Electrical questions, answered by experts

You should never wire neutral and ground wires together at a light switch. Not only is it unsafe, but it’s also incorrect. The neutral and ground wires perform separate functions in an electrical circuit and should never be swapped or wired together at a light switch, light, or outlet. 

There are several signs to look for to determine if a switch is bad. For one, if you notice that the switch is loose, it's good to replace it before it becomes worse. Other signs of failure include a switch that feels excessively warm or hot, a buzzing sound, any occurrence of sparks while operating the switch, flickering lights, or just a general failure to turn the light on or off. 

If the outlet is a GFCI model, this is normal since these outlets have their own breakers that shut off when they encounter a problem—just hitting the reset button should solve the issue. Otherwise, the outlet could have bad wiring, or your circuit breaker could be having issues. If the issue started out of nowhere and is not on a GFCI outelt, it’s best to contact an electrician to diagnose the issue.

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.
