Application of a protective device that is intended to limit currents that are too small to operate fuse links, stub cables, or the fuse of a fused primary protector. [T1.318-2000]

A law of geometric optics that defines the amount of bending that takes place when a light ray strikes a refractive boundary, e.g., an air-glass interface, at a non-normal angle.
Note 1: Snell's law states that where n₁ is the index of refraction of the medium in which the incident ray travels, ₁ is the angle, with respect to the… (Read More →)
