Answer / habeebm
IP (Ingress Protection) codes define how well an enclosure
protects against the external environment.
As the number gets higher, the protection gets better.
The first digit defines the protection level
against "solids", the second against "liquids". You MUST
use both digits to define an enclosure.
For the first digit:
0 = No protection
1 = Protected against objects greater than 50 mm diameter
2 = Protected against objects greater than 12 mm diameter
3 = Protected against objects greater than 2.5 mm diameter
4 = Protected against objects greater than 1.0 mm diameter
5 = Dust protected
6 = Dust tight
For the second digit:
0 = Not protected
1 = Protected against dripping water (i.e. vertical plane)
2 = Protected against dripping water up to 15 degree angle
3 = Protected against spraying water
4 = Protected against splashing water
5 = Protected against water jets
6 = Protected against heavy seas
7 = Protected against effects of immersion
8 = Protected against submersion

Answer / suresh
The name plate details of a motor which r mostly have these
type of details. Duty, Insulation Class,Temperature
class,Gas Grouping,Protection Types.etc...
But most of the motors have E.// 2G EX-d, //I,T4, IP55. if
u want to know all these details u can refer the site
Hazardus area equipment.

what is transformer tap change HT side and LT side
Define Electrical Insulation and examples of Solid,Liquid and Gaseous insulating materials?
I do wonder why current is present in neutral wire?i check single phase lead current feeding air conditioner...on its phase its current was 10A while same was 10A in neutral...as we know in neutral voltage is zero so if voltage is zero then how current appears on amp meter? my second observation is (just imagination)when I touch phase wire it give me shock but when i touch neutral nothing happens although as above its carrying current(amps) third but with same logic...as in simple Alternate current sine curve there is + and there is negative peak.means every time phase changing so how come every time same phase and same neutral stand (pardon for english mistakes)
