"Electrician had professional appearance and work ethic. Job was not easy due to the new RG6 cable was required to be installed in the flat roof area of the home which is a very confined space to maneuver. Arrived on time as promised, but unfortunately the cable used was not adequate to transmit the new Spectrum digital signal and the following day I had to have the newly installed cable (which was a copper cladded RG6 cable) replaced by a steel cladded RG6 cable in order to receive the Spectrum signal. I attempted to alert the electrician that due to the recent change of Spectrum from an analog signal to a digital signal on April 17th 2018 that he needed to use a higher quality RG6 cable or he would continue to have unsatisfied customers. Electrician has failed to return my call which is unfortunate for him as I think his work was excellent, but his future cable installation jobs may be rated less than excellent if the quality of cable used is not resolved."

Generator Install questions, answered by experts

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.

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. 

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
