IP55 Junction Boxes

When selecting an enclosure for your outdoor or partially covered (ie: CCTV, external lights, etc.) electrical connection, the IP55 junction box will protect your cable connection from rain, dirt, and mechanical damage. You’ll have peace of mind knowing that you are using a robust and economical method of protecting your electrical connections for your residence, commercial establishment or for your light industrial business.

What Does IP55 Actually Mean?

Ingress Protection (IP) Rating IP55 is a numbering system that provides information about how close a box is to containing the objects it was made to contain. The first digit of the IP Rating (in this case, 5) refers to the level of protection from dust and solid objects. The second digit (also 5) shows the level of protection against very low pressure water jets (such as from sprinklers, for example), and therefore complete protection against large amounts of water being forced into the enclosure.

The IP55 rating indicates that a junction box protects against most types of dust and moisture that may enter the junction box by means of environmental factors such as rain; therefore, for most practical purposes, an IP55 rated junction box is considered to provide sufficient protection of the electronic components contained within it; however, the IP55 rating does not offer complete immersion protection (i.e., underwater), nor does it protect against water jet pressures that exceed the specified level of pressure.

Key Benefits and Typical Applications

1. Water Resistant Protection

The IP55 Rated Junction Box serves to protect cable terminations and splices from moisture, rain, dust and debris when mounted outdoors. These junctions are exposed to environmental elements so they require this protection to ensure optimum performance.

2. Versatility of Installation

A variety of IP55 rated junction boxes are capable of being used in many different applications including CCTV Cabling, Outdoor Lighting, Garden Path Lighting, Alarm Systems, and External Power Outlets. They perform equally as well in garages, workshops, and other non-conventional environments.

3. Materials and Construction Durability

Most quality IP55 rated junction boxes are manufactured from durable and weather resistant plastic (such as ABS and Polypropylene) and may be further enhanced through the addition of impact-resistant materials. Each box typically features a securely fastened, screw-on lid and either pre-formed knockouts or plain sides for glands, providing flexible cable entry points and simplifying the installation process.

4. Installation and Maintenance Simplicity

The vast majority of IP55 rated junction boxes are suited to surface-mounted installations and can accommodate sealed cable entry through the use of cable glands. Proper installation will maintain the IP55 rating on dust and water ingress protection; therefore, they are suitable for both professional and DIY installations.

Important Installation Considerations

• Recommendations for maintaining the protection level of an IP55 rated Junction Box by using compatible Cable Glands (e.g. Nylon, Brass, Rubber with a step, etc.) that are rated for Outdoor use and/or for the specific type of cable being installed (e.g SWA, Flexible, Hi-Tuff, etc.)
• When drilling into the exterior of an IP55 Junction Box, it is important to drill only at the designated drill locations, as any drilling outside of these areas will penetrate the seal, thereby voiding the IP rating of the junction box.
• When drilling an IP55 Junction Box in areas with excess moisture (especially in wet conditions) using Sealing Gel and/or Internal Moisture-Proofing products can enhance the seal of the cable entry and termination.
• While an IP55 rated Junction Box will protect against Dust and Low Pressure Water Jets, an IP55 rated Junction Box will not protect the enclosure from being immersed in water or exposed to High Pressure Water Jets. Therefore, it may be advisable to use an enclosure rated at a Minimum of IP65 or IP66 for Applications requiring these levels of protection.

IP55 Junction Boxes are Ideal For –

Homeowners who want a practical and affordable method of providing weather-resistant options for garden lighting, outdoor sockets, or CCTV camera installations.

• Installers and Contractors performing installations of External Wiring in which exposure to Splashing, Rain, and Dust is of concern. They provide a level of protection from Dust and Moisture but do not require full Water Protection.
• Commercial and light-industrial applications like workshops, sheds, and loading docks, where cabling must be protected from Dust and Moisture without excessive cost related to waterproofing solutions.
• IP55 Junction Boxes are a great balance between Price, Ease of Use, and Flexibility in Wiring Schemes and provide a good alternative to basic Indoor enclosures and high-level Industrial enclosures.

Summary

With an IP55 rating, the junction box can be used to protect all of your electrical connections against damage caused by dust and/or rain or other moisture sources (providing the connections are not to be fully immersed in water). Constructed from high quality materials (such as steel), the box has been tested to withstand extreme outdoor environments. In addition to protecting against dust and moisture infiltration, the IP55 junction box provides a great deal of flexibility in terms of design as well as installation (it provides a wide variety of mounting options). In fact, the versatility of this box makes it ideal for use in many outdoor applications such as outdoor lighting, CCTV systems, and general exterior electrical installations. By using appropriate glands and sealing the entry points during installation, you will also save money by eliminating the need for more expensive alternatives when protecting your electrical networks from the elements.
