Gardner Bender 10-004 – Frequently Asked Questions
1) What wire sizes does the yellow Gardner Bender 10-004 wire connector handle?
The 10-004 WireGard yellow twist-on connector covers #18 through #10 AWG (5 mm2) copper. Yellow is the mid-range cap in the WireGard color system, so it handles typical 14 and 12 AWG branch circuit splices as well as smaller fixture leads down to 18 AWG.
2) Can I use these twist-on connectors on aluminum wire?
No. The WireGard 10-004 is rated for copper to copper connections only. For a copper-to-aluminum splice you need a connector specifically listed for aluminum, not this one.
3) What voltage are Gardner Bender WireGard yellow connectors rated for?
600V max in building wire, and 1000V max in lighting, fixtures/luminaries and signs. That higher fixture rating is what lets electricians use the same cap inside luminaires and sign cabinets as in the branch circuit.
4) Will these wire nuts hold up in a hot fixture canopy or recessed can?
The shell is flame-retardant and resists heat distortion up to 105 degrees Celsius (221 degrees Fahrenheit), which covers the temperatures inside most fixture canopies and junction boxes. Pair that with the 1000V fixture rating and it's a common choice for luminaire wiring.
5) How does the WireGard connector keep bare wire from showing at the base?
The high-dielectric shell uses a deep skirt design that covers the conductor entry, so stripped copper isn't left exposed below the cap. Inside, a square-wire zinc-plated spring bites down and adjusts to the shape and size of the splice.
6) Do I need a tool or a torque driver to install these wire nuts?
No tool required. The 10-004 is built to reach the required torque in fewer turns by hand, and it meets or exceeds UL pull out and dielectric test requirements. Strip, align the conductors, and twist the cap on until the skirt covers the bare copper.
7) How many wire connectors come in a carton of Gardner Bender 10-004?
The 10-004 ships 100 connectors per carton. That carton measures 3.5 x 4.5 x 2.25 inches and weighs 8.15 ounces, so it drops easily into a service van bin or a stocked MRO shelf.
8) What is the manufacturer part number for the yellow WireGard twist-on connector?
Gardner Bender part number 10-004. That's the yellow #18-#10 AWG WireGard cap sold 100 to a carton, and it's the number to quote when standardizing a truck stock or a facility parts list.
