Ideal Industries 30-073 – Frequently Asked Questions

1) Can the Ideal Wire-Nut 73B orange connector be used in a plenum or air handling space?
Yes. The Model 73B Wire-Nut is rated for air handling spaces, so it can go in plenums and above ceilings used for return air, including HVAC control and ventilation wiring. It is also UL Listed, which is what an inspector will look for on a plenum splice.
2) Is the orange 73B Wire-Nut approved for equipment grounding and bonding connections?
It is. The 73B is approved for bonding and grounding, so it can be used on equipment grounding conductors and system bonding splices rather than only ungrounded circuit conductors. Not every twist-on connector carries that approval, which is why it gets called out here.
3) Will the Ideal 73B hold fine stranded control wire, or do I need a different connector?
Fine stranded wire is one of the applications the 73B is built for, including control wiring, instrumentation and low voltage runs. The fixed square-wire spring bites into the strands instead of just compressing them, which is where round-wire springs tend to let go on fine strand.
4) Do I need a tool or a driver to install Ideal Wire-Nut 73B connectors?
No tool needed. The 73B has a positive grip shell meant for finger twisting: strip to the length NEC calls for, hold the conductors parallel, insert, and twist clockwise until tight. Then tug each conductor to confirm it is held and check that no bare copper shows below the skirt before energizing.
5) How many connectors come in a box of Ideal 73B orange wire nuts?
They ship 100 to a box. That is the contractor pack, so one box covers a full rough-in or a truck restock rather than a single device box. The part to order is Ideal 30-073.
6) What is the difference between a square-wire spring wire nut and a standard one?
The spring inside is what does the work. The 73B uses a fixed square-wire spring, whose flat edges dig into the conductors for holding power a round wire spring does not match, and it stays put instead of backing off as the splice heats and cools. That matters most on vibration-prone equipment connections and on fine stranded conductors.
