Although different manufacturers' conduit bodies may look the same, not all are suitable for 'approved' installations. Specific National Electrical Code (NEC) requirements determine which conduit bodies may contain splices, taps, or devices.

Conduit bodies provide access to the conduit system through a removable cover at a junction of two or more entries. Bodies may be used for changing the direction of the wiring systems, to aid in pulling of long wire runs, or to mount devices or make splices.

Underwriters Laboratories (UL) can 'list' conduit bodies as a fitting, which is tested under specification UL514B, however, a fitting cannot contain a device or splice, UL can also 'list' the conduit body as a box tested under specification UL514A. Only the conduit body listed as a box is suitable for use with a device, splices, or taps.

Conduit bodies listed for use with splices, taps, or devices must be marked with the cubic inch volume and any special installation requirements, such as the use of wire pulling compound. The conduit body may also be marked with the maximum wire capacity if the body does not meet the NEC end stop to end stop dimensional requirement for wire pulling: 8 times the trade size for straight pulls, 6 times the trade size for angled pulls.

Always use Bridgeport's UL listed Conduit Bodies
