Thomas & Betts 10RC-10X – Frequently Asked Questions
1) Will a 12-10 AWG ring terminal fit over heavy wall THHN insulation?
Yes, that is the point of the X suffix on the 10RC-10X. The expanded insulation grip gives a wider wire entry and accepts insulation up to 0.25 inch outside diameter, so heavy wall THHN and machine tool wire slide in without having to strip back extra jacket or trim the insulation.
2) Is this ring terminal rated for 600V control wiring?
Yes. The 10RC-10X carries a 600V rating with a 105 degrees C temperature rating, which covers typical control panel, motor connection and fixture whip work. It is UL and CSA recognized and the vinyl insulation is UL 94 V-0 flammability rated.
3) I need a ring terminal for 6 AWG on a #10 stud, not 12-10. What should I use?
The 10RC-10X tops out at 12-10 AWG, so it will not accept 6 AWG. For that conductor on the same stud, the Burndy YAV6CL1BOX Hylug is a 6 AWG one-hole ring terminal sized for a #8-10 stud. That is a heavier uninsulated-style lug, so plan on a compression tool suited to Hylug dies rather than a vinyl terminal crimper.
4) What ring terminal should I use for 6 AWG wire on a #10 stud instead of the Thomas & Betts 10RC-10X?
The Thomas & Betts 10RC-10X is built for 12-10 AWG wire on a #10 stud, so it will not accept a 6 AWG conductor. For 6 AWG on the same stud, the Burndy YAV6CL1BOX Hylug ring terminal is a one-hole lug sized for 6 AWG with a #8-10 stud hole, which covers the #10 stud while taking the heavier conductor.
5) Is the Burndy YAV6CL1BOX a direct replacement for the Thomas & Betts 10RC-10X?
No. They share a stud range overlap at #10, but they are sized for different conductors and built differently. The 10RC-10X is an insulated copper terminal with an expanded vinyl insulation grip rated 600V at 105 degrees C for 12-10 AWG. The Burndy YAV6CL1BOX is a Hylug one-hole lug for 6 AWG with a #8-10 stud hole. Match the terminal to the conductor you are landing rather than to the stud alone.
6) What crimp tool do I need for the 10RC-10X ring terminal?
ERG4001 is the recommended tool. WT145C, WT2000, WT112M and ERG4003 are also listed as application tools for it. Because the barrel is an expanded insulation grip, use a tool with the correct nest for insulated vinyl terminals rather than a bare-lug die.
7) How do I identify the right size insulated ring terminal by color?
On the Thomas & Betts RC series, the 12-10 AWG terminals are yellow, so the 10RC-10X has yellow vinyl insulation. If the wire on your panel is color-coded blue (16-14) or red (22-16) at the terminal, you are looking at a smaller barrel and the 10RC-10X will not grip it properly.
8) How many ring terminals come in a pack, and is there a minimum order?
The 10RC-10X is sold by the each, but it moves in multiples of 50. Inner package is 50 pieces and the full outer carton is 2,500. Weight runs about 5 lbs per 1,000 pieces, useful if you are shipping a large MRO restock.
9) My 12-10 AWG wire has thick-wall insulation and the standard terminal barrel will not slide over it. What should I order?
Order the Thomas & Betts 10RC-10X. The X suffix in the catalog number means an expanded insulation grip, a wider wire entry made to accept heavy wall insulation, and it takes insulation up to 0.25 inch outside diameter. The Burndy YAV6CL1BOX is a 6 AWG lug and is not an option for a 12-10 AWG conductor.
10) Is the 10RC-10X terminal copper, and is it RoHS compliant?
The barrel and ring are copper with an electro tin-plated finish, and the part is RoHS compliant. Stock thickness is 0.040 inch. Tin plating over copper is what you want against aluminum-free copper conductors and plated steel studs in damp or indoor commercial panels.
11) If I am standardizing on one crimp tool, how do the 10RC-10X and the Burndy Hylug differ?
The Thomas & Betts 10RC-10X is an insulated RC series terminal crimped with hand tools such as the ERG4001, which is the recommended tool, with WT145C, WT2000, WT112M and ERG4003 also listed. The Burndy YAV6CL1BOX belongs to the Hylug family of one-hole lugs for 6 AWG, a heavier conductor class that is a separate die set. Running both means tooling for two distinct terminal families.
