ABSTRACT:
An electrical test buzzer is adapted for insertion into an output receptacle and used to test for the presence of electricity at the output receptacle. The electrical test buzzer includes an audible alarm, a transformer, held in a housing, and a pair of contact prongs. The contact prongs are inserted into a respective output receptacle causing the buzzer to sound a high pitched alarm when electricity is present at the receptacle. When no electricity is present at the receptacle no circuit is formed and the alarm does not sound.
