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. সেটআপ এবং ইনস্টলেশন
গুরুত্বপূর্ণ: Ensure all power to the electrical panel is OFF before proceeding with installation. Use a voltage tester to confirm the absence of power.
- বিদ্যুৎ সংযোগ বিচ্ছিন্ন: Locate the main service panel and turn off the main breaker to completely de-energize the panel.
- প্যানেল অ্যাক্সেস: Carefully remove the cover of the electrical panel to expose the bus bar and wiring.
- ব্রেকার স্থাপন: Identify an available slot on the bus bar that is compatible with the BD20/20's plug-in design.
- ইনস্টলেশন: Align the circuit breaker with the bus bar and firmly push it into place until it clicks securely. Ensure both poles are properly seated.
- ওয়্যারিং: 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).
- নিরাপদ সংযোগ: Tighten the terminal screws to the specified torque to ensure a secure and safe electrical connection.
- প্যানেল পুনঃসংযোজন: Replace the electrical panel cover, ensuring all screws are tightened.
- শক্তি পুনরুদ্ধার: Turn the main breaker back ON at the service panel.
- পরীক্ষা: Test the circuit protected by the newly installed breaker to confirm proper operation.
5. অপারেটিং নির্দেশাবলী
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.
- চালু করতে: Push the red toggle(s) firmly to the "ON" position.
- বন্ধ করতে: Push the red toggle(s) firmly to the "OFF" position.
- ট্রিপড ব্রেকার রিসেট করতে: 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. রক্ষণাবেক্ষণ
Circuit breakers like the BRYANT BD20/20 are generally maintenance-free. However, periodic visual inspection is recommended.
- বার্ষিক পরিদর্শন: 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).
- পরিষ্কার করা: 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.
- পরীক্ষা: While not typically required for residential breakers, some commercial or industrial applications may require periodic testing by a qualified professional.

|---|---|---|
| ব্রেকার ঘন ঘন ট্রিপ করে। | ওভারলোডেড সার্কিট, শর্ট সার্কিট, অথবা গ্রাউন্ড ফল্ট। | Reduce load on the circuit. Unplug appliances. Inspect wiring for damage. If problem persists, consult a qualified electrician. |
| ব্রেকার রিসেট হয় না। | Persistent fault (short circuit/ground fault) or internal breaker damage. | Ensure the toggle is pushed fully to "OFF" before attempting to reset to "ON". If it still won't reset, do not force it. Call a qualified electrician. |
| ইনস্টলেশনের পরে সার্কিটের কোনও শক্তি নেই। | Breaker not fully seated, loose wiring connections, or main power off. | Verify main breaker is ON. Ensure the BD20/20 is fully seated on the bus bar. Check wire connections for tightness (with power OFF). |
If you are unable to resolve an issue, or if you suspect a serious electrical problem, always contact a qualified and licensed electrician.
