements for Electrical Connections
- Conductors must be properly sized and rated for the intended current and voltage.
- Connections must be made using approved methods and materials, such as wire nuts, terminal blocks, or soldering.
- Connections must be insulated and protected from physical damage and environmental factors.
Specific Requirements for Splices, The nec section that governs electrical connections and splices is
- Splices must be made using approved methods, such as wire nuts, crimp connectors, or solder.
- Splices must be properly insulated and protected from moisture and physical damage.
- Splices should be located in accessible locations for inspection and maintenance.
Testing and Inspection of Electrical Connections and Splices
Electrical connections and splices must be tested and inspected to ensure proper functionality and safety. Testing methods include continuity testing, insulation resistance testing, and load testing. Inspections should be conducted regularly to identify any loose connections, damaged insulation, or other potential hazards.
Maintenance and Repair of Electrical Connections and Splices
Regular maintenance is essential to ensure the ongoing safety and reliability of electrical connections and splices. Maintenance tasks include visual inspections, cleaning, and tightening of connections. Repairs should be made promptly to address any identified issues and prevent potential hazards.
