"Didn't show several times to a rewire job that he already had a hefty deposit on. I HAD TO SUE HIM TO TRY AND GET MY MONEY BACK. He showed up at court and tried to tell me he would pay me if I would just skip the hearing. I said I wasn't going to do that but would allow the commissioner to leave it open in case he didn't pay me as he claimed he would. The commissioner agreed to leave it open. Amos, wrote me a check...and then an hour later stopped payment! Yep, that's right. That's why I asked the commissioner to leave it open. At this point I knew he is so sketchy I had a feeling he would do something like this. So not only, do I have to try and get my deposit back but he pushed me back months on my house! Also, he is leaving to live in Spain and isn't planning on coming back. You won't see any deposit you put down with him but he will try to buy a lot of time by rescheduling, etc...His house has been for sale and he even did several recent price reductions to try and get it sold quicker! When we showed up for the 2nd hearing he tried lying but luckily I had things in writing that acknowledge he knows he owes me the money."

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
