Metallics MQDC2218F – Frequently Asked Questions
1) What wire size does the Metallics MQDC2218F quick disconnect terminal accept?
The MQDC2218F is sized for #22 through #18 wire, so it covers the small-gauge end of control, signal, and low-voltage runs. If your conductor is #16 or larger, this barrel won't crimp down on it properly and you need a terminal rated for the heavier gauge.
2) Is the MQDC2218F a male or female quick disconnect, and what tab size does it fit?
It's the female (receptacle) half of a 250 series quick disconnect, meaning it slides onto a 1/4 inch wide male tab or the mating male QDC. Order the male counterpart or confirm the device terminal is a 250 tab before crimping these on.
3) Can I use the MQDC2218F for appliance and HVAC control wiring connections?
That's the usual application. A 250 series female quick disconnect on #22 to #18 wire is what you land on blower motors, limit switches, relays, thermostats, and similar line-voltage and control terminals that come with a 1/4 inch spade tab. It gives you a pull-apart connection for service instead of a soldered or screwed joint.
4) Do I need a special tool to install the Metallics MQDC2218F terminal?
Yes, it's a crimp terminal, not a screw or push-in connector. Use an insulated-terminal crimper matched to the #22 to #18 range; pliers will deform the barrel and leave a joint that pulls off under vibration. Strip the conductor, seat it fully in the barrel, and crimp once.
5) How do I order the right Metallics quick disconnect for a larger wire gauge?
The MQDC2218F covers only #22 to #18. For heavier conductors you need a different gauge band in the same 250 QDC family, matched to the wire you're landing, and you still have to pick female or male to suit the device tab. Match the gauge first, then the gender.
