RACO 509 Switch Box

The Hubbell RACO 509 is a gangable steel switch box designed for residential and light commercial wiring. It provides 12.5 cu. in. of capacity for a single device in cut-in or old work installations. Electricians and DIYers use it when adding a switch or receptacle to finished walls.

Capacity and Knockouts

The box measures 3 in. x 2 in. with a 2-1/2 in. depth and supplies four 1/2 in. knockouts for cable entry. Its 12.5 cu. in. volume limits the number of conductors and devices permitted by code. Gangable sides allow combining multiple boxes for additional capacity when required.

Fire Rating and Mounting

This model is acceptable for use in 2-hour fire rated walls when installed correctly. Integral plaster ears and clips secure the box to drywall or plaster without open stud access. It is not suited for new construction where boxes mount directly to studs or for applications requiring larger device counts.

Questions about this item

Should I choose the 12.5 cu in box or a larger capacity for my wiring?

The 12.5 cu in capacity suits typical single-switch installations; select a larger box only if you need more conductor fill space.

What does the 12.5 cu in capacity mean once the box is installed in a wall?

It provides enough internal volume for standard switch wiring while meeting code limits for conductor fill in a single-gang setup.

Which knockout standard does this box use and what conduit sizes does it accept?

Four 1/2 in. knockouts are supplied, accepting 1/2 in. conduit, NMSC, armored, metal-clad or flex cable with proper fittings.
