- Always disconnect power at the main service panel before working on electrical equipment. Failure to do so can result in serious injury or death.
- Суурилуулалтын явцад орон нутгийн болон үндэсний цахилгааны бүх дүрмийг дагаж мөрдсөн эсэхийг шалгаарай.
- Хэрэв энэ төхөөрөмж эвдэрсэн гэж үзвэл бүү ашигла.
- Verify the circuit breaker rating matches the circuit requirements.
3. Тохиргоо ба суурилуулалт
The QO2020 circuit breaker is designed for plug-in mounting in Square D QO series load centers. Follow these steps for proper installation:
- Эрчим хүчийг салгах: Turn off the main power supply to the load center at the utility service entrance. Verify power is off using a voltage шалгагч.
- Load Center Access: Remove the cover of the Square D QO load center.
