"My experience with Apollo Electric was wonderful. I needed some normal electrical work done, and also some detailed more involved work. He handled everything with care as if it was his own home. He was very detailed oriented, neat, clean and very honest. Mike worked hard during the entirety of the job, I was very pleased and I would call him for any job I need involving electrical work for the future"

Electrical questions, answered by experts

Just like apples in a bunch, one bad outlet can cause other outlets to stop working. This is especially true if the outlets are connected in a series on the same circuit. When one outlet develops a fault, it can spread to every outlet downstream of the original.

Smart meters send the readings over a wireless wide area network (WAN) to the power company. This network allows sending small amounts of data slowly over long distances, which is perfect for smart meter readings that occur monthly. If you would prefer a smart meter, contact your power company and consider springing for the cost of replacing your electric meter.

If you need to run a wire from the meter to the breaker box, start by turning off the power using the main switch to avoid injury risks from live wires. Then, locate the ground wire from your meter and connect it to the ground bar of the breaker box. Connect the neutral wire using the same method to improve your circuit efficiency.

Next, locate the hot wires running from the main switch to the meter. To connect them to the correct terminals from meter to breaker, unscrew the nuts of the breaker hotwire terminals, insert the positive hotwire, and ensure it’s firmly attached. Finally, secure the wires with electrical tape and wire tie cables before re-securing your breaker box. Keep in mind that this process can be dangerous, so don’t hesitate to hire a local electrician.

It depends on where you live. Some cities may require a permit for electrical work, while others don’t. You’ll need to call your city’s building department to determine if you’ll need to apply for a permit or not. If a permit is required, you’ll likely have to pay a fee for it. 

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.
