Product FAQs
8 answersWhich panelboards are compatible with the BDA36050 circuit breaker?
This breaker mounts directly into Square D I-Line panelboards and switchboards. It uses a shrouded plug-on jaw for the line side bus connection.
What type of load side terminals are provided on this breaker?
The load side features standard mechanical lugs that accept 14 AWG to 2/0 AWG aluminum or copper wire. The line side requires no lugs, as it utilizes the I-Line plug-on connection.
What are the lug tightening torque specifications for the BDA36050?
For 14 AWG to 10 AWG wire, torque the lugs to 31.9 to 38.9 lb-in. For heavier 8 AWG to 2/0 AWG conductors, the required torque is 44.3 to 54.9 lb-in.
Does the BDA36050 include a manual trip feature for testing?
Yes, PowerPacT B-Frame breakers feature an integral push-to-trip button on the front cover. This allows you to manually trip the mechanism to verify proper mechanical operation.
What is the continuous current rating for this 50A breaker?
The BDA36050 is a standard 80 percent rated circuit breaker. Continuous loads should not exceed 40 amps to comply with typical electrical code requirements for standard rated devices.
How do the dual-break rotating contacts benefit electrical systems?
PowerPacT B-Frame breakers utilize a dual-break rotating contact design that limits peak current during a short circuit fault. This clears faults quickly and improves downstream equipment protection.
Does this breaker require a separate mounting kit for I-Line panelboards?
No, the BDA36050 comes factory-equipped with the necessary shrouded I-Line plug-on jaws on the line side. It snaps directly onto the panelboard bus without additional mounting hardware.
Are the thermal and magnetic trip points adjustable on this breaker?
No, the BDA36050 features a fixed thermal-magnetic trip unit. Both the long-time thermal protection and instantaneous magnetic trip functions are permanently set at the factory.
