I do not see anything in that section about open noodles.
Looks like it is more that you just have to use listed etc GFCI cord sets.
No homemade or el cheap knock offs.
It appears that the only GFCI open neutral product available is a cord set device. I was hoping to find a GFCI open neutral receptacle to replace the existing GFCI receptacles and not have the added cost of purchasing 100 plus GFCI open neutral cord sets to meet the new 2017 NEC 525.23(D) requirements.
Enclosed is some information from the NFPA website - NEC Report on Proposals (ROP) and Public input (PI) concerning the new 2017 NEC sub-section 525.23(D).
Public Input No. 2558-NFPA 70-2014 [Section No. 525.23]
Statement of Problem and Substantiation for Public Input
This is admittedly enforceable through 110.3(B) because of the guide card restrictions on the product (category KCXS) in that they are “flush receptacles and are intended to be installed in an outlet box for fixed installation on a branch circuit similar to a conventional receptacle.” Therefore it is at least implied that these devices are prohibited to be installed at the end of a flexible cord. Nevertheless, the lack of black-letter Code rule on this topic in conjunction with the somewhat vague guide card restriction has routinely resulted in extensive application of these temporary GFCI set-ups at fairs and carnivals. This submitter was recently overruled when he objected to approximately 40 of these at an actual event. Note that the rule in 590.6 is limited to construction sites and similar venues, and cannot be applied to carnivals and fairs. These devices are a recognized hazard when connected to temporary wiring because the neutral continuity can and has opened in the field. If this happens, the device loses its brains because it no longer sees 120 volts, and it fails closed. This has resulted in a number of documented fatalities on construction sites, which is why there is a comparable restriction [590.6(A)(2)] to that proposed here. The overwhelming majority of temporary wiring for fairs and
carnivals uses flexible cord, and the listing restriction is widely overlooked. This proposal will provide the necessary awareness.
This concept was accepted by CMP 15 during the proposal stage for the 2014 NEC, but rejected during the comment stage over the vehement objections of both NEMA and UL. The UL objection is particularly on point: “Open neutral protection is an important GFCI feature, especially in applications dealing with abuse and wear. Sam Sampson, in his IAEI Article entitled ‘Electrical Inspections for Carnivals, Fairs and Traveling Shows’, points out that plug and socket connections in those venues are subject to damage and wear. Quoting from this article, ‘Cords are often damaged by exposure to oils, gasoline, direct sunlight, foot and vehicular traffic, arriving on site worse for the wear. Distribution boxes and cords are unloaded at each stop in various stages of disrepair.’ The article goes on to state, ‘With the safety of the carnival workers and the public at stake, it is important to check the entire distribution system for properly sized over-current devices, grounding and bonding continuity and GFCI functionality.’ Portable GFCIs with open neutral protection provide the protection needed to deal with worn cord and plug connections. ”
The gravamen of the panel rejection centered on the impracticality of providing portable GFCI protection for what could be all receptacle outlets at a carnival, because all wiring at some point runs in flexible cord. This public input has been modified from that submitted in the 2014 cycle to clarify that it only applies to the actual branch circuit supplying one or more receptacles; if a feeder runs in flexible cord to some sort of distribution point, it would be permitted to install conventional GFCI receptacles at that point. The panel made a comparable change during the proposal stage, but the adverse public comments erroneously stated that all receptacles would be covered by this requirement anyway. The arrangement permitted by this wording is frequently done using so-called spider boxes and can be done safely. However, placing a conventional GFCI on the end of a flexible cord violates 110.3(B) and should not continue to the extent it is now practiced.
The objections to the concept presented here, as expressed in commentary on the ballots for the 2014 cycle, do not appear to be consistent with safe wiring practices. In effect, they support the use of GFCI receptacles intended for use in permanently wired outlets and installed atthe end of temporary wiring, in complete violation of their listing. The only possible way to remove this direct conflict with the established listing limitations would be to insert a Chapter Five exception in this section to the provisions of 110.3(B), an action that would be unprecedented in the history of the NEC.

Committee Statement
Committee Statement: This First Revision incorporates a requirement for identified portable GFCI receptacles, but only on branch circuits fed by flexible cord. GFCI’s installed in portable structures or rides are not required to utilize identified portable GFCI’s, even though such structures and rides may be fed by flexible cord
feeders. This introduces the desirable additional safety afforded by open-neutral sensing in identified portable GFCI’s in specific applications, without extending that requirement to receptacles permanently installed in structures or rides, which would be impractical.

525.23 Ground-Fault Circuit-Interrupter (GFCI) Protection.
Where GFCI protection is provided through the use of GFCI receptacles, and the branch circuits supplying receptacles utilize flexible cord, the receptacles shall be identified for portable use.
(A) Where GFCI Protection Is Required. GFCI protection for personnel shall be provided for the following:
(1) All 125-volt, single-phase, 15- and 20-ampere non-locking-type receptacles used for disassembly and reassembly or readily accessible to the general public
(2) Equipment that is readily accessible to the general public and supplied from a 125-volt, single-phase,15- or 20-ampere branch circuit . The ground-fault circuit-interrupter GFCI shall be permitted to be an integral part of the attachment plug or
located in the power-supply cord within 300 mm (12 in.) of the attachment plug. Listed cord sets incorporating ground-fault circuit-interrupter GFCI for personnel shall be permitted.
(B) Where GFCI Protection Is Not Required. Receptacles that are not accessible from grade level and that only facilitate quick disconnecting and reconnecting of electrical equipment shall not be required to be provided with
GFCI protection. These receptacles shall be of the locking type.
(C) Where GFCI Protection Is Not Permitted. Egress lighting shall not be protected by a GFCI.
(D) Receptacles Supplied by Portable Cords. Where GFCI protection is provided through the use of GFCI receptacles, and the branch circuits supplying receptacles utilize flexible cord, the GFCI protection shall be listed, labeled, and identified for
portable use.

Statement:
Per the Correlating Committee comment, this Second Revision alters the section numbering in order to comply with the NEC Style Manual. CMP-15 adds a first level title. The term “receptacles” is changed to “GFCI protection...listed, labeled and” for clarity.
