"WB Lightning Rods did an excellent job installing lightening rods on our home. The owner stayed onsite the entire time to supervise the work. He took extra care to plan the rod and cable placement to ensure the proper protection and retain the aesthetics of our home. His crew were knowledgeable, polite, neat and efficient. We could not be more pleased with the results."

Electrical questions, answered by experts

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

No. When applied properly, electrical tape is designed to be an insulating material with high resistance to electricity. It can reinforce electrical connections and act as a safeguard to help ensure the electrical current stays within its designated pathways. However, it’s important to note that it can break down over time and you should never use it as a replacement for electrical wire caps.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

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.

No, it doesn’t matter which of the two wires goes on each of the two switch terminals. Just be sure to put the ground wire in the correct terminal. The ground wire is either green, bare copper, or green with a yellow stripe. The other wires are hot wires and are typically black. They can be used interchangeably.
