"I had a federal pacific panel replaced. The technician and work were professional. However, I explained to the technician that I lost power in a large section of wall. After the job was complete, I found I still didn’t have power in the wall. Now I’m being told it is a separate job and cost. An explanation before having the work done about it being a separate problem and needing additional work would have been very helpful. All I’m told now is they can come out for a service call which is $212 plus whatever the issue is. This was a miscommunication error on Mr. Electrics side. I informed the tech about the problem and there was no testing on the wall afterwards. Very disappointed."

Generator Install questions, answered by experts

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.

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.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
