"Last Monday, Nov. 3, I had some major surgery done on my GENERAC generator. It was time for "Super Maintenance" and your service man did a SUPER job! His name is Joe and he did a great job servicing my machine. He arrived on time and went right to work. He changed the oil and oil filter, put in a new battery, adjusted the valves, put in a new air filter, and even cleaned the top of the generator. All this while i looked over his shoulder and asked questions, lots of questions. I am impressed with Mr. Joe. He is very knowledgeable about your products, well spoken, and easy to talk to. It took him less than an hour to complete his work, despite my constant jabbering. He's a KEEPER! Thank You Trinity, And Thank You Joe! Paul O Weller Trinity Client"

"Called Star Bright Electric for the removal of an antique chandelier that needed to be stored. They handled everything with care - cleaned the chandelier and took care of the storing it in the box. When we went over what we needed - he was able to give me an estimate over the phone (of course with pictures and dimensions of the project). They responded within a timely matter and communicated throughout the job. We are very please and highly recommend Star Bright Electric in Philadelphia. They are honest and very professional."

Generator Install questions, answered by experts

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.

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.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
