Cord Guard For Electrical Lab Training

Cord Guard - For Electrical Lab Training Appliance provided with a supply cord, which is moved while in operation shall be constructed so that the supply cord is adequately protected against excessive flexing where it enters the appliance. Compliance is checked by flexing the whole appliance or the part of the appliance that include the inlet opening to an oscillating member so that when the supply cord is at the middle of its travel, the axis of the cord where it enters the cord guard or inlet is vertical and passes through the axis of oscillation, and is loaded by a specified force. In case of the flat cords, the major axis of the section shall be parallel to the axis of oscillation. the cord and its associated ports are turned through an angle of 90º after half the number of flexing unless a flat cord is fitted.
