"Carlos showed up early to my office on a Saturday morning, and finished the replacement of the electrical panel (circa 1940's) with a more up to date one with extra breakers for future expansion, all in record time. He was neat, tidy and efficient, and explained everything he was doing without being asked, in easy to understand "layman's" terms. I will use his services for any future electrical work and will gladly and enthusiastically recommend him to any one I come into contact with who asks for a recommendations for someone to help them with their electrical needs."

"Joe's Electric returned my care within minutes of me contacting them. I had a technician in my home in 1.5 hrs. Who quickly identified and fixed the problem within 35-45 minutes. They saved me from losing a whole day of work and it was worth the cost vs loss I would have incurred."

"The work was done professionally and done on schedule. Raymond the manager gave me all the information I needed before the start of the project . The communication was timely and valuable throughout the project. The main reason I hired Excellent Electric is because Raymond also made recommendations that help to reduce the cost of materials and labor. I interviewed three other companies and all gave me competitive prices, but the recommendations Raymond gave me, set Excellent Electric above the three other companies I interviewed. I will hire Excellent Electric again and recommend this company."

Electrical questions, answered by experts

A low-voltage landscape lighting system using 15 to 20 LED lights for six hours a night will average about $5 to $10 a month in electricity costs. This is considered affordable lighting for many homeowners. Most modern landscape lights use LED bulbs, but some older styles may use halogen or incandescent bulbs, which can cost up to five times more than LEDs in electrical costs.

Often, you can add extra breakers to an electrical panel. A new breaker can help with new appliance needs, and it’s a common solution when finishing an attic or basement. However, adding extra breakers can’t bring in more amps to your house, so you still need enough amp service to power everything in total. 

In the case of electrical overflow, an ungrounded outlet should trip the circuit breaker, staving off dangerous scenarios. However, this is not always the case, especially if the wires and circuit breaker are worn down or damaged in some way. Ungrounded wires melt over time as they are introduced to more and more electricity. In other words, a circuit breaker offers protection in most instances but not always, and that’s where the danger lies with ungrounded outlets.

The purpose of pigtail wiring is to connect multiple wires to a single terminal on a device. Pigtailing involves splicing a short length of wire, called a pigtail, into the multiple wires that need to be connected. The pigtail wire is then connected to the single terminal on the device, allowing all of the wires to be connected at once. This practice helps to simplify the wiring process, reduce clutter, and ensure a secure and reliable electrical connection.

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.
