"C.J. was very professional, very skilled and did an excellent job installing two heavy chandeliers - one to replace an old one and one to be moved to center over the kitchen table. I was amazed at how he went about his job; he was very precise and very careful to get the job done right and to our satisfaction. I was also very impressed with this young man who not only did a great job but did it all my himself, prepped the site and cleaned it after the work was done. I would recommend him for any electrical job. Theresa A."

Electrical questions, answered by experts

No. Blue wires and black wires are different. Even though both are used as hot wires, they serve different functions. Black wires are far more common in residential properties. They are always hot, can be positive or negative, and usually carry electricity from a power source to an outlet. Blue wires have a specialized usage in residential properties, generally as traveler wires, and are more common in commercial properties.

Local building codes typically require conduit around exterior wiring. Conduit protects the wire from moisture, extreme temperatures, sun exposure, and harsh weather conditions to prolong its lifespan. When a wire is worn out, it can be dangerous as the risk of electric shock or fire increases.

Yes, but our analogy with the water hose doesn’t really work here. You see, electrical flow isn’t constant: It ebbs and flows like waves, coming in pulses of power. Hertz measures the rate of change in the flow of electricity, or how often it ebbs and flows. For example, 60Hz means that the electrons pulse through wiring 60 times per second. When they are pulsing, they’re in a brief retreat. Almost all United States equipment is rated for 60Hz.

You can identify the amperage and voltage of most outlets by their slot shape and prong count. Buttons, switches, and USB ports also give it away. Look for printed labels like "TR" or "GFCI," and compare your outlet to the labeled images above.

Even if you don’t have children living in your home, The National Fire Prevention Association still recommends installing tamper-resistant outlets when you’re replacing your existing outlets. 

Not only is your home likely to change hands at some point, but you may have young children over as guests. Making the switch even if you don’t currently have children living with you at the moment will help protect any future pint-sized visitors to your home.
