Electrical FAQs, answered by experts

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.

Old electrical systems may have more problems than newer ones. In some cases, like if your home has aluminum wiring, it may be necessary to update your electrical system. You should also update your home’s wiring if it still has knob and tube wiring, which is considered dangerous by modern building standards. If that applies to you, get in touch with an electrical professional near you to obtain a quote.

Poorly designed and incorrectly installed outlets can create an electrical fire hazard, as do some phone chargers and adapters that plug into these outlets. However, most outlets are perfectly safe as long as they remain in working condition. Keep an eye on what you are plugging into the outlet and stay alert for signs of outlet malfunction, like sparks, burning smell, or frequent circuit tripping.

Even if you don’t have children living in your home, The National Fire Prevention Association still recommends installing tamper-resistant outlets when you’re replacing your existing outlets. 

Not only is your home likely to change hands at some point, but you may have young children over as guests. Making the switch even if you don’t currently have children living with you at the moment will help protect any future pint-sized visitors to your home.

If the fan doesn’t have a switch, connect the white wire from the ceiling to the white wire from the fan; connect the green wire to the ground wire; connect both black wires; and connect both blue wires. If yours has a switch, the white and green wires are connected the same way. However, connect the ceiling’s red wire to the light’s black wire and the ceiling’s black wire to the fan’s black wire.
