Ideal Industries 30-311 – Frequently Asked Questions

1) What wire sizes do IDEAL 30-311 set screw wire connectors handle?
The 30-311 set screw connectors are rated 600V and cover 22 through 10 AWG. The published combination range runs from a minimum of one #14 with one #20 up to a maximum of three #14 with two #18, so they cover both light control-wire splices and standard branch-circuit conductors. Brass sleeve inserts come in three sizes to span that range.
2) Why use a set screw wire connector instead of a twist-on wire nut?
Vibration is the deciding factor. A set screw connector clamps the conductors under screw compression, which holds a splice near motors, compressors, and other vibrating equipment where a twist-on can loosen. It also lets you break and remake the connection without re-stripping the wire each time, and the splice stays visible for inspection before the cap goes on. For a static junction box splice, a twist-on is quicker; for motor leads and equipment connections, this is the type to use.
3) Are IDEAL 30-311 set screw connectors UL listed and CSA certified?
Yes. The 30-311 connectors are UL listed to 486C, CSA Certified to C22.2 #188, and comply with Federal Specification W-S-610E, which is what a government or institutional spec typically calls for on a splice connector.
4) Do IDEAL 30-311 connectors come with the insulating caps and the set screw holder, or do I order those separately?
Both are in the package. Each package of the 30-311 set screw connectors includes plastic caps to insulate the splice after installation, plus a set screw holder to make driving the screw easier. Nothing extra to order to complete the splice.
5) How hot can IDEAL set screw wire connectors get before the shell fails?
The shell on the 30-311 is a flame-retardant material rated at 150 C (302 F). That covers high-ambient work like motor terminal boxes, luminaire compartments, and mechanical rooms where a lower-rated insulator would be marginal.
6) How many connectors are in an IDEAL 30-311 carton?
The 30-311 ships as a carton of 1,000. That is a stocking quantity for a contractor or MRO crib standardizing on set screw splices, not a small counter pack.
7) Can I reopen an IDEAL 30-311 splice for troubleshooting and put it back together?
That is the point of the set screw design. Back the screw off, pull the conductors, and remake the connection without cutting back and re-stripping the wire. The cap slips off for inspection and the splice can be checked visually before you close it back up, which matters on equipment that gets serviced repeatedly.
8) What is the manufacturer part number for the IDEAL set screw wire connector?
IDEAL Industries 30-311. That is the number to quote for the set screw wire connector supplied in the 1,000-piece carton.
