1. The insulation on the power cord of a piece of class 1 equipment is faulty such that the active wire is in contact with the equipment casing. What will happen when the power cord is plugged in and the piece of equipment is turned on

A. The double insulation of the device will prevent macroshock when the outer casing is touched
B. The electrical fuse will immediately break and disconnect the device from the power supply
C. Equipotential earthing will prevent microshock
D. The Line Isolation Monitor will alarm and disconnect power to the device
E. The RCD will rapidly disconnect the device from the power supply

B - The electrical fuse will immediately break and disconnect the device from the power supply

Any conducting part of Class I equipment accessible to the user eg. metal casing, is connected to earth by earth wire. If a fault occurs which allows live supply to come into contact with an accessible part, current flows down earth wire- the new circuit has increased current which melts protective fuses and breaks the circuit- removing source of potential electrocution.

Class II- accessible conducting parts protected from live supply by double insulation

Class III- protection against electrical shock by using safety extra low voltage- not sufficient to prevent microshock therefore nto used in OT
