    Product FAQs

    5 answers
    Which Square D panelboards accept the QOB2125SL?

    This bolt-on device is compatible with Square D NQ and NQOD series panelboards. It cannot be installed in standard QO load centers, which require plug-on connections.

    What does the SL suffix indicate in the QOB2125SL catalog number?

    The SL suffix indicates that this unit functions as a Sub-feed Lug device. It is typically used to tap off the main panelboard bus to supply power to a secondary sub-panel or remote load.

    How many panel spaces are required to install this 2-pole device?

    The QOB2125SL requires two standard spaces in a compatible Square D panelboard.

    What are the wiring requirements for the QOB2125SL lugs?

    The lugs accept AWG 12 through AWG 2/0 copper or aluminum conductors. When terminating the wires, ensure you use the correct torque values specified by the manufacturer to prevent thermal issues under load.

    How is the QOB2125SL secured to the panelboard bus?

    This device utilizes a bolt-on connection, requiring it to be mechanically fastened to the panelboard bus with screws. This provides a secure, vibration-resistant connection typical in commercial and industrial applications.
