Square D SN0310 Neutral Block Safety Switch Accessory

Product Description

The SQUARE D SN0310 is a neutral block accessory designed for use with compatible Square D safety switches. It provides a dedicated neutral termination point within the switch enclosure, allowing electricians to properly land neutral conductors in compliance with NEC requirements. The SN0310 measures 7.1 inches in length, 6.3 inches in width, and 3.8 inches in height, making it sized for direct integration into the switch assembly. This accessory is installed by licensed electricians during new construction or service upgrades where a switched neutral or bonded neutral point is required in the disconnect.

The SN0310 neutral block is suited for residential and light commercial electrical service applications where Square D safety switches are deployed as the primary disconnecting means. It is typically installed in situations requiring a separate neutral bus within the disconnect enclosure, such as when running branch circuits or service entrance conductors through a fusible or non-fusible safety switch.

• Compact form factor at 7.1 x 6.3 x 3.8 inches for direct-fit installation

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lockout/tagout the safety switch and all upstream power sources before beginning work. Verify that the neutral block mounting location inside the enclosure is clear and that conductor sizing is appropriate for the terminations. Do not install the neutral block with the switch energized.
