Thomas & Betts H050A – Frequently Asked Questions
1) What sizes does the Thomas & Betts aluminum hub connector come in, and what are the part numbers?
Two trade sizes: 1/2 inch (MPN H050A) and 3/4 inch (MPN H075A). Both are the same straight aluminum hub connector, so you order by the trade size of the flexible metallic hose or conduit run you are terminating.
2) Is the thread on this Thomas & Betts hub connector NPT or straight machine thread?
It is NPT, the tapered pipe thread used on standard electrical conduit and enclosure hubs. That means it threads into an NPT-tapped hub or boss of matching trade size and pulls up tight for a mechanical, current-carrying joint. If your enclosure opening is an unthreaded knockout rather than a tapped hub, you need a locknut-and-bushing type connector instead.
3) Is this Thomas & Betts hub connector UL listed and CSA approved for inspection?
Yes. It carries UL listing under file E23018 and is CSA listed, which is what an inspector or a spec writer on an institutional job is looking for on a metallic hose fitting.
4) What is this hub connector actually used for on the job?
It is a screw connection for protective metallic hose, meaning it terminates flexible metallic hose or conduit into a threaded housing or enclosure hub. The connection to the housing is by thread, so the fitting does the mechanical hold and maintains the bonding path at the same time. Typical uses are motor and equipment whip terminations in commercial and industrial conduit systems.
5) Will an aluminum hub connector hold up in a damp or corrosive area?
The body is aluminum, which resists corrosion well in normal indoor, outdoor, and industrial atmospheres. Where aluminum is usually avoided is in direct contact with concrete, masonry, or in chemically aggressive wash-down areas; for those specify a steel or malleable iron fitting with a protective coating. Also watch dissimilar metal contact if the enclosure hub is steel.
