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 Biden Administration banned the sale of incandescent light bulbs for general service lamps in 2023. All household light bulbs must meet a minimum efficiency of 45 lumens per watt, three times that of a standard incandescent light bulb. 

The main motivation was to improve energy efficiency and reduce carbon emissions. It is expected that banning incandescent light bulbs will cut over 200 million metric tons of carbon emissions over the next 30 years. Some bulbs are exempt, like chandelier lights and Christmas lights.

Usually, your house panel is one of the key components that must be replaced when upgrading your amp service. In many cases, you will also need to upgrade your meter base as well as other electrical components.

When wiring a switch, the power typically comes into the receptacle first. The neutral wire goes straight to the outlet, while the hot wire is split. You'll need a wire nut to splice the hot wire back to one of the receptacles, but you will also tie another wire into that same wire nut and run to the switch. That way, you can control the flow of electricity to that particular receptacle by turning the switch on and off.
