Service Overview

Our SLD Implementation service covers the practical execution of approved electrical Single Line Diagrams for industrial and commercial installations. The service includes verification of existing electrical arrangements, modification or installation of required electrical components, feeder connections, panel arrangements, protective devices, cables, earthing systems, and associated electrical infrastructure.

The service can be applied to new installations, factory expansion, electrical system upgrading, corrective action following electrical assessment, and modification of existing systems to align actual installations with approved SLD documentation.

Scope of Implementation

• Review of approved Electrical Single Line Diagram
• Verification of existing electrical system against the SLD
• Transformer and generator connection implementation
• HT and LT distribution system implementation
• MDB, SMDB, DB, PFI and other panel implementation
• Incoming and outgoing feeder implementation
• Cable installation and connection
• Protective device installation and modification
• Earthing and bonding implementation
• Correction of identified discrepancies between actual installation and approved SLD

Existing System Verification

Before implementation, the existing electrical installation is reviewed against the approved SLD to identify differences in equipment ratings, feeder arrangements, protective devices, cable sizes, panel connections, earthing arrangements, and other relevant electrical system information.

• Transformer rating and connection verification
• Generator arrangement verification
• Panel and feeder identification
• Circuit breaker and protective device verification
• Cable size and feeder-route verification
• Load distribution verification
• Earthing and ECC arrangement verification
• Identification of undocumented modifications

Electrical Panel and Feeder Implementation

Electrical panels and feeders are installed, modified, or reconfigured according to the approved SLD and engineering requirements. The implementation considers load capacity, protective devices, cable requirements, feeder identification, and safe distribution of electrical power.

• HT panel arrangement
• LT panel arrangement
• MDB and SMDB implementation
• Distribution Board implementation
• PFI panel integration
• Incoming and outgoing feeder connection
• Breaker and protective device arrangement
• Panel and circuit identification

Cable and Protection Implementation

Cable and protective device arrangements are implemented according to approved engineering calculations and drawings. Where modification is required, applicable cable sizing, voltage-drop considerations, protective device ratings, and installation conditions are reviewed before execution.

• Power cable installation and replacement
• Feeder cable modification
• Cable termination and connection
• Circuit breaker installation or replacement
• Protective device rating implementation
• Cable identification and labeling
• Coordination with approved load schedules

Earthing and Bonding Implementation

Earthing and bonding arrangements shown in the approved electrical design are implemented or corrected as required. This may include panel earthing, equipment earthing, ECC connections, transformer and generator grounding, and connection with designated earth pits.

• Panel earthing
• Transformer earthing
• Generator earthing
• Equipment protective earthing
• ECC installation
• Bonding of applicable conductive parts
• Connection with designated earthing pits

Implementation for Corrective Action

Where electrical inspections, audits, or engineering reviews identify discrepancies between the approved SLD and actual installation, corrective implementation can be carried out to address the identified gaps. This may include circuit reconfiguration, panel modification, cable replacement, protective device correction, labeling, or earthing improvements.
