Electrical FAQs, answered by experts

You will need a permit for any electrical work that involves installing or replacing wiring, moving or installing new fixtures, switches, or outlets, hardwiring appliances or HVAC equipment, installing subpanels, and upgrading electrical service. You typically don’t need a permit to have an electrician replace an existing light fixture or electrical box. You can always call your local building department to see if your project needs a permit, but a professional electrician will be able to tell you. In most cases, your professional will pull the permits for you.

The National Electric Code states that outlets should not be spaced more than 12 feet apart, and there should be an outlet placed every 6 feet at the floor line in areas designated as living spaces. Most homes in the United States have 75 outlets, but it will depend on the amount you need based on your home's size and your needs.

You can twist the wires before using a wire nut, but it’s not necessary. Electricians often twist wires before using a wire nut, which can help secure the connection and enhance electrical contact between wires. You can decide whether or not to twist the wires beforehand, or consult a local electrician if you need  professional opinion.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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’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.
