4. Pemasangan
The QOM100VHCP main breaker is designed for field installation in 100-125 Amp convertible QO or Homeline load centers. Ensure the load center is de-energized before proceeding.
Langkah Pemasangan:
- Nyahdayakan Pusat Beban: Turn off the main power supply to the load center at the utility meter or main service disconnect. Verify with a voltage tester that all power is off.
- Buang Komponen Sedia Ada: If replacing an existing main breaker or filler plates, carefully remove them according to the load center's instructions.
- Position the Breaker: Align the QOM100VHCP main breaker with the designated main breaker slots in the load center. The breaker is designed for a plug-on connection to the bus bars.
- Secure the Breaker: Ensure the breaker is firmly seated on the bus bars and secured with any provided mounting hardware (e.g., screws or clips) as per the load center's instructions.
- Sambungan Wayar: Connect the incoming service conductors to the main breaker's lugs. The breaker accepts #4 - 2/0 AWG wire. Strip the wire insulation to the length indicated by the strip gauge on the breaker (typically 3/4 inch). Tighten the lug screws to the torque specifications provided on the breaker or in the load center manual.
- Sahkan Sambungan: Double-check all wire connections for tightness and proper insulation.
- Pulihkan Kuasa: Replace the load center cover. Restore power to the load center.

5. Operasi
The QOM100VHCP main breaker functions as the primary overcurrent protection device for the entire load center. In normal operation, the breaker switch will be in the 'ON' position. If an overload or short circuit occurs, the breaker will automatically trip to the 'OFF' position, interrupting the electrical flow to prevent damage to the electrical system and connected equipment.
Menetapkan Semula Pemutus Tersandung:
- Kenalpasti Punca: Before resetting, attempt to identify and correct the cause of the trip (e.g., unplug overloaded appliances, fix a short circuit).
- MATI sepenuhnya: Move the breaker handle firmly to the full 'OFF' position. You may feel a click.
- HIDUPKAN: Move the breaker handle firmly to the 'ON' position.
- If the breaker immediately trips again, do not attempt to reset it further. Contact a qualified electrician.
6. Penyelenggaraan
Circuit breakers generally require minimal maintenance. Regular visual inspections are recommended.
- Pemeriksaan Tahunan: Periodically inspect the breaker and its connections for any signs of overheating, discoloration, loose wires, or physical damage.
- Pembersihan: Ensure the area around the breaker is free from dust and debris. Do not use liquids for cleaning inside the load center.
- Ujian: While not typically required for residential main breakers, some industrial applications may require periodic testing. Consult a qualified electrician for specific testing requirements.
WARNING: Do not attempt to repair a damaged or malfunctioning breaker. Replace it with an identical or approved equivalent.
