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."

Ready to cut the cord, and rabbit ears aren?t cutting it? Cables hanging all over your house, and you want them to disappear? WiFi just doesn?t reach upstairs? You?ve come to the right place! My services include: TV and FM antenna installation and repair, including in attics; old school cable fishing and concealment; installation and repair of coaxial, Ethernet, telephone, speaker, and other low voltage wiring, including repurposing existing cabling; TV wall mounting and cable concealment, especially difficult or unusual locations; limited satellite dish installation, repair, and removal, including Free-To-Air (FTA) dishes. (Sorry, no large C-band dishes, no warranty work on subscription service equipment.) I'm not an equipment dealer, so I won't be trying to sell you anything. I can provide a few items, as a convenience (e.g., antennas, bulk cable), but I?m ready to work with, or advise you on the purchase of your own equipment (e.g., routers, security cameras).

"Ken is a terrific worker and knowledgeable problem solver who took on my old house and my cramped crawl space without even a hint of hesitation or complaint. He worked efficiently and without a pause for more than 10 hours to get a job done in record time----it was much more involved than we thought, and he persisted and got it done, and done right. Thank you Ken! He's a real rarity amongst workmen, absolutely thorough, trustworthy and good natured in the face of all difficulties! A real gem, I'm so glad I hired him!"

Generator Install questions, answered by experts

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.
