Main Distribution Board (MDB) CAD Detail

If you’re preparing electrical shop drawings or coordination plans, this Main Distribution Board (MDB) CAD detail gives you a clear, ready-to-use panel layout. It includes the front view, internal layout view, and side view, so you can show both the external appearance and the equipment arrangement inside the enclosure.

What you get in this MDB drawing

• Front view with typical meter/indicator positions and feeder arrangement

• Internal (infront) view showing device placement inside the cabinet (breakers/busbar area and wiring space)

• Side view with cabinet depth and ventilation/louver detail

• Overall dimensions to help you plan space in the electrical room and coordinate with architectural walls/clearances

Where this detail helps

• Electrical room layouts and coordination with architects/MEP

• Shop drawings and panel schedules (as a standard template)

• Space planning for maintenance access and panel door swing

• Consistent presentation for project documentation sets

Tip: When you place this MDB in your project, add your project-specific labels such as incoming rating, busbar rating, feeder names, breaker sizes, and panel tag (MDB-01).
