Q: Is pigtail wiring safe?

• <div><p>A pigtail is the only safe way to connect an electrical device to more than one circuit wire. Connecting multiple wires to a single screw terminal is extremely dangerous and must never be done. Many electricians will opt for pigtails even when there are multiple screw terminals available so that the device in question won&rsquo;t halt the flow of downstream current when a problem arises. </p></div>

Q: Can you replace a circuit breaker without turning off the main breaker?

• <div><p>Homeowners should avoid replacing a circuit breaker without turning it off. While you technically can replace a circuit breaker without turning off the main breaker&mdash;and professionals can and do&mdash;it&rsquo;s only safe for electricians to use this process. Working with a live panel is extremely dangerous if you don&rsquo;t have experience working with electricity. Always follow safety measures to avoid electrical shock.</p></div>

Q: Where does a C-wire connect on a furnace or HVAC system?

• <div><p>A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled &quot;C&quot; on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the &quot;G&quot; (fan) terminal at the furnace.</p></div>

Q: How many string lights can be on one outlet?

• <div><p>How many string lights can be on one outlet depends on a number of varying factors, including the total wattage of your circuit, the type of lights, the energy needs of the lights, and cord specifications. It&rsquo;s better to play it safe here to protect your circuit, so figure out the max wattage of your circuit, compare that to the lights, and move on from there. Generally speaking, LED string lights require less energy than incandescent bulbs, translating to a higher number of lights per circuit. </p></div>

Q: When a light switch is off is there still power?

• <div><p>Yes, a light switch still has power even when switched off. Switches only interrupt or continue the flow of electricity into a fixture or outlet; they do not shut off the power flowing into the wire. The only way to shut off power in a light switch is to turn off the power at the circuit breaker.</p></div>
