IP and IK ratings describe different tests; enclosure selection also needs attention to connectors, site exposure and maintenance access.
Check the stated IP and IK ratings for the complete installed equipment, including connectors and cabinets. The enclosure needs to suit the site's rain, dust and impact exposure, with manufacturer documentation supporting the proposed arrangement.
Those ratings answer specific test questions. Corrosion, direct sun and safe maintenance access still need attention, even when an enclosure carries a familiar protection code.
Outdoor equipment protection developed separate classifications for ingress and mechanical impact. IP and IK provide a shared test vocabulary in place of broad descriptions such as weatherproof or vandal-resistant.
A component classification is only part of the installation picture. Cable openings, connector seals, the lens window and any field modifications affect how the equipment is assembled and maintained.
The highest available rating is not automatically necessary. A sheltered position and an exposed roadside mount present different conditions. The specification should follow the actual exposure and impact risk rather than using a single rating for every part of the lane.
Location and maintenance arrangements remain practical choices alongside the housing. A well-rated enclosure can still have an incorrectly sealed opening or be placed where servicing is difficult.
In IP66, the first 6 means dust-tight protection and the second means protection against powerful water jets under the specified test. Neither digit states a temperature limit, and IP66 alone does not establish suitability for immersion. The installation evidence should also identify the manufacturer's sealing requirements for the supplied connectors and cable entries.
IK10 is a 20-joule impact classification. A 5 kg mass falling about 0.4 m has roughly that potential energy, but this illustration does not reproduce the prescribed test. The classification does not cover every tool, repeated attack or vehicle collision. Inspection after servicing and impacts remains relevant.
SolarLink describes a managed fixed-site system. Its public description does not establish IP66 or IK10 for every component supplied as part of an installation.
An equipment schedule should identify the exact ratings and installation conditions. That connects the protection evidence to the supplied assembly rather than the product family name.
