Thomas & Betts 35B – Frequently Asked Questions

1) What voltage can the Thomas & Betts Marrette No 35 wire connector be used on?
The Marrette No 35 (model 35B) is rated 600V, which covers standard 120/208/240/277/480V building branch circuits and fixture whips. For anything above 600V it is the wrong connector.
2) Can the Marrette 35B twist-on connector be used in a high-temperature fixture or attic junction box?
Yes. The 35B carries a temperature rating of 302 F (150 C), so it holds up in recessed fixture junction boxes, hot attics, and heat-trace or luminaire splices where a 105 C connector would not be accepted.
3) Is the Thomas & Betts Marrette No 35 UL listed and CSA certified for use in Canada?
Both. The 35B is covered under UL E9809 and CSA 6591, so it is acceptable for inspected work on either side of the border. That matters for MRO and institutional buyers standardizing one connector across US and Canadian facilities.
4) Do I need a crimp tool or set screw for the Marrette 35B, or does it just twist on?
It is a twist-on connector, so no tool and no set screw. Strip the conductors, hold them even, and thread the cap on clockwise until the wires twist together inside the insulated shell. No tape or crimp sleeve is required to finish the splice.
5) What is the black cap on a Marrette connector for, and how do I keep sizes straight on the job?
Marrette uses cap color to identify the wire-size range, and the No 35 is the black one. If your crew is already pulling black Marrettes out of the bin, the 35B is the matching reorder. Mixing colors on a job is how the wrong range ends up on a splice, so keep the black caps for the connections the black cap covers.
6) Is the Thomas & Betts 35B sold as a box of 25 or as single connectors?
The 35B is the Marrette No 35 in a 25-count box, and the selling unit of measure is each, meaning one order quantity gets you one box of 25 connectors rather than 25 line items.
7) What is the Marrette 35B shell made of, and will it crack in a cold or damp box?
The shell is a thermoplastic polymer, insulated and one piece, which is what carries the 600V and 150 C ratings. It is not a ceramic or metal-cap connector, so it will not shatter if a box cover pinches it, but like all twist-on connectors it is for dry and damp locations inside an enclosure, not direct burial.
