3. ຜະລິດຕະພັນເກີນview
The BRYANT BD20/20 is a 2-pole, 20-amp circuit breaker designed for 120/240V applications. It features a 10,000 Ampere Interrupting Capacity (AIC), indicating its ability to safely interrupt high fault currents. The breaker is designed for plug-in mounting in compatible load centers.
This image displays the front of the BRYANT BD20/20 circuit breaker. It clearly shows the two red toggle switches, labeled "ON" and "OFF" for each pole. The brand "BRYANT" and model "BD20-20" are visible, along with "CU-AL SWD" indicating compatibility with copper and aluminum wiring. The UL listing information is also present at the top.
This image shows the bottom side of the BRYANT BD20/20 circuit breaker. Visible markings include "USE ONLY IN LISTED ENCLOSURE", "40 C CPL 60/75 C WIRE", and several patent numbers. The text "MADE IN U.S.A." is also clearly visible, indicating the country of manufacture.
This image displays the top side of the BRYANT BD20/20 circuit breaker. Key information includes the "TORQUE" specifications for wire connections: 14-10 AWG 20 IN.LBS., 8 AWG 25 IN.LBS., and 6-4 AWG 27 IN.LBS. The "CURRENT INTERRUPTING RATING" is also shown as "MAX. RMS SYM. AMPERES 10,000 AT 120/240 VOLTS AC".
4. ການຕິດຕັ້ງແລະການຕິດຕັ້ງ
ສຳຄັນ: Ensure all power to the electrical panel is OFF before proceeding with installation. Use a voltage tester to confirm the absence of power.
- ການຕັດການເຊື່ອມຕໍ່ໄຟຟ້າ: Locate the main service panel and turn off the main breaker to completely de-energize the panel.
- ການເຂົ້າເຖິງແຜງ: Carefully remove the cover of the electrical panel to expose the bus bar and wiring.
- ການຈັດວາງ Breaker: Identify an available slot on the bus bar that is compatible with the BD20/20's plug-in design.
- ການຕິດຕັ້ງ: Align the circuit breaker with the bus bar and firmly push it into place until it clicks securely. Ensure both poles are properly seated.
- ສາຍໄຟ: 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).
- ການເຊື່ອມຕໍ່ທີ່ປອດໄພ: Tighten the terminal screws to the specified torque to ensure a secure and safe electrical connection.
- ການປະກອບກະດານຄືນ: Replace the electrical panel cover, ensuring all screws are tightened.
- ການຟື້ນຟູພະລັງງານ: Turn the main breaker back ON at the service panel.
- ການທົດສອບ: Test the circuit protected by the newly installed breaker to confirm proper operation.
5. ຄໍາແນະນໍາການດໍາເນີນງານ
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.
- ເພື່ອເປີດ: Push the red toggle(s) firmly to the "ON" position.
- ເພື່ອປິດ: 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. ບໍາລຸງຮັກສາ
Circuit breakers like the BRYANT BD20/20 are generally maintenance-free. However, periodic visual inspection is recommended.
- ການກວດກາປະຈຳປີ: 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).
- ທໍາຄວາມສະອາດ: 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.
- ການທົດສອບ: While not typically required for residential breakers, some commercial or industrial applications may require periodic testing by a qualified professional.
