PATAKI: Ensure all power to the electrical panel is OFF before proceeding with installation. Use a voltage tester to confirm the absence of power.
- Ge asopọ agbara: Locate the main service panel and turn off the main breaker to completely de-energize the panel.
- Wiwọle Igbimọ: Fi pẹ̀lẹ́pẹ̀lẹ́ yọ ideri panẹli ina naa kuro lati fi ọpa akero ati awọn okun waya han.
- Ibi Ipilẹṣẹ: Identify an available slot on the bus bar that is compatible with the BD20/20's plug-in design.
- Fifi sori: Align the circuit breaker with the bus bar and firmly push it into place until it clicks securely. Ensure both poles are properly seated.
- Asopọmọra: Connect the circuit wires to the appropriate terminals on the circuit breaker. For the BD20/20, connect the two hot wires to the respective screw terminals. Refer to Figure 3.3 for recommended torque specifications for wire gauges (14-10 AWG: 20 in-lbs, 8 AWG: 25 in-lbs, 6-4 AWG: 27 in-lbs).
- Awọn isopọ to ni aabo: Tighten the terminal screws to the specified torque to ensure a secure and safe electrical connection.
- Àtúntò Pánẹ́lì: Replace the electrical panel cover, ensuring all screws are tightened.
- Imupadabọ agbara: Turn the main breaker back ON at the service panel.
- Idanwo: Test the circuit protected by the newly installed breaker to confirm proper operation.
5. Awọn ilana Iṣiṣẹ
The BRYANT BD20/20 circuit breaker operates with simple ON/OFF toggles. When the circuit breaker trips due to an overload or short circuit, the toggle will move to a central or "tripped" position, typically between ON and OFF.
- Lati Tan: Push the red toggle(s) firmly to the "ON" position.
- Lati PA: Push the red toggle(s) firmly to the "OFF" position.
- To Reset a Tripped Breaker: First, push the toggle(s) completely to the "OFF" position. Then, push the toggle(s) firmly to the "ON" position. If the breaker immediately trips again, there may be a persistent fault in the circuit that requires professional attention.
6. Itọju
Circuit breakers like the BRYANT BD20/20 are generally maintenance-free. However, periodic visual inspection is recommended.
- Ayewo Ọdọọdun: Annually, or as required by local codes, have a qualified electrician inspect the circuit breaker and its connections for any signs of wear, corrosion, or overheating (discoloration).
- Ninu: Ensure the area around the circuit breaker within the panel is free from dust and debris. Do not use liquids for cleaning inside the electrical panel.
- Idanwo: While not typically required for residential breakers, some commercial or industrial applications may require periodic testing by a qualified professional.
