b. Every 5 years
c. Every 10 years
d. Every 20 years

Answers:

1. What is the correct wattage for a light fixture?

A – The wattage should always be that which the specific light fixture requires. A higher wattage bulb may overheat, possibly causing wires or a nearby combustible material to overheat. This could lead to a fire. If you are unsure, use a bulb that is 60 watts or less. For unmarked ceiling fixtures that hold miniature bulbs, use 25 watts.

2. What objects are conductors of electricity?

D – All of the above. Electricity seeks the easiest path to the ground. It uses a conductor as a mode of transportation. Conductors include metal, wet wood, water, and a person’s body. A body is made up of 70% water. If you are standing on the ground and touch an electrical source, electricity will instantly pass through you to the ground, causing a harmful shock.

3. There are different types of extension cords for indoor and outdoor use.

A – True. Cords made for indoor use are not made to withstand the humidity, temperature and stresses of outdoor use. They are more easily damaged and can be a fire hazard. Only use extension cords outside if they are marked for outdoor use.

4. Where should you place electrical cords when plugged into an outlet?

A – Cords should be placed away from areas of high foot traffic because they can cause tripping and be damaged when stepped on. Though you want to keep electrical cords away from foot traffic, you do not want to do this by hiding them under furniture or rugs or wrapping them around a fixture. The weight of these flammable objects can crush insulation or break wire strands, creating a fire hazard. Additionally, tightly wrapped cords trap heat that would otherwise escape. This can lead to melting or weakening of the insulation. It might make sense to attach cords to a wall to avoid contact with feet or fixtures, but nails and staples can tear the insulation or cut the wires inside. The best method is to keep cords placed against a wall, away from heavy objects. Make sure they are not tightly tangled with other cords.

5. What is the best way to store your television entertainment system and its components?

B – On a shelf that does not enclose the devices. It is important that your entertainment equipment has room to breathe because blocking air flow can cause overheating. You should refer to your individual devices’ manuals for further guidance. In general, avoid enclosing equipment in cabinets unless there are proper ventilation openings. Also, never store paper around your equipment, such as manuals and guidebooks.

6. You should use water to put out an electrical fire.

B – False. Never use water to put out an electrical fire. Use a dry fire extinguisher or baking soda.

7. Which of the following is true about Ground Fault Circuit Interrupter (GFCI) outlets?

D – All of the above. A GFCI outlet monitors the current between a hot and neutral wire. If it senses an imbalance, it will break the circuit. Typically circuit breakers will do this, but they may not act fast enough. GFCIs are more sensitive and thus act quickly. These should be tested monthly by pressing the “test” button to trip the outlet and break the circuit. You can restore the circuit by pressing the “reset” button. If the test button doesn’t do anything, replace the outlet. If the outlet does pop when you press test but it still has power before pressing the reset button, it means the outlet is wired incorrectly and needs to be fixed immediately.

8. What is the best practice for light bulb use?

D – All of the above. Halogen bulbs can overheat, and thus are a fire hazard. They should be replaced with more efficient bulbs, such as compact fluorescents. When bulbs aren’t screwed in securely it can cause sparks or shorts. Lights should be turned off to avoid sparks. Also, bulbs give off heat when lights are on, so changing a bulb when the light has been on for a while can result in burns.

9. It is a good idea to periodically turn circuit breakers off and on?

A – True. Circuit breakers need to be checked to make sure they have not become stuck. This helps keep them in good working order. In addition, appliances with compressor motors can be exposed to repeat power interruptions if they aren’t shut off. Thus, flip each circuit breaker off and on three times at least once a year. Be sure to turn off the freezer, refrigerator, and air conditioner before doing this.

10. How often should the wiring in a home be inspected by a professional electrician?

C – Every 10 years. This will ensure the wiring throughout your house, particularly wires behind walls, are in good working order and comply with safety standards. If your home is more than 40 years old, an inspection is long overdue.

Additional Tips:

• Don’t ever mix electricity and water! Keep appliances and cords away from water at all times.
• Don’t use extension cords continuously. They are only temporary solutions.
• Don’t climb trees or fly kites near power lines.
• Don’t unplug a cord by pulling on the wire. Rather, pull by the base of the plug.
• Don’t force a plug into an outlet.
• Don’t stick anything in an outlet except a plug.
• Don’t overload power strips. They do not offer more power, just more access points to the limited capacity of the circuit.
• Don’t climb a utility pole or tower. Avoid power lines at all costs, even if they appear dead.
