Electrical questions, answered by experts

Ultimately, the best device depends on what you’re measuring. A voltmeter only measures volts, while a multimeter measures volts, current, resistance, humidity, and possibly much more, depending on the model. If you think you’ll need to measure more than volts, consider investing in a multimeter so you have a tool that can help you with various household projects.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

Your outlet should be a ground-fault circuit interrupter (GFCI). These outlets will cut power off in the case of an electrical fire, keeping your home and family safe. Extension cords can also be GFCIs. A local electrician can replace older outlets with GFCIs, if necessary.

You should never plug a normal 120v appliance into a special 240v outlet, as it can quickly burn out the appliance. This will cause irreparable damage to the appliance and, in worse case scenarios, cause damage to your circuit breaker. Check your appliance’s rating before plugging it into a 220v outlet to avoid electrical disaster.

Common signs of faulty electrical wiring include frequent circuit breaker trips, flickering or dimming lights, burning smells near an outlet, buzzing or humming sounds, electrical shocks or tingles when handling outlets of appliances, and hot or discolored outlet switches. If you notice one or more of these signs, hire a licensed electrician for an average cost of $50 to $100 per hour to diagnose and make necessary repairs.
