A conductor
An alternating current
An ampere
________ is a electrical safety device that is designed to prevent excessive current from passing through a circuit by blowing out or melting when a wire becomes to hot from overloading the circuit with too much current

What is the third circular electrical connection on a three-prong plug called
A circuit breaker
A grounding pin
A fuse
A ground fault interrupter
A GFI would MOST likely be required in a(n) _________
basement
office building
bathroom
bedroom
Which of the following is NOT good electrical safety advice
Read all electrical safety instructions carefully
Pull on the cord, not the plug, when disconnecting an electrical appliance
Inspect all electrical equipment regularly
Keep electrical cords off the floor and away from everyone's feet
In order to practice good electrical safety, which of the following should you ALWAYS do?
Attempt to clean around electrical outlets while equipment is plugged in.
Attempt to repair electrical appliances when they malfunction.
Twist electrical cords to protect against a short circuit.
Disconnect appliances when they are not in use.
If you receive a light shock sensation while using an electrical appliance, you should________
Unplug the appliance from the wall
Give the appliance a short break before using it again
Continue using the appliance with caution
Attempt to repair the appliance immediately
Why are ground fault interrupter (GFI) receptacles strategically placed by all sinks and in all bathrooms where you work?
GFIs are required in places where shock hazard are likely (such as near any running or sitting water).
GFIs are most useful in spas because when multiple appliances are in use, GFIs must be in place.
GFIs are most useful in spas because appliances that heat up can only operate when a GFI is in place.
GFIs are required wherever direct current is transferred to alternate current (such as in bathrooms).
If you plug a blowdryer into the outlet on the wall and it immediately starts to spark, what should you do?
you should wait for five minutes to see if the sparking stops, then continue using the blowdryer
you should unplug the blowdryer and attempt to repair it before trying to plug it in again
you should unplug the blowdryer immediately and use another dryer until that one can be repaired
you should throw the blowdryer away and immediately call the fire department
If, while using the curling iron, you accidentally drop the equipment into a sink full of water, which of the following should you do?
you should quickly unplug the curling iron from the outlet
you should quickly grab the iron out of the sink full of water
you should get everyone out of the salon and call the fire department
you should run over to the circuit breaker panel and shut down all power to the salon
