Electrical questions, answered by experts

To determine if an electrical outlet is blown, look for visible signs of damage, like burn marks or melted plastic. If not, try plugging in a few different devices to confirm that the outlet is not working. You can also use a voltage tester or multimeter to check for power—a no-reading means there's an issue. Lastly, check your circuit breaker or fuse box to see if the outlet was tripped, and if so, reset it. If none of this works, you may need to replace your outlet.

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.

Using too many Christmas lights can cause your circuit board to overload which can put your tree at risk of catching fire and potentially damage your home’s electrical grid. 

A new circuit breaker costs anywhere between $10 and $100 on average, depending on the type of circuit breaker. A standard circuit breaker is the most affordable, while a GFCI or AFCI circuit breaker will cost the most. If you’re upgrading to a higher amperage, anticipate paying closer to $250 to $350 for a 200-amp circuit breaker.

Simple moves on the same base or within a few feet will not take long, roughly three to four hours. Larger moves onto a new wall or transitioning a box from inside to outside will take 8 to 12 hours to complete. Ask your electrician for a time estimate prior to installation.
