Thomas & Betts H050-TB – Frequently Asked Questions
1) I need a raintight conduit hub for an outdoor enclosure - is the Thomas & Betts H050-TB the right choice or should I use something else?
The H050-TB is described as a zinc hub for secure conduit-to-enclosure termination with corrosion resistance, but if your spec calls out a raintight or rainproof hub by name, two peers are built and named for that duty: the ABB TC Series universal raintight conduit hub, and the Square D B125 Series bolt-on hub, which is a rainproof design. Pick by what the drawing or the enclosure listing requires for the wet location.
2) What hub should I use instead of the H050-TB when pulling conductors that need throat protection?
Use the American Fittings AH hub, which is an alloy steel insulated throat hub supplied with a locknut. The insulated throat protects conductor insulation as wire is pulled through, which the H050-TB zinc hub does not advertise. The AH is also an alloy steel body rather than zinc, so note the material change if your spec restricts hub material.
3) Is a zinc conduit hub okay for outdoor or damp locations?
Zinc is the body material on the H050-TB, chosen for corrosion resistance, which is why hubs like this get used on outdoor and industrial enclosures. If your spec calls specifically for a raintight or rainproof hub, the ABB TC Series universal raintight hub or the Square D B125 Series bolt-on rainproof hub are the ones called out that way.
4) What does a conduit hub do that a plain locknut and bushing does not?
A hub threads into the enclosure knockout and seals the connection mechanically at one point, instead of relying on a locknut inside and out plus a separate bushing to protect the conductors. The H050-TB is built for that conduit-to-enclosure termination in 1/2 inch. If you want the conductor protection built in, the American Fittings AH alloy steel hub is an insulated throat version that ships with a locknut.
5) What's the closest alternative to the Thomas & Betts H050-TB zinc hub?
The Crouse-Hinds Myers Scru-Tite basic hub is the nearest match in construction, also zinc die-cast. The ABB TC Series is a universal raintight hub with interchangeable parts, and Square D's B125 Series is a bolt-on rather than a threaded hub, so that one changes how it mounts to the enclosure.
6) Is the Square D B125 bolt-on hub a drop-in substitute for a Thomas & Betts H050-TB?
No. The H050-TB is a threaded conduit hub that terminates conduit into the enclosure opening, while the Square D B125 Series is a bolt-on hub, meaning it mounts to the enclosure with fasteners rather than threading into a knockout. It is also a Square D series intended for matching Square D enclosure hub openings. Treat it as a different mounting method, not an interchange.
7) Which conduit hub covers multiple trade sizes instead of buying a separate 1/2 inch part like the H050-TB?
The ABB TC Series hub is described as universal and interchangeable, which is the option to look at if you want one hub family to cover a range of openings rather than stocking a dedicated 1/2 inch part. The Thomas & Betts H050-TB is a single fixed 1/2 inch zinc hub, which is simpler to order when every opening on the job is the same size.
8) My spec sheet calls for a spec-grade hub - does the Thomas & Betts H050-TB satisfy that or do I need a different part?
If the submittal specifically calls out spec-grade, the American Fittings AH hub is the one in the group carrying a spec-grade designation. The Thomas & Betts H050-TB is a professional-grade zinc hub for conduit-to-enclosure termination; where an engineer has written spec-grade into the drawing, match the wording with the AH rather than arguing the equivalence in the field.
9) Can I standardize on one hub across panels, pull boxes and junction boxes in a facility?
For every 1/2 inch threaded knockout, yes. The H050-TB is a 1/2 inch hub used for panel connections, industrial conduit systems and MRO work, so a facility running 1/2 inch branch conduit can stock this single part number. Boxes with larger knockouts will need the matching size.
10) Is there more than one version of the Thomas & Betts 1/2 inch zinc hub to choose from?
One part number covers it: H050-TB. No finish or configuration choice to make, so there is nothing extra to specify on the order beyond quantity.
