Topaz Lighting TOP360 – Frequently Asked Questions

1) What size knockout does the Topaz 360 3/8 inch duplex connector fit?
The Topaz 360 is a 3/8 inch trade size connector, and the hub drops into a standard 1/2 inch knockout. It ships with a UL Listed locknut, so you can land it in a panel, junction box, or device box without sourcing the nut separately.
2) Will this Topaz connector work with MC cable, or is it only for BX flex?
It takes BX-FLEX, NM, and MC cable. For aluminum smooth extruded MC, the clamp is sized for an outer diameter of .210 to .500. Measure the jacket OD on your cable; anything outside that window needs a different fitting.
3) Can I use the Topaz 360 clamp connector outdoors or in a wet location?
No. The 360 is rated for interior, dry locations only. For exterior runs, damp basements, or anywhere subject to weather, you need a fitting listed for wet locations instead.
4) Why is it called a duplex connector, and what does that change on the job?
Duplex means the fitting takes two cables through one knockout instead of one. The two-screw clamp assembly grips each cable, so you cut your knockout count in half on a crowded panel or device box. If you only ever run a single cable per opening, a standard single clamp connector does the same job with less hardware.
5) Is the Topaz 360 duplex connector UL Listed?
Yes, it is UL Listed, and the locknut that ships with it is UL Listed as well. That is the piece an inspector or a spec-driven facility buyer usually wants confirmed before the fitting goes in.
6) Does the Topaz 360 thread into a box, or does it need a locknut?
It uses an NPT male hub through the knockout and is secured inside with the included locknut. The threaded hub seats tight at the enclosure wall, so no additional bushing or nut has to be ordered to complete the termination.
7) What is the Topaz 360 connector made of, and will it hold up in a panel that vibrates?
Body is corrosion-resistant zinc die-cast. The two-screw clamp puts pressure on the cable from both screws rather than a single set screw, which keeps the cable from working loose under vibration at the enclosure entry.
8) How many Topaz 360 connectors come in a box?
The 360 is packed 100 per unit, which is how these move for rough-in work where you are landing dozens of cable entries across a job.
