Installation of the QOB120CP circuit breaker requires knowledge of electrical systems and adherence to safety protocols. It is strongly recommended that installation be performed by a qualified electrician.
Installation Steps (for Qualified Electricians):
- ການຕັດການເຊື່ອມຕໍ່ໄຟຟ້າ: ກວດໃຫ້ແນ່ໃຈວ່າໄຟທັງໝົດໄປຫາແຜງໄຟຟ້າຖືກປິດຢູ່ເມື່ອຕັດການເຊື່ອມຕໍ່ບໍລິການຫຼັກ. ຢືນຢັນດ້ວຍ voltage ເຄື່ອງທົດສອບ.
- ການເຂົ້າເຖິງແຜງ: ເອົາຝາປິດຂອງແຜງໄຟຟ້າອອກຢ່າງລະມັດລະວັງ.
- ການຈັດວາງ Breaker: Identify an available space in the Square D NQ or NQOD panelboard. The QOB120CP is a single-pole breaker and requires one space.
- Bolt-On Connection: Position the circuit breaker onto the bus bar and secure it using the bolt-on mechanism. Ensure a firm and proper connection.
- ສາຍໄຟ: Connect the circuit wire to the load terminal of the breaker. Ensure the wire gauge is appropriate for a 20 Amp circuit. Tighten the terminal screw to the manufacturer's specified torque.
- ການປະກອບກະດານຄືນ: Once all connections are secure and verified, replace the electrical panel cover.

5. ການດໍາເນີນງານ
The QOB120CP circuit breaker operates automatically to protect circuits from overcurrent conditions.
- ເປີດຕຳແໜ່ງ: When the circuit breaker handle is in the "ON" position, power is supplied to the circuit.
- ປິດຕຳແໜ່ງ: Moving the handle to the "OFF" position manually disconnects power to the circuit.
- Tripped Position (Visi-Trip): If an overload or short-circuit occurs, the circuit breaker will automatically trip. The handle will move to a midpoint position between "OFF" and "ON," and a highly visible red indicator will appear, making it easy to identify the tripped breaker.
ຣີເຊັດຕົວເບຣກເກີທີ່ຕິດຄ້າງ:
- ລະບຸສາເຫດ: Before resetting, attempt to identify and correct the cause of the trip (e.g., unplug overloaded appliances).
- ປິດເຕັມ: Firmly push the circuit breaker handle all the way to the "OFF" position. This resets the internal tripping mechanism.
- ເປີດ: Push the handle firmly to the "ON" position. If the breaker immediately trips again, do not attempt to reset it further. Contact a qualified electrician.
6. ບໍາລຸງຮັກສາ
The Square D QOB120CP circuit breaker is designed for reliable, long-term operation and requires minimal maintenance.
- ການກວດກາປົກກະຕິ: Periodically inspect the circuit breaker and electrical panel for any signs of damage, discoloration, or loose connections. This should be done by a qualified electrician.
- ທໍາຄວາມສະອາດ: Keep the area around the electrical panel and circuit breakers clean and free from dust and debris. Do not use liquids for cleaning inside the panel.
- ບໍ່ມີພາກສ່ວນທີ່ຜູ້ໃຊ້ບໍລິການ: This device contains no user-serviceable parts. Do not attempt to disassemble or repair the circuit breaker.
