NSi TERMINATOR TM-RY Red/Yellow Premium Wire Connector, 18-8 AWG

NSi TERMINATOR TM-RY Red/Yellow Premium Wire Connectors are UL Listed pressure-type connectors rated for copper wire in the 18-8 AWG wire range, with a 600V voltage rating and 105C temperature rating. The dual red/yellow color coding lets one premium connector do the job of two standard connectors in most applications, and the zinc-plated steel spring delivers secure, low-resistance connections without pre-twisting. This listing is available in multiple package options — 100 pack, 500 pack, and jar — so contractors and electricians can choose the quantity that best fits a job site stock order or a high-volume commercial supply run, all sharing the same connector construction and electrical ratings.

NSi NSITM-RY-100P – Frequently Asked Questions

1) What wire sizes will the NSi TERMINATOR TM-RY twist-on connector take?
The TM-RY handles copper conductors from 18 AWG up to 8 AWG. That range is why the red/yellow dual coding exists: one connector covers the combinations that would otherwise need two separate standard connectors. Copper only, so don't use it on aluminum conductors.
2) Is the TM-RY wire connector rated for 600V commercial work?
Yes, the TERMINATOR TM-RY carries a 600V rating and is UL Listed as a pressure-type wire connector, with cULus listing as well. Temperature rating is 105C, so it holds up in warm panel and fixture locations.
3) Can I use the TM-RY connector on an overhead aluminum service or line tap?
No. The TM-RY is rated for copper wire only and is a twist-on connector for box and enclosure splices. For aluminum line tap work you want a compression connector such as the Burndy YHD Series aluminum compression line tap. Burndy's IMPLO implosive 9 Series and 9052 Series connectors are the other direction for utility-grade conductor splicing.
4) Is the Ideal INSURE 30-1012 a substitute for the NSi TM-RY connector?
They solve the connection differently. The Ideal Industries 30-1012 is an INSURE connector sold in a 90-pack and rated for 12 AWG, so it is aimed at a single conductor size. The NSi TERMINATOR TM-RY is a twist-on pressure-type connector rated across 18-8 AWG copper, with dual red/yellow color coding so one connector covers the combinations that would otherwise take two standard connectors. If your junction boxes mix conductor sizes, the broader-range TM-RY handles more of them from one bin; if you are working strictly in 12 AWG, the Ideal part is size-specific.
5) Can I use a Burndy IMPLO or YHD connector in place of the NSi TM-RY in a junction box?
No - those are a different class of connector. The Burndy 9051 and 9052 are IMPLO implosive-technology connectors, and the Burndy YHD is an aluminum compression line tap. Both families are installed with tooling or an energetic charge on utility-style conductors. The NSi TERMINATOR TM-RY is a hand-installed twist-on pressure-type connector for copper wire only, 18-8 AWG, 600V and 105C rated, with rounded wings for grip and torque during installation. For panelboard and junction box splices, stay with the twist-on connector.
6) I need a connector for aluminum conductors - does the NSi TM-RY work, or should I look at something else?
The NSi TERMINATOR TM-RY is rated for copper wire only, so it is not the part for an aluminum run. Within the comparable connectors, the Burndy YHD series is an aluminum compression line tap connector, which is the family to look at for aluminum conductors. Note that it is a compression connector rather than a twist-on, so it requires the matching crimp tooling and die rather than hand installation.
7) Do I have to pre-twist the wires before putting on a TM-RY connector?
No pre-twisting needed. The TM-RY uses a zinc-plated steel spring with a quick-bite grip that pulls the stripped conductors together as you turn it. The rounded wings give you something to grip and more torque by hand, which matters when you're making a few hundred splices in a day.
8) What pack sizes does the NSi TM-RY come in, and what are the part numbers?
Two order options: TM-RY-100P is the 100 pack, and TM-RY-500J is the 500 count jar. Same connector, same ratings in both, so pick by how much you burn through. The jar suits truck stock and high-volume rough-in; the 100 pack suits a single job or a service van.
9) Twist-on connector or a push-in style connector for panel and junction box splices?
The TM-RY is a twist-on, pressure-type connector: you strip, insert, and turn, and it accepts mixed conductor combinations across 18-8 AWG in one connector. A push-in style like the Ideal Industries 30-1012 INSURE connector is fixed to a single wire size, 12 AWG, with a set number of ports, so it's faster on repetitive same-gauge work but won't cover a mixed bundle. For a box with varied conductor counts and sizes, the twist-on is the one that adapts.
10) Is the NSi TM-RY a direct substitute for other pressure-type twist-on connectors I already stock?
It's the same class of device. The Wiremold W30/W30G is also a pressure-type wire connector with a steel spring, so the TM-RY sits in the same application space for copper splices in boxes and fittings. What differs is the covered wire range: the TM-RY's red/yellow combined coding spans 18-8 AWG in a single part number, so one bin replaces two color-coded bins in most installs.
11) What is the closest alternative to the NSi TERMINATOR TM-RY if I need another twist-on pressure-type wire connector?
The Wiremold W30/W30G is the nearest match in type. Both are pressure-type wire connectors with a steel spring element - the TM-RY uses a zinc-plated steel spring inside a flame retardant UL 94V-2 thermoplastic shell, and the Wiremold W30W30G is likewise described as a steel pressure-type connector in its 2000 Series. The TM-RY covers an 18-8 AWG copper wire range at 600V and 105C, so confirm the Wiremold part's range against the conductor combinations in your boxes before swapping.
12) For standardizing a facility on one wire connector, how does the NSi TM-RY compare to the other connectors available?
The TERMINATOR TM-RY is the broad-coverage choice for 600V copper branch wiring: one connector covers 18-8 AWG, it is UL Listed as a pressure-type wire connector and cULus certified, and the dual red/yellow coding means one SKU does the work of two standard connectors in most applications. By contrast the Ideal Industries 30-1012 INSURE is a 12 AWG connector, and the Burndy 9051 and 9052 IMPLO connectors and YHD aluminum line tap are tooled utility-style connectors. If the goal is a single stocked bin for junction box and panelboard splices across mixed copper sizes, the TM-RY in the 100 pack or 500 pack jar is the one to standardize on.
13) Is the shell on the TM-RY connector flame retardant?
The shell is thermoplastic with a UL 94V-2 flame retardant rating, and it provides the insulation over the spring. It's also REACH and RoHS compliant if you're specifying for a project with material restrictions.
14) Where is the NSi TERMINATOR TM-RY connector made?
Country of origin is China. Worth knowing up front if you're bidding public or institutional work with domestic sourcing requirements, since that will rule it out of those specs.
