Technician A says a short to voltage may or may not blow a fuse and may or may not affect more than one circuit. Technician B says that a short to ground (grounded) will usually cause a decrease in circuit resistance and an increase in current flow causing the fuse to blow. Which technician is correct?

A. Technician A only

B. Technician B only

C. Both A and B

D. Neither A nor B

C. Both A and B

Explanation:

Fuses are rated by the amperage they can carry before heat melts the element. The fuse is ideal for protection against short circuits. Short circuits produce enough amperage to vaporize a fuse element and break connection in one cycle of a 60-cycle system.

Specifically, the voltage rating determines the ability of the fuse to suppress the internal arcing that occurs after a fuse link melts and an arc is produced.
