I need a clean, professional three-line diagram for a commercial distribution board that will use a 600 A main breaker feeding two 400 A MCCB outgoing ways. The drawing must be suitable for consultant review and contractor installation, so accuracy and proper notation are critical. Please integrate metering and monitoring points for the incomer and both feeders, showing CT placement, meter wiring and any auxiliary contacts clearly. Conform to standard commercial practices for breaker symbols, cable sizing notation, earthing and protective device labelling. I will supply the basic load schedule; you return: • A CAD source file (AutoCAD or compatible) • A high-resolution PDF ready for submittal • A brief legend explaining any non-standard symbols used If you normally cross-check with tools such as ETAP or similar, note that in your bid—while not mandatory, it is appreciated for verification. I am looking to approve the final drawing within three days of receipt, so let me know your earliest delivery.

Hi, I went through your project carefully, and the core challenge is clear: creating an accurate and professional three-line diagram for a commercial distribution board that meets precise specifications. This isn’t a surface-level task , it needs someone who understands CAD design and the nuances of electrical engineering and can execute without hand-holding. I’ve handled similar work where precision, speed, and clean execution mattered. My approach is straightforward: I'll utilize AutoCAD to develop the diagram, integrating metering and monitoring points as required while adhering to standard commercial practices for symbols and labels. No guesswork, no bloated process, just results that hold up when reviewed or scaled. If this aligns, I can start immediately and deliver the CAD source file along with a high-resolution PDF in three days. One quick question before I proceed: What is the load schedule you mentioned?

I can prepare a clear, accurate three-line diagram for your commercial distribution board, showing a 600 A main incomer feeding two 400 A MCCB outgoing feeders, fully suitable for consultant review and contractor installation. I have experience producing permit- and construction-ready electrical schematics for commercial LV systems, with careful attention to correct breaker symbols, cable sizing notation, protection labeling, earthing arrangements, and standard industry conventions. For this drawing, I will clearly integrate metering and monitoring on the incomer and both feeders, including CT placement, meter wiring, and auxiliary contacts, all laid out for straightforward interpretation on site. The drawing will be developed in AutoCAD (or compatible CAD format) and delivered with a high-resolution PDF ready for formal submittal, along with a concise legend explaining any non-standard symbols used. Where appropriate, I typically cross-check protection and metering logic against calculation tools such as ETAP or equivalent to ensure consistency and correctness, even when full coordination studies are not required. I can deliver the initial completed drawing quickly and am comfortable working to your three-day approval window. My goal is to provide a precise, professional diagram that reviewers can approve without clarification and contractors can install without ambiguity.
