Thomas & Betts 333D – Frequently Asked Questions
1) What wire sizes does the Thomas & Betts 333D yellow wire connector handle?
The 333D is rated for No. 18 through No. 10 AWG conductors, which covers the usual 14 and 12 AWG branch circuit combinations plus 18 and 16 AWG fixture leads. If your splice falls outside that range, step to a different connector size rather than forcing it.
2) Is the 333D a winged wire nut or a smooth twist-on?
Smooth barrel, no wings. The 333D is a non-winged twist-on connector, so it goes on with fingers or a nut driver socket rather than the leverage a winged version gives you. For overhead work or high-count boxes where installers want extra torque by hand, a winged connector is the easier choice.
3) What is the yellow color on this wire nut supposed to indicate?
Yellow is the shell color of the 333D, and on twist-on connectors color is the trade shorthand for the wire-size range. On this one yellow corresponds to No. 18 to No. 10 AWG. If your crew standardizes by color on a job, that is the range they are picking up when they reach for yellow.
4) What is the shell of the 333D connector made from, and does that matter for where I use it?
The shell is polypropylene. That is a rigid insulating body with a metal spring inside doing the clamping, and it is the standard material for interior branch-circuit splicing in boxes and fixture canopies. It is not a potted or gel-filled connector, so for direct-burial or submerged splices you want a waterproof connector instead.
5) Can I use the 333D for a ground splice or a pigtail in a device box?
Yes, within its conductor range. As a twist-on connector rated No. 18 to No. 10 AWG, it handles the usual pigtail work, hot, neutral, or equipment ground, in device and junction boxes, and the UL E9809 listing covers it for that use. What it will not do is take conductors heavier than No. 10.
6) How is the Thomas & Betts 333D sold, in bulk or individually?
The 333D is sold each as the selling unit of measure, and this configuration is packaged 100 to the pack. For MRO cribs and electrical contractors restocking a van, that is the count you are ordering against.
