Here at Everly Electrical Contracting we strive for excellence and take extreme pride in our work. We are not your typical service provider we are not going to come in and take advantage of our customers like most electricians do, we don't believe in lying to or cheating our customers by making them think services are required when they are not necessary.

"Hired Anthony Everly for multiple jobs related to my new home purchase. Communication was terrible, very unreliable, and I am not sure how but he billed my credit card directly at times without my approval. I have not been able to get him to provide justifications for the expenses/direct charges. I will definitively not use him again and am contemplating options to make sure the charges stop, perhaps even get refunded."

Riley was incredibly professional, punctual, and courteous throughout the entire process. He arrived right on time, explained what he was going to do, and completed the job efficiently—in just under two hours. The finished work looks excellent and met all of our expectations.

Welcome to Active Cabling & Communications, LLC. We provide the best electrical work for all our residential and commercial clients. We promise to serve our clients with the highest quality and the most convenient pricing.

"I really enjoyed the work by these Networking/Ethernet folks. A different provider had quoted me an $800-1000 project and said I needed Cat 6 cabling for ethernet, when really my existing Cat 5E was fine. All it took was ~$100 and one hour for parts and labor and I now have ethernet ports in every room that support Gigabit speed. Thanks again! Couldn't be happier with this."

Generator Install questions, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
