Panels SLD

Project Overview

Panels SLD (Single Line Diagram)
At Just Energy Incorporation, we specialize in the design, development, and execution of Single Line Diagrams (SLDs) for all types of electrical panels — including LT Panels, DBs, MCCs, and Control Panels. A well-drafted SLD is the foundation of a reliable electrical system, ensuring safety, functionality, and ease of maintenance.

What is an SLD?

A Single Line Diagram (SLD) is a simplified electrical schematic that represents the electrical distribution system using single lines and standardized symbols. It illustrates how electrical power flows from the source (like transformer or utility supply) to final loads, through different panels, circuit breakers, and protective devices.

Our SLD Services Cover:

• Main LT Panel Design

• Distribution Board (DB) Layout

• Sub-Panels and Control Panels

• UPS & Emergency Power Integration

• Load Segregation: Essential vs. Non-Essential

• Transformer & Generator Synchronization

• Cable Sizing & Protection Device Selection

• Power & Lighting Circuit Mapping

Sample SLD Features:

• Incoming Power Source: Grid / Generator / Transformer

• Busbar Layout & Rating

• Main Breakers & Metering Points

• Outgoing Feeders to Sub-DBs

• Protective Devices: MCBs, MCCBs, ELCBs, ACBs

• Load Classification: Lighting, HVAC, Pumps, IT, etc.

• Earthing & Neutral Distribution

• Spare Provisions for Future Expansion

Standards & Best Practices:

• Drawn using IEC/IS/ANSI-compliant symbols

• Designed using software like AutoCAD, EPLAN, or ETAP

• Complies with standards: IS 8623, IEC 61439, IS 3043

• Calculated for voltage drop, fault levels, short-circuit capacity
