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

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
