Match the Fitting to the Wiring Method
Begin with the raceway or cable system, not the fitting. EMT, rigid metal conduit, IMC, flexible raceways, nonmetallic raceways, and flexible cable entries use different product families and listings. The size and fitting type must match the wiring method shown on the product. For EMT-specific products, browse EMT fittings.
Connectors and Couplings Serve Different Connections
A raceway connector typically terminates conduit or tubing at a box, enclosure, or equipment opening, while a coupling joins two compatible raceway sections. Both must be sized and identified for the exact raceway. If a product is described as rain-tight, concrete-tight, wet-location, or otherwise environmentally rated, confirm that rating on the specific item rather than assuming the connection style alone provides it.
Conduit Bodies and Bushings Solve Different Tasks
Conduit bodies provide access for pulling and routing conductors, with the body style determining the path through the raceway. Conduit and grounding bushings protect or support specific raceway-entry and bonding functions. If a conduit body will contain splices or taps, verify that the exact body is marked and suitable for that use.
Cable Glands and Cord Grips Are for Cable Entry
Cable glands and cord grips are selected by both the enclosure hub or thread size and the cable outside-diameter range. They are not substitutes for conduit connectors. Match material, cable range, strain-relief function, and environmental rating to the complete enclosure entry.
Finish the Installation With Compatible Accessories
Check locknuts, sealing components, insulated throats, glands, and bonding hardware as part of the assembly. Raceway fittings do not replace conductor-splicing products; for conductor terminations and splices, use listed wire connectors suitable for the conductor type and size. For broader fitting families, see electrical fittings.
Conduit Fitting FAQs
What is the difference between a coupling and a connector?
A coupling joins compatible raceway sections. A connector terminates a raceway at a box, enclosure, or equipment entry.
Is a cable gland the same as a conduit connector?
No. A cable gland or cord grip is designed around a flexible cable entry, while a conduit connector terminates a raceway.
Is compression always better than set-screw?
No. The correct choice depends on the fitting's listing, raceway type, installation environment, and project requirements.
