An IP code is a rating that indicates an electrical item’s ingress protection – the level of protection that the enclosure of an electrical item provides against the entry of foreign objects and moisture.
We’ve talked about this on the blog before, but all this talk of Hurricane (or Superstorm) Sandy has got us thinking about how we know whether an item is weather-resistant or not.
The IP Rating
The IP Code is known in the UK as BS EN 60529: 1992: Specification for degrees of protection provided by enclosures.
It measures two factors: the level of dust intake and water instake an enclosure allows without harming the electricals within.
In a previous post we outlined what those ratings mean:
But how do we know that an enclosure meets these requirements? There are companies that carry out rigorous tests by simulating the conditions above using specialist equipment such as nozzles of specific jets and dust chambers.
