Catamount TNF10-250MD-XV – Frequently Asked Questions

1) What wire size does the Catamount TNF10-250MD-XV male disconnect accept?
The TNF10-250MD-XV takes 12-10 AWG stranded conductors, and the yellow nylon insulation is the standard color code for that range. If you are terminating 16-14 AWG you need the blue-coded version instead, and 22-18 AWG uses red.
2) Is this Catamount male disconnect UL Listed for panel and control cabinet wiring?
Yes, it carries UL Listing under file UL E9809, which is what inspectors look for on terminations inside electrical panels, control cabinets, and equipment wiring.
3) What crimp tool do I need for the Catamount TNF10-250MD-XV?
Catamount specifies the WT112M and CM2000A application tools for this disconnect. It is a fully insulated barrel with a metal insulation sleeve, so use the insulated-terminal nest sized for the 12-10 AWG (yellow) range, not a bare-terminal die.
4) Is a brass terminal with a copper sleeve good enough for a vibration-prone equipment install?
The terminal body is brass with a copper sleeve, and the barrel has internal serrations plus a metal insulation sleeve under the nylon. The serrations bite the strands for pull-out resistance and the metal sleeve crimps down on the insulation, which is what keeps the conductor from flexing at the barrel mouth on vibrating equipment.
5) Fully insulated versus non-insulated male disconnect: which should I be using?
The TNF10-250MD-XV is fully insulated, with a molded nylon insulator covering the barrel and the back of the tab. That is the one you want in a crowded panel or cabinet where adjacent terminals or a metal enclosure wall could contact the crimp. Non-insulated versions are for use under a separate sleeve or inside a connector housing that provides the insulation.
6) How many male disconnects come in a pack of the TNF10-250MD-XV?
One pack is 100 pieces. Catamount's own carton structure is 75 inner and 900 outer, so if you are standardizing a harness shop or a panel build, order by the 100-piece pack and plan quantities around that.
7) What is the exact part number to order this yellow 250 Series male disconnect?
Order Catamount part TNF10-250MD-XV. That is the single model on offer: 250 Series male, 12-10 AWG, yellow nylon, 100-piece pack.
