"For the past 15 years Mike from Shamrock Electric has done extensive electrical work for two homes. He is personable, reliable, knowledgeable and fastidious. Recently he returned for a smaller job and completing a delicate onyx sconce installation with the same skill and expertise. I’m always confident that the job has been done right when Mike does my electrical work. I highly recommend him. He is a pro!"

Electrical FAQs, answered by experts

No, a ceiling fan doesn’t have to be wired to a switch, but it’s often more convenient. You can use the included pull chain if your ceiling isn’t too high or install a remote module later, as they are a cheap, easy-to-install option that’ll let you control both the fan and light fixture.

While the line can't be removed, a pro can place a cap on the end to stop leaks. Contact a pro for a service call and speak with them about the related costs of either capping or removing the line altogether. Capping a gas line will cost between $75 and $150 while removing it will start at $250.

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

You can test an electric fence with a multimeter, but you’ll need to set the multimeter to the correct voltage measurement—such as alternative current (AC) or direct current (DC) and range—depending on your fence. You can find the voltage type and range in the fence’s user manual.

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.
