Cable Glands Marine Watertight
Cable Glands Marine Watertight is a group of 11 IMPA-coded items (codes 794811–794821) under Cable Accessories in the Electrical Equipment section (IMPA 79). All of them are priced per piece. The list runs through 11 metric sizes from 10 mm to 60 mm.
Buying guide
Watertight cable glands seal and grip a cable where it enters a junction box, motor terminal box, light fitting or panel. The IMPA group lists them by nominal size from 10 mm to 60 mm for electric appliances.
The electrical officer raises them for repairs to deck lighting, motors and junction boxes, where a perished or loose gland lets water into the enclosure.
How to specify it
Give the entry thread and size of the enclosure hole, the outside diameter of the cable (sheath, and armour if armoured) and the material (brass, nickel-plated brass, stainless or polyamide). IEC 62444 covers cable glands with IEC 60423 metric entry threads and is the reference standard to ask for; it excludes glands for mineral-insulated cable.[1]
State the IP rating needed. Under IEC 60529 the second numeral 5 and 6 mean protection against water jets and powerful water jets, 7 and 8 against temporary and continuous immersion; an enclosure tested only for immersion is not thereby rated for jets, so deck equipment hosed down needs a gland rated for both (dual-coded, e.g. IPX6/IPX7).[2]
Rules and certificates
IEC 62444 sets requirements and tests for the construction and performance of complete cable glands as supplied by the manufacturer, for IEC 60423 metric threads, and may guide other threads.[1]
IEC 60529 defines the IP code: the first numeral for protection against access and solid objects (6 = dust-tight), the second for water ingress (up to 8, continuous immersion, and 9 for high-pressure, high-temperature jets).[2]
In a hazardous area the gland is an Ex component of the equipment it enters: IEC 60079-0 covers the construction, testing and marking of Ex equipment and Ex components, and its 2018 edition expanded the instructions for cable gland installations.[3]
Questions buyers ask
- Is an IP68 gland better than an IP66 one on deck?
- Not necessarily. Under IEC 60529 an enclosure rated only for immersion (7 or 8) has not been shown to resist water jets (5 or 6). For deck equipment that is washed down, ask for both ratings.
- Can I use an ordinary watertight gland on Ex equipment?
- No. Glands on Ex equipment must be certified for the protection type and zone of that equipment.
