Topaz Lighting 750 – Frequently Asked Questions

1) Will the Topaz 743 service entrance cap thread onto rigid conduit, or does it need a clamp?
It threads on. The Topaz 743 service entrance cap uses a threaded connection, so it screws directly onto threaded conduit without a clamp, set screw, or any special tool. If your riser is unthreaded (plain-end PVC or EMT), you need a clamp-type or slip-fit entrance cap instead, or a threaded adapter on the conduit end.
2) Is the Topaz 743 entrance cap UL Listed for a code inspection?
Yes, the Topaz threaded aluminum service entrance cap is UL Listed, which is what an inspector will look for on a service entrance termination.
3) Is an aluminum service entrance cap OK outdoors on a weatherhead riser?
That is exactly what it is built for. The Topaz cap body is corrosion-resistant aluminum, and mounted on conduit it forms a water-resistant cap that keeps moisture off the service entrance conductors. Typical use is outdoor riser terminations on residential, commercial, and industrial services, including utility and metering connections.
4) How many conductors can go through the Topaz service entrance cap?
The cap head has multiple holes in a variety of sizes rather than one opening, so a single cap handles several conductor configurations, including the neutral and the ungrounded conductors of a typical service drop. Hole count and size vary with trade size, so pick the cap matching your conduit and conductor set.
5) Can I use this cap on PVC service entrance conduit?
Only if the PVC riser terminates in a threaded fitting or male adapter, since the Topaz cap is a threaded-connection part. It threads to a male thread; it does not solvent-weld to plain PVC. On a rigid metal riser it threads straight onto the conduit end.
6) Does the Topaz 743 come individually or do I have to buy a box?
Pack size on the Topaz service entrance cap is 100 units.
