Topaz Lighting 631TBS – Frequently Asked Questions

1) What size flexible metal conduit does the Topaz 630TBS top-bite saddle connector fit?
The Topaz top-bite saddle connectors run seven trade sizes: 3/8, 1/2, 3/4, 1, 1-1/4, 1-1/2 and 2 inch, ordered as 630TBS through 636TBS. Match the trade size to the FMC or AC you are terminating, so 1/2 inch flex takes the 631TBS and 3/4 inch takes the 632TBS. The saddle clamp grips the convolutions of the conduit, so the size has to be right or the clamp will not seat.
2) Do I need a separate locknut and bushing with the Topaz TBS flex connector?
No extra locknut and no anti-short bushing to buy. Each top-bite saddle connector ships with a steel locknut and steel clamps, and the throat is insulated from the factory to keep the conductors off the cut edge of the armor as they enter the box. One piece, so there is nothing to lose out of the pouch on a ladder.
3) Will a top-bite saddle connector thread into a standard knockout on a panel or junction box?
Yes. The male thread is NPSM, the straight machine thread used on box and enclosure hubs, and the connector is secured through the knockout with the included steel locknut. That covers panelboards, load centers and junction boxes at the matching trade size.
4) Are Topaz TBS flex connectors sold individually or in a box?
They come 100 to a pack. That is a contractor quantity, sized for a full rough-in rather than a single repair, so a service tech buying for one device box will end up with a lot of spares.
5) Is a zinc-plated steel flex connector ok for a damp or industrial location?
The body is high-strength steel with a zinc-plated finish, which gives corrosion resistance for commercial and industrial interiors. It is a plated steel fitting, not a raintight or wet-location one, so keep it to dry and protected applications and use a listed raintight connector where water can reach the termination.
6) I am running healthcare branch circuits, does the insulated throat satisfy the anti-short requirement at the box?
The insulated throat is built into the connector and protects conductor insulation from abrasion where it passes into the box, which is the point of an anti-short at an armored cable termination. Topaz lists these for MCAP/MCI-A and MCI-A HCF cables, the HCF designation being the healthcare facility cable type. Standardizing one fitting across a hospital retrofit keeps the terminations consistent for the inspector.
7) What is the part number for a 1 inch Topaz top-bite saddle FMC connector?
1 inch is 633TBS. Stepping either side of it, 3/4 inch is 632TBS and 1-1/4 inch is 634TBS. The numbering runs sequentially from 630TBS at 3/8 inch up to 636TBS at 2 inch, which makes it easy to spec a mixed order off a takeoff.
