Electrical questions, answered by experts

While it’s not possible to put a main breaker in a main lug panel, it’s possible to convert a main lug to a main breaker. Converting to a main breaker panel offers increased safety, simplified control, compliance with building codes, and adaptation to changing electrical needs, especially when adding new circuits or upgrading the system.

A GFCI outlet can be 15A or 20A. The average American home power outlet is 15A.

This depends on how many outlets you have and the current status of your electrical system. The cost to ground an outlet clocks in at $75 to $480 per outlet, so multiply that by the number of outlets in your home to arrive at a rough estimate. However, this is for simple projects with no obvious issues with the system. Your final bill could vary widely from your calculations.

Often, you can add extra breakers to an electrical panel. A new breaker can help with new appliance needs, and it’s a common solution when finishing an attic or basement. However, adding extra breakers can’t bring in more amps to your house, so you still need enough amp service to power everything in total. 

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.
