Q: Which is cheaper to run: LED or fluorescent?

• <div><p>Just as fluorescent lights are more efficient than incandescent lights, LED lights are more efficient to run than fluorescent lights. The specifics will vary from product to product, but LED lights are typically twice as efficient as equivalent fluorescent lights. A 13-watt CFL bulb can replace a 60-watt incandescent bulb, but a 6- to 8-watt LED bulb can offer the same amount of brightness. Fluorescent lights offer about 50 lumens per watt, while LEDs offer about 100 lumens per watt. LED light bulbs typically last two to three times as long as CFL bulbs, too. </p></div>

Q: Do both switches need to be on for a 3-way switch?

• <div><p>No, both switches do not need to be on for a 3-way switch to work. When the two switches are in opposite positions, the circuit is open and the light is off. Flipping either switch closes the circuit and turns the light on. So, either switch can turn the light off independently, and both switches do not need to be in the same position for the switch to function.</p></div>

Q: What is the standard electrical outlet?

• <div><p>A 3-prong, 15-amp, 120-volt outlet is standard in the U.S. These have two vertical slots and a U-shaped grounding hole, which suits most home electronics, from televisions to microwaves. Three-pronged outlets are safer than 2-pronged ones, as the third wire, known as the grounding wire, helps prevent shocks and electrical fires.</p></div>

Q: How do you upgrade the electrical system in older homes?

• <div><p>To upgrade electrical systems in older homes, you might need to reroute new wires with lath and plaster walls. That&rsquo;s because it&rsquo;s more challenging to get inside the walls of an older home compared to a modern home, which usually uses drywall. But there are easier ways to level up your electrical game in an older home. For instance, you can swap out an old furnace for a new electric heat pump, or you could use a heat pump for water heating. </p></div>

Q: Where do I need GFCI outlets?

• <div><p>According to the National Electrical Code (NEC), GFCI outlets should be installed in wet or damp locations where they might be splashed with water or other liquids. This is to protect against ground faults, which are more common around water. Specific areas that require GFCI outlets include kitchens (especially near counters), bathrooms, laundry rooms, basements, garages, and all outdoor receptacles. Depending on local electrical codes, you may need at least one GFCI outlet in these rooms, or every outlet in the area may need to be GFCI protected.</p></div>
