BS 4568 and EN 61386 are standards related to steel conduits and fittings used in electrical installations:
1. **BS 4568**: This is a British Standard that specifies the requirements for steel conduits used in electrical installations. It covers the use of galvanized steel to prevent corrosion and includes specifications for both metric (BS4568 Part 1) and imperial (BS4568 Part 2) systems. The standard is suitable for both indoor and outdoor installations, including industrial and commercial settings.
2. **EN 61386**: This is a harmonized European standard for conduit systems used for cable management in electrical installations. It covers various materials, including metal and non-metal conduits, with specific parts for Galvanized Iron (GI) conduits. The standard includes tests for mechanical strength, fire resistance, and corrosion resistance, and is widely adopted across Europe for a range of environments including residential, commercial, and industrial.
Both standards are crucial for ensuring the safety, reliability, and durability of electrical installations by specifying the necessary requirements for conduit systems.
