Thomas & Betts 5259 – Frequently Asked Questions

1) Is the 5259 insulated or non-insulated, and does that matter for my pull?
It is a non-insulated throat. With no insulating liner at the opening, large conductors can bear on the metal edge, so if your job or spec calls for an insulated throat on 3 inch runs, you want the insulated version of the fitting instead. The non-insulated body gives direct metal-to-metal continuity, which is what you want where the conduit is part of the grounding and bonding path.
2) Should I use a 90 degree liquidtight connector or a straight one with a conduit sweep?
A 90 degree connector like the 5259 makes the turn right at the box or enclosure, which is what you use when there is no room to sweep 3 inch liquidtight into a straight fitting. If you have clearance, a straight connector plus a gradual bend in the conduit keeps pulling tension lower on a long run. Tight-radius 90s at the enclosure are mainly a space decision.
3) Is a malleable iron liquidtight connector OK for a wet or outdoor location?
The 5259 is built of malleable iron and seals liquidtight against moisture and contaminant ingress, and it is used on outdoor electrical enclosures and industrial installations. For continuous chemical or salt exposure, many specs instead call for a nonmetallic or stainless fitting, so check what your drawing specifies for the environment.
4) Do I need a separate bonding jumper with this connector?
The 5259 is non-insulated and gives direct electrical continuity, so the fitting itself carries metal-to-metal contact between the conduit and the enclosure. Whether a supplemental bonding jumper is required depends on your circuit and the length of the flex run, which is a code call on your installation, not a property of the fitting.
5) Will the 5259 provide strain relief for a cord or cable, or just the conduit?
It is a strain relief connector, so the gland clamps the liquidtight jacket and keeps mechanical stress and vibration off the termination inside the box. That is the reason it gets used on equipment connections in manufacturing plants where the conduit moves.
