Installation of Double-Door Distribution Box in Bahrain

Double-door distribution boxes in Bahrain must comply with EWA regulations, use licensed equipment, and follow proper installation standards for safety and functionality.

Regulatory Compliance

In Bahrain, all electrical installations, including double-door distribution boxes, must adhere to the Electricity and Water Authority (EWA) Regulations for Electrical Installations, which are based on IEC, IEE, and Kuwait standards but adapted for local conditions . Any deviation from these regulations requires approval from the Electricity Distribution Directorate (EDD) . Engineers and contractors are advised to check for periodic amendment sheets to ensure compliance with the latest standards.

Equipment Requirements

Double-door distribution boxes must be EWA-licensed and certified according to GSO, IEC, or BS standards . Typical specifications include:

• Three-phase 415V, 50Hz AC supply or single-phase 240V, 50Hz AC supply depending on application .
• MCBs (SP, DP, or TP) for circuit protection.
• ELCBs and isolators for safety and earth leakage protection.
• Copper tinned coated bus bars, rated for 150 amps.
• Surface or flush mounting with sufficient space for cabling and maintenance.
• Comprehensive cable entry facilities and universal fixing options.
• Optional higher IP ratings for enhanced protection in harsh environments.
• Basic colors are white or grey, with optional custom colors available .

Installation Guidelines

1. Location and Mounting: Install the distribution box in a dry, accessible area with adequate ventilation. Ensure it is mounted securely on a wall or within a recessed cavity if flush-mounted .
2. Earthing and Safety: Connect the neutral and earth bars according to EWA regulations. Use separate insulators for neutral bars and ensure proper earthing continuity .
3. Cable Management: Use cable trays, conduits, or trunking as per the regulations. Maintain segregation of conductors and avoid overcrowding to prevent overheating .
4. Circuit Segregation: Separate power and lighting circuits using dedicated MCBs and ELCBs. Ensure proper labeling for easy identification and maintenance .
5. Testing and Inspection: After installation, perform insulation resistance tests, continuity checks, and verify correct operation of MCBs and ELCBs. EWA may require inspection before energizing the system .

Licensing and Approval

Before installation, submit an application for electrical equipment licensing to the EWA Customer Care Building in Um Al Hassam, including all required documentation and certifications . Approval must be obtained before energizing the distribution box. Any missing or non-compliant documents will require resubmission.

Summary

To install a double-door distribution box in Bahrain:

• Use EWA-approved, licensed equipment.
• Follow EWA electrical installation regulations for mounting, earthing, and wiring.
• Ensure proper circuit protection with MCBs, ELCBs, and bus bars.
• Conduct testing and inspection before energizing.
• Obtain official approval from EWA to comply with legal and safety requirements .
