Electrical questions, answered by experts

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

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.

If you encounter any issues or feel unsure about your abilities, stop immediately and contact a licensed electrician for help. It's better to be safe than sorry when it comes to electrical work, as mistakes during the wiring process can be hazardous to your home and personal safety.

Moving an outlet usually costs between $25 and $300. The amount you'll pay depends on the type of outlet and the condition of the walls in your home. Exposed walls without drywall and insulation are the easiest for electricians to work on, but finished walls that will require repair afterward can drive up the cost.

An AC disconnect, also known as a switch box or fuse box, is a safety switch that allows the AC’s electrical supply to be turned off from the outside, usually done by a mechanical contractor coming to work on your unit. The box is protected from the weather by a cover or may be designed as a pull-out unit. Your local code determines where the AC disconnect must be mounted, but it's usually close to your outdoor AC unit.
