Electrical questions, answered by experts

If a 3-way switch is wired incorrectly, this can cause several issues. The most common problem is that the switches will not function properly: Either both switches won’t work, or only one will. Another issue is that one switch will trigger a short circuit, tripping the circuit breaker.

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

Yes, you can run an above-ground electrical conduit and stay within National Electrical Code safety guidelines. Just make sure you check the code requirements of your project with the local building regulations office. You should work with a local electrician to complete this type of project due to the personal safety hazards.

Electrical fixes are best handled by a licensed electrician, but it’s possible to release a wire connection on your own. Be sure to always turn off the power to the outlet at the circuit breaker before beginning your project to avoid electric shock. Carefully insert the tip of a flat screwdriver into the rectangular hole beneath the wire. Hold the outlet in the palm of your other hand. Pull out the wire as you apply pressure with the screwdriver.

Moving an electrical meter in your home depends on what your electric utility company allows. If you only want to move it a few inches, that may be no problem or only incur light fees. If you want to move it a significant distance, you may need to arrange a utility inspection and get permission, or your utility company may prevent it altogether.
