Check the model number inside the distribution box

The model number of a distribution box is usually printed on the box itself or on the incoming line circuit breaker inside the panel.

Steps to Locate the Model Number

1. Turn Off Power and Ensure Safety Before opening the distribution box, make sure to turn off the main power supply and wear appropriate safety gear, such as insulated gloves and safety glasses, to prevent electrical hazards .
2. Open the Distribution Box Carefully open the panel door. Inside, you will see the main switch, circuit breakers, bus bars, and labels .
3. Check the Incoming Line or Main Breaker The incoming line part often displays the model number, rated breaking current, and other specifications of the main circuit breaker or the distribution box itself . Look for printed labels, stickers, or engraved markings on the main breaker or near the top of the panel.

   • Model number
   • Serial number
   • Voltage rating
   • Maximum current rating
   • Safety certifications (e.g., IEC or NEC standards)
5. Check Documentation or Diagrams If the label is missing or unclear, refer to the system diagram or installation manual, which often lists the model number and specifications of the distribution box .
6. Consult a Licensed Electrician if Needed If you cannot locate the model number safely, a licensed electrician can help identify it without risking injury or violating electrical codes .
