Electrical questions, answered by experts

On average, it takes from four to eight hours to replace an outside electrical meter box, not including rewiring. It will take a few more hours if the project requires pros to do any rewiring work. Consult your local electrician about a time estimate for your specific project.

A low-voltage landscape lighting system using 15 to 20 LED lights for six hours a night will average about $5 to $10 a month in electricity costs. This is considered affordable lighting for many homeowners. Most modern landscape lights use LED bulbs, but some older styles may use halogen or incandescent bulbs, which can cost up to five times more than LEDs in electrical costs.

Yes. You should always turn off the power to the work area before beginning, use a voltage tester to ensure it’s off, and wear protective gear, such as insulated gloves or safety glasses, to prevent risk of injury. Proper wiring and grounding techniques are also necessary to make sure the job is done right the first time and won’t harm any future homeowners. 

Yes, a water leak poses a major fire risk at your home because water is a conductor of electricity. Water that comes into contact with sparks or electrical wires can instantly ignite flammable materials. Additionally, any type of exposure to water can cause wires and other electrical components within your home to corrode. When assessing categories of water damage, it's important to know that even a small amount of moisture near wiring could cause sparks that lead to a fire.

Using a wire stripper/cutter, strip about 1/2 inch to 1 inch of sheathing from electric wires, depending on the application. A self-adjusting wire stripper/cutter works best, but a standard wire stripper/cutter with holes for different gauges of wire works as well to cut and strip away the sheath without damaging the copper wire inside.
