Carlon SN-21-DV – Frequently Asked Questions

1) What is a dual voltage outlet box like the Carlon SN-21-DV used for?
It's a single-gang non-metallic box with an internal divider so line voltage and low voltage land at the same opening without sharing a compartment. Typical use is a TV or workstation location where you want a receptacle on one side and data, coax or speaker wire on the other. Carlon lists it as a dual voltage outlet box/bracket.
2) How much wire volume does the Carlon SN-21-DV box give me for box fill calculations?
The stated volume is 20.5 cubic inches. Carlon markets it as a 21 cubic inch box, but use the 20.5 figure when you run your conductor fill count, since that is the spec value on record.
3) Does the Carlon SN-21-DV box have knockouts for conduit?
No. The knockout count on this box is zero, so it is not set up for conduit or NM connectors through pre-punched openings. It is built for standard non-metallic cable entry through the box's own cable entry points, not for pipe. If you need conduit entries on a single-gang plastic box, specify a knockout-style PVC box instead.
4) Can I run cable TV and a receptacle out of the same box legally?
Only where the two systems are physically separated by a permanent barrier, which is exactly what this Carlon dual voltage box provides. The divided design keeps low voltage conductors out of the line voltage compartment in one mounting location. The box itself is UL listed under file E11461.
5) Is a PVC box like this okay in a damp or corrosive area?
The SN-21-DV is molded PVC with no metal shell, so there's nothing to rust the way a steel box does. That said, it is a standard non-metallic device box, not a weatherproof or in-use enclosure, so keep it to dry interior walls and use a listed weatherproof box outdoors.
6) What part number do I order for the Carlon 21 cubic inch dual voltage box, and where is it made?
Order Carlon part SN-21-DV. It's sold under the Carlon / Nutek brand label and made in the United States.
7) Will a standard single gang wall plate and device fit this box?
Yes, it's a single-gang box, so it takes standard single-gang devices and cover plates on the power side. Plan the low voltage side around a plate or insert that suits the jacks you're terminating, since both sides share the one opening.
8) Why is the Carlon SN-21-DV blue, and does the color mean anything on the job?
Blue is Carlon's standard color for its non-metallic boxes and it makes the dual voltage box easy to spot during rough-in and inspection. The color has no bearing on rating or capacity, it's identification only.
