The APPLETON 323-R is a threaded reducing bushing designed to adapt a larger conduit knockout or fitting to a smaller conduit trade size. Specifically sized to reduce a 1 inch opening to accept 1/2 inch conduit or fittings, this bushing is a standard electrical fitting used during conduit installation and panel work. Licensed electricians and conduit installers use reducing bushings to make knockout-size transitions without replacing enclosures or conduit bodies. Lightweight at 0.15 pounds, the 323-R is a compact fitting suited for everyday electrical rough-in and finish work.
This reducing bushing is used in residential, commercial, and light industrial electrical installations wherever a conduit knockout or threaded hub needs to be stepped down in trade size. It fits standard applications where a 1 inch threaded entry must accept 1/2 inch conduit or a 1/2 inch threaded fitting, including junction boxes, enclosures, conduit bodies, and panel knockouts.
Designed as an OEM-style replacement and standard conduit fitting for use with 1 inch threaded knockouts and enclosures requiring a 1/2 inch conduit trade size transition.
Installation is performed by licensed electricians in accordance with the National Electrical Code (NEC). De-energize all circuits and lock out power before working inside any enclosure or panel. Use an appropriate conduit wrench or strap wrench to thread the bushing securely into the knockout without over-tightening. Inspect threads on both the bushing and the mating fitting before installation to ensure a clean, secure connection.
