Commercial 600A DB Three-Line Design

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.
