"I would highly recommend Naymar Electric to anyone looking for an excellent electrician. Their prices were very fair and competitive, their estimated timeframes given were more than reasonable and turned out to be accurate. I appreciated that David was readily available to answer my basic questions, as well as use his experience and creativity to wire the house in a way that would provide for future inhabitants and household configurations. He was very knowledgeable and informative, as well as creative and aesthetic, and he and his crew were hard workers that paid attention to detail and left the house easy to patch when they were through. I am so glad I went with Naymar Electric, they are now my go-to!!"

Electrical questions, answered by experts

The wrong-sized wire can lead to several safety hazards, including structural fires, surges, power outages from tripped breakers, and electrocution. It’s important to follow the American Wire Gauge system and the National Electrical Code guidelines to safely wire a home. Electrical wiring is not safe for homeowners to handle and is best left to a licensed electrician.

There are various reasons why an electrical outlet can stop working. You might have to do some detective work to understand whether it’s a problem with the attached appliance, the outlet itself, or a faulty breaker. Sometimes, old age or loose wiring are to blame; other times, it can be as simple as an overloaded circuit tripping the system and cutting power. If you’re troubleshooting doesn’t solve the mystery or repairs, or replacements are required, it’s time to call in the pros.

You should hire a licensed electrician who is insured to perform any electrical work on your home, including lighting installation. States have different requirements for licensing and certifying electricians, so use Angi’s state licensing tool to review local guidelines.

Here are a few questions to ask electricians before hiring:

  • How many years of electrical experience do you have?

  • Are you licensed, bonded, and insured?

  • Do you work with subcontractors?

  • Do you provide a guarantee or warranty on your work?

  • What is the timeline for completion?

  • How do you handle change orders?

  • Can you provide at least three customer references?

A ceiling light will usually have two or three wires: black, white, and sometimes green. Black wires are positive, or hot, while white wires are negative, or neutral. The green wire is the grounding wire. 

When you’re wiring the light, connect black to black, white to white, and green to the grounding screw.

Yes, splicing wires can cause a fire if the splicing is done incorrectly. This is why splicing wires is a task best handled by electricians. One of the most common mistakes made when splicing wires is not using a wire connector. Without a wire connector, electricity flows unsheathed and can result in a home electrical fire.
