Ideal Industries 30-071 – Frequently Asked Questions

1) Can the Ideal 71B Wire-Nut be used for grounding and bonding splices?
Yes. The 71B gray Wire-Nut is UL Listed and approved for bonding and grounding, so it can be used on equipment grounding conductor splices as well as ordinary hot and neutral connections.
2) Is the gray 71B connector allowed in a plenum or air handling space?
It is. The 71B is rated for air handling spaces, which covers plenum wiring, HVAC control and ventilation connections made above ceilings per NEC requirements for those spaces.
3) Will the 71B Wire-Nut hold fine stranded control wire, or do I need a different connector?
Fine stranded conductors are covered. The 71B uses a fixed square-wire spring that grips stranded conductors, and it is called out for control wiring, instrumentation and low-voltage splices as well as solid building wire.
4) What is the difference between a square-wire spring Wire-Nut and a round-wire twist-on connector?
The spring inside is what does the work. Ideal's Wire-Nut connectors, including the 71B, use a precision square-wire spring that bites into the conductors for gripping force and electrical contact, rather than the round-wire spring used in some other twist-on connectors. The shell is thermoplastic with a positive grip profile so it can be run down by hand without a driver.
5) Do I need to pre-twist the conductors before installing a Wire-Nut 71B?
No pre-twisting is required. Strip the conductors clean, hold them parallel and push them fully into the connector, then twist the 71B clockwise with firm pressure until the wires are gripped. Tug each conductor to confirm, and check that no bare copper shows below the shell skirt.
6) How many Ideal 71B connectors come in a box?
The 71B gray connector, Ideal part number 30-071, is packed 100 pieces to a contractor box.
7) Is the gray 71B the right Wire-Nut for commercial and industrial panel work, or is it a residential-only connector?
It is used in both. The 71B is listed for branch circuit, switch, receptacle and fixture splices in housing, and equally for office, retail and institutional wiring, control panel connections, motor leads and equipment grounding in industrial work.
