Wiring duct for panels and enclosures · Slot style and size, PVC versus halogen-free material, continuous-use temperature, UL 94 flammability, mounting and covers
A cable management duct (wiring duct) is a rigid plastic channel with slotted or solid side walls and a snap-on cover, fixed inside control panels, racks and battery enclosures, that routes, separates and protects wires between components while letting them leave the duct at any slot. Ask three things first: the width, height and slot style needed for your wire bundles, the material and its continuous-use temperature in the enclosure, and the flammability rating and mounting method required.
Slotted and solid-wall plastic wiring duct with covers for control panels, telecom racks and battery enclosures. Building cable trays and ladders, conduits, surface raceway for walls and cable tray roll-forming machines are outside this page.

Panduit's Panduct catalogue page lists wiring duct styles including wide-finger flush (Type G), narrow-finger flush (F), solid-wall flush (FS), wide-finger hinged (H), round-hole flush (D), halogen-free, NORYL wide-finger (NE) and low-smoke metric designs, with base and cover sold separately in 6 ft lengths. Type G black duct runs from 23.6 × 51.6 mm (0.93 × 2.03 in) to 108.0 × 129.5 mm (4.25 × 5.10 in) overall. [1]
The G2X2WH6-A data sheet describes a nominal 2.0 × 2.0 in (50.8 × 50.8 mm) wide-slot duct, 57.2 mm wide and 53.8 mm high overall, 1.8 m long, with 7.9 mm slots; its wide finger and slot design gives greater sidewall rigidity, and score lines allow fingers and sidewall sections to be removed. [2]
Editorial calculation: a 10 m duct run in 1.8 m (6 ft) lengths needs 10 ÷ 1.83 ≈ 5.5, so six base lengths and six covers, before allowing for offcuts at corners and tees. [2]
A second maker's table adds wall thickness, slot geometry and wire capacity. Changhong Plastics (CHS) lists its grey PVC slotted duct (PXC series) from 20 × 15 mm to 130 × 100 mm (height × width), with 1.5 mm wall thickness on the smaller sizes, 1.8 mm on sizes such as 50 × 55, 50 × 60, 60 × 60 and 65 × 65 mm, and 2.1 mm on 50 × 100, 60 × 100 and the 100 mm and 130 mm heights. Slot width (A) runs 4, 6, 8 or 10 mm with slot pitch (B) of 6, 8, 9, 10 or 12 mm, and the table states a contained-wire capacity in 1.5 mm² wires: 5–10 for 20 × 15 mm, 45–55 for 40 × 40 mm, 90–100 for 50 × 50 mm and 220–250 for 50 × 100 mm and 350–500 for 130 × 100 mm. [3]
Editorial calculation: doubling the CHS duct from 50 × 50 mm to 50 × 100 mm raises the stated 1.5 mm² wire capacity from 90–100 to 220–250, about 2.4 to 2.5 times; ask each supplier for its own fill table at the wire size you use rather than scaling by area. [3]
Give the supplier the duct width and height, slot style (wide or narrow finger, solid wall, round hole), length, colour, material (PVC, halogen-free, low-smoke), required continuous-use temperature, flammability rating, mounting (holes, adhesive, DIN rail), cover type, certifications and quantities.
02
Panduit's Type G duct is made of rigid PVC (lead-free in the G2X2WH6-A), rated UL 94 V-0, with a UL-recognised continuous-use temperature of 50 °C (122 °F); Panduit states it conforms with NFPA 79-2002 section 14.3.1 for flame-retardant material. The same catalogue offers halogen-free and NORYL duct styles as separate types. [1] [2]
The data sheet notes that adhesive tape is not meant for permanent mounting of wiring duct; a mounting hole at each end is exposed for permanent fixing with fasteners, and surfaces should be clean, dry and grease-free. The duct is listed as RoHS compliant, UL recognised and CE compliant. [2]
Editorial note: battery enclosures and panels with heat-producing devices can exceed 50 °C locally; ask the supplier for the continuous-use temperature of the specific material and for any halogen-free or low-smoke requirement your project specifies.
Ratings differ by maker and test basis: CHS describes its grey PVC duct as heat-resisting up to 85 °C, while Panduit's Type G PVC carries a UL-recognised continuous-use temperature of 50 °C. Ask which test or listing a quoted temperature comes from before comparing them. [3] [1]
03
IEC 61084-1:2017 "specifies requirements and tests for cable trunking systems (CTS) and cable ducting systems (CDS)" that hold, and where necessary give electrically protective separation for, insulated conductors, cables and other equipment in electrical or communication installations with a maximum voltage of 1 000 V AC and 1 500 V DC. It excludes conduit, cable tray, cable ladder and power track systems. The second edition, published on 22 March 2017, replaced the 1991 first edition and its 1993 amendment, with changes to classification, construction, and mechanical and electrical properties; a European adoption is listed as FprEN IEC 61084-1:2024. [4]
The ratings this page already lists are North American: Panduit's Type G duct is rigid PVC rated UL 94 V-0 with a UL continuous-use temperature of 50 °C, and Panduit cites NFPA 79 for flame-retardant material [1] [2]. For panels built to IEC rules, ask whether the duct and cover are tested as a system to IEC 61084-1 with its relevant Part 2, which classification applies, and whether it is used for the protective separation of circuits, which the standard addresses.
Changhong (CHS) lists wall thicknesses of 1.5, 1.8 and 2.1 mm by size and a heat-resisting grade "up to 85 °C" [3]. Ask each supplier for the test standard behind any temperature and flammability claim, since a UL file and an IEC 61084 classification are separate assessments.
Editorial calculation: the 2017 edition replaced one published 26 years earlier (1991); the 1 000 V AC limit is four times a 250 V control circuit. [4]
