Shock Cord

Why is not common to leak on a area of concern related products vs. fixed cord cabling products?

Why is it that in assessments of product safety leakage current test is performed on the cord connected product, why not fixed / Facilities permanently connected. The ground is still most often linked to the compound and a potential electric shock to the user.

Cord connected products are likely to be suspect at a higher rate of failure of system grounding, or neutralization of the head grounded. This can be in normal use the camera is moved, the cord is bent, and the plug is repeatedly inserted and removed from the taking of his life. Second, cord products, powered hand tools in particular are more often in contact with the operator, so they have a higher risk of electric shock, in this regard. Third, wireline products tend to see more abuse (fall, etc.) than something that is permanently placed. Fourth, a fixed generally more than one path to ground available. If a single ground wire is essential, conduct also provides a dirt road. This makes controlling the connection to the earth a little more complex than it might be the realization of a land through several channels or more, one of which must be grounded.
