"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

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
