Ideal Industries 30-310 – Frequently Asked Questions

1) What wire sizes does the IDEAL 30-310 Model 10 set-screw connector take?
The IDEAL 30-310 Model 10 set-screw wire connector covers 22 through 10 AWG conductors, so it handles everything from low-voltage control and thermostat wire up through 10 AWG branch circuit conductors. That range is why it is a common single-part stock item on a service truck instead of carrying three twist-on sizes.
2) Is the IDEAL 30-310 wire connector UL listed for use in a junction box?
Yes. The 30-310 is UL listed to 486C and CSA Certified to C22.2 #188, and it complies with Federal Specification W-S-610E. Those are the connector listings an inspector looks for on a splice, and the W-S-610E reference is what lets it be used on federal and institutional work with that spec on the drawing.
3) Will a set-screw connector like the IDEAL 30-310 hold up in a high-temperature fixture or ballast compartment?
The shell on the 30-310 is flame-retardant and rated at 150 C (302 F), which covers luminaire and ballast compartment splices where ordinary low-temp connectors are not appropriate. Confirm the fixture's own marked splice temperature before you rely on it.
4) Should I use a set-screw connector or a twist-on wire nut for a motor or equipment splice that vibrates?
Use the set-screw type. On the IDEAL 30-310, the screw applies direct mechanical compression to the conductors, which gives a vibration-resistant splice; a twist-on relies on the spring insert and can loosen under sustained vibration. Set-screw is the usual choice around motors, HVAC equipment, and machinery.
5) Can you reopen an IDEAL 30-310 connector and reuse the same wire ends?
Yes, that is a big part of why service electricians keep them. Backing off the set screw releases the conductors without deforming them, so you do not have to re-strip the wire every time the connection is disturbed. Handy on troubleshooting calls where a splice gets opened repeatedly.
6) Can you tell if the splice is made correctly without taking the connector apart?
The 30-310 shell permits fast visual inspection of the splice, so you can confirm the conductors are fully seated under the screw without disassembly. That matters on inspected work and on large installs where a foreman is spot-checking splices.
7) How many connectors come in an IDEAL 30-310 box?
The 30-310 ships as a box of 1,000 Model 10 connectors. That is a bulk contractor pack rather than a jar or a counter card, so it suits a full rough-in, a panel change-out program, or MRO stock for a facility that standardizes on one connector.
