Installation of electricity meter distribution boxes in Bahrain

Electricity meter distribution boxes in Bahrain must be installed according to EWA regulations, approved electrical standards, and with proper documentation and municipal approvals.

Regulatory Requirements

In Bahrain, the installation of electricity meters and distribution boxes is governed by the Electricity and Water Authority (EWA) and the Bahrain Electrical Installation Regulations. All installations must comply with the EDD (Electricity Distribution Directorate) regulations, which include requirements for wiring, earthing, distribution boards, and safety devices such as circuit breakers and earth leakage protection. Any deviation from these regulations requires prior approval from the EDD.

Documentation and Approvals

Before installation, the following documents are typically required: Completed Electricity Technical Services Request FormAerial map and survey certificate of the propertyFor tenants: lease contract and no-objection letter from the property ownerCertificate of completion and proof of inspection of electrical installationsNo Objection Letter from the municipality for connecting the property to the electricity grid These documents ensure that the installation is legally compliant and safe for connection to the national grid.

Technical Standards

Distribution boxes and meter installations must adhere to the following technical standards: Distribution boards must be properly rated for the load and include protection devices such as MCBs and RCDs. Wiring and cabling should follow the approved methods, including PVC-insulated copper cables, conduits, trunking, and busbar arrangements. Earthing and bonding must comply with EWA requirements to prevent electric shock and ensure system safety.

Schematic drawings showing cable sizes, switchgear positions, prospective short-circuit currents, and maximum demand values must be displayed near the distribution board. Fireman's switch and other safety devices should be installed where required.

Installation Process

Site Preparation: Ensure the premises are ready, with proper conduits, cable trays, and mounting points for the distribution box. Meter Box Installation: Install the meter box at an accessible location, typically outside the building or in a designated meter room. Wiring and Connections: Connect the main supply to the distribution board, ensuring correct phase, neutral, and earth connections.

Inspection and Testing: Conduct electrical tests, including insulation resistance, continuity, and earth loop impedance, to verify compliance with EWA standards. Activation: Submit the installation for EWA inspection. Once approved, the meter is activated, and electricity supply is connected.
