bronafon relax breath out the mian ip codes you have to remember are IP2X and IP4X

The first cope IP2x meand the whole is no larger then 12mm and no live parts are accessable using a BS test figer which is hinged in 2 places.

Ip4x is no access using a 1mm probe.
The X means it not rellevent

Wotsit is quite right in his reply and has given a good link showing the different codes.

Basically IP stands for International Protection (Often known as Ingress Protection or Index of Protection) and they state different requirements for enclosures from ingress by solid objects and liquids.

The first number is for solid objects from a small sphere down to a grain of dust.

The second number is for liquids from a shower of rain through to totally submersible (to a depth).

There is often a additional letter which has a set meaning.

If you are revising for the 2391 written exam the 2 most popular ones are IP 2X and IP 4X.(Note that X means ignore this number in the code - all liquid codes are ignored).

IP 2X or IP XXB is known as a standard test finger and is used to identify holoes in an enclosure such as those left by removal of a conduit or armoured gland.


IP 4X or IP XXD is a standard test wire and is used to check ingress of a wire into a readily accessible, top horizontal surface of an enclosure (such as a wire falling into a fuseboard through knockouts left in the top.

Does this help?

IP - Ingress Protection

I generally think along the lines of the first digit being protection against physical contact (eg vandalism, objects...) and the second digit being protection against liquids (eg rain, splashes...).

The higher the number (digit) the greater the level of protection.
