EMT Conduit Body

 

Material	Properties	Common Applications
Aluminum	Lightweight, corrosion-resistant	Residential, commercial, damp locations
Galvanized Steel	Strong, durable, moderate corrosion resistance	Commercial, industrial, rugged use
Malleable Iron	Extremely strong, impact-resistant	Heavy industrial, harsh environments

 

 

Size (Trade)	Actual OD (in.)	Common Use
3/8"	~0.577	Specialized, small-scale
1/2"	~0.706	Residential, light commercial
3/4"	~0.922	Commercial, larger circuits

• Wire Access: The removable cover allows entry to the conduit interior for pulling wires through long runs.
• Directional Changes: Shapes like LB, LR, and LL enable 90° bends, while C types maintain straight runs with acces.
• Branching: T and X types allow conduit to split into multiple directions.
• Wiring Protection: Shields wires at junction points from damage.
• Grounding: As a metallic fitting.
• Code Compliance: Meets NEC 314.5 and 358.42 requirements for accessible splices and pull points in conduit systems.
• Residential:

Used to route 1/2" EMT conduit around corners or split circuits.

• Commercial:

Employed in office buildings, retail spaces, or warehouses.

• Light Industrial:

Applied in workshops or small factories to facilitate wire pulling or directional changes in exposed EMT runs.

• Specific Uses:

Pull Point: Simplifies wire installation in long or complex runs.

Splicing: Houses wire connections or taps within the conduit system.

Directional Adjustment: Replaces sharp conduit bends with smoother transitions.

Maintenance: Allows future access for repairs or upgrades.

 

 

1. EMT Conduit Body Main Body:

Material: Typically die-cast aluminum or galvanized steel.

Design: A hollow, cast enclosure shaped to specific configurations.

2. Hubs:

Material: Same as the body.

Design: Two or more cylindrical extensions with smooth bores to accept EMT conduit.

Set Screws: Threaded holes.

Compression (Alternative): Some designs use compression rings and nuts for a tighter fit.

Configurations vary by type.

3. Removable Cover:

Material: Typically matches the body.

Design: A flat or slightly curved plate, secured with 2-4 screws.

4. Interior Space:

Design: A hollow cavity connecting the hubs, with smooth walls to ease wire pulling and prevent insulation damage.

5. Gasket (Optional):

Material: Rubber, neoprene, or similar elastomers.

Design: A thin, flexible seal fitted between the cover and body.

 

 

• Shape/Type:

LB: 2 hubs, 90° back entry.

LR/LL: 2 hubs, 90° right/left entry.

T: 3 hubs, tee configuration.

C: 2 hubs, straight-through.

X: 4 hubs, cross configuration.

• Size: 1/2" to 4" (trade sizes), with hubs and body scaling.
• Connection: Set-screw or compression hubs.
