NEMA Rating	IP Equivalent	NEMA Definition	IP Against Objects	IP Against Liquids
1	IP10	Enclosures constructed for indoor use; to provide a degree of protection to personnel against incidental contact with the enclosed equipment and to provide a degree of protection against falling dirt	1 = Protected against solid foreign objects of 5 cm (2 in) in diameter and greater	0 = Not protected
2	IP11	Enclosures constructed for indoor use; to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, and to provide a degree of protection against dripping and light splashing of liquids	1 = Protected against solid foreign objects of 5 cm (2 in) in diameter and greater	1 = Protected against vertically falling water drops
3	IP54	Enclosures constructed for indoor or outdoor use; to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow and windblown dust; and that will be undamaged by external formation of ice on the enclosure	5 = Protected against dust; limited to ingress (no harmful deposit)	4 = Protected against water sprayed from all directions; limited to ingress permitted
