RACO 3008 Grounding Connector

The RACO 3008 is a steel set-screw connector designed for 2-inch IMC and rigid metal conduit. It provides a secure mechanical connection and grounding path for electrical installations in commercial and industrial environments. The zinc-plated finish offers corrosion resistance for long-term durability. UL 514B listing confirms compliance with safety standards for conduit fittings.

Sustained Load Performance

The connector maintains a reliable grounding bond and mechanical grip under continuous vibration and thermal cycling typical of rigid conduit runs. Its concrete-tight rating ensures the connection remains intact when embedded in poured concrete. The set-screw design resists loosening over time without requiring periodic re-torquing. Steel construction withstands physical stress during wire pulling and system expansion.

Deciding Specification

The trade size of 2 inches and compatibility with IMC and RMC conduit types determine if this fitting matches the raceway system. The male NPS thread and set-screw connection method must align with the installation requirements. Buyers needing a different conduit size, compression coupling, or insulated throat cannot use this part.

Questions about this item

How much heat does the RACO 3008 generate during continuous operation?

This grounding connector is a passive steel fitting with no electrical load, so it produces no measurable heat while installed.

What conduit and tools are required to install the RACO 3008?

You need 2 in IMC or RMC conduit, a compatible set-screw driver or wrench, and standard conduit-cutting tools for unthreaded rigid metal conduit.

Will the RACO 3008 connect to older rigid conduit already in the walls?

Yes, it fits 2 in trade-size IMC and RMC, including unthreaded RMC, and its NPS male threads match legacy conduit of the same trade size.
