An IP rating is the start of a weatherproofing specification, not the whole of it. The rating in a model’s file — IP54, IP65 or IP66 across the EVDANCE range — speaks to dust and water reaching the enclosure. Salt air, wind-blown sand, heat and ultraviolet light attack different things: fasteners, connector contacts, cable jackets, finishes and labels. A coastal or desert project therefore writes each exposure as a question, and files the supplier’s written answer against the exact model before the specification is issued.
Key Takeaways
- Weatherproofing starts at the stated IP rating and continues exposure by exposure: salt, sand, heat, UV, driving rain.
- Each exposure becomes a written question; the answer filed is the listing’s statement or a supplier confirmation.
- No model is “coastal rated”, “marine grade” or desert rated — those words never enter the specification.
- Siting and maintenance carry the other half: shade, orientation, drainage and scheduled inspection.
The Exposure Table
| Exposure | What it attacks | The spec question | The stated evidence to file |
|---|---|---|---|
| Salt-laden air | Fasteners, seams and the connector’s exposed contacts — corrosion on metal the enclosure rating does not cover | What enclosure, finish and fastener materials does the listing state for this model? | The materials as listed, or a written confirmation. No “coastal rating” exists to quote |
| Wind-blown sand and dust | Seals, connector faces and latches that grit works into | What dust protection does the model’s stated IP rating represent, and how does the connector park between sessions? | The stated rating, plus the parking arrangement the specification itself sets |
| Heat and direct sun | Enclosure temperature, cable jackets and the unit’s session behaviour | What operating temperature range does the file state for this exact model? | A written figure — the EVDANCE listings state none, so this is a confirmation, and shade becomes a siting decision |
| Ultraviolet exposure | Cable jackets, plastics and printed labels | Is UV resistance stated for the jacket and the housing? | The listing’s statement, or a written confirmation where the listing is silent |
| Driving rain and wash-down | Enclosure seams and cable entries | What water protection does the stated IP rating represent at this position? | The rating as listed for the exact model — the table below |
The Ratings the Listings Actually State
These are the ingress ratings as listed. What the digits mean, test by test, is covered in our guide to IP ratings for EV chargers; the discipline here is simpler — a specification may only use the rating the file states.
- The EV-AC03201T dual-connector AC station states IP54. The EV-RHDC30K-L compact DC charger states IP54.
- The EV-ACT3204PE 22 kW wallbox states IP66, as listed. The EV-ACT5006T 48A wall charger states IP66.
- The EV-ACS4005T, EV-AC04001U, EV-ACS3210T, EV-ACS3210E and EV-ACS3205PE portables state IP66 each; the ACS1605PE states IP66.
- The JT02 AC adapter states IP65. The JT08 and JT09 DC adapters state IP66 — for use only where the vehicle maker approves a third-party DC adapter for the exact car and the station is open to that car.
Two warnings belong in every weatherproofing specification. An IP rating is not an impact rating and not a corrosion rating; it answers the ingress question only. And a rating is a property of the model tested — it does not transfer to a sibling model, a different configuration or a private-label variant without a file of its own.
Siting Is the Other Half of the Spec
Hardware evidence is half the answer; the site does the rest. Shade, orientation away from the prevailing spray or wind-blown sand, drainage at the unit’s base and covered parking are project decisions, and our hot-climate charging guide works through the desert siting side in detail. Maintenance closes the loop: exposed contacts and finishes are inspection items in the site’s schedule, because a specification can only file the evidence — the site has to keep it true. For a coastal or desert model shortlist, send the exposure list with your enquiry via contact us or start from the commercial EV charging page.
Frequently Asked Questions
Is IP66 enough for a beachfront car park?
It answers the dust and water question. The salt question — corrosion of fasteners, seams and contacts — needs materials evidence in writing for the exact model. No EVDANCE model is specified as “coastal rated” or “marine grade”, and the specification should not use those words.
Which EVDANCE charger is rated for desert heat?
None is sold with a desert rating, and the listings state no operating temperature range. Confirm the range for the exact model in writing, then handle shade and siting in the project design.
Does a higher IP number mean better corrosion protection?
No. The code rates ingress — dust and water. Corrosion and impact are separate properties, each with its own evidence line in the model’s file.
