What is an IP rating and what the hell do they mean?

IP Ratings…So what the hell are they?
 IP (or “Ingress Protection“) ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.
And what the hell do they mean? 
Quick IP rating hacks for Exterior Range/Suitability of installation for different IP rated products:
  • IP20 – Non-protected from solid particles and water – fitting can only be installed indoors
  • IP44 – Protection from solid particles of Φ1mm in size and splashes of water from all sides – fitting can be installed outdoors but has to be under cover
  • IP54 – Limited protection from ingress of dust and splashes of water from all sides – fitting can be installed outdoors but has to be under cover
  • IP65 – Total protection from ingress of dust and hosing jets of water from all sides – fitting can be installed outdoors in open without any covers
  • IP66 – Total protection from ingress of dust and strong hosing jets of water from all sides – fitting can be installed outdoors in open without any covers

There you go, easy peasy!
