"We are new to the Milwaukee area and have remodeled several rooms in our house. The first couple of projects were a nightmare because of contractors that were slow and did not do quality work. When we hired Marty, we were hesitant because of our recent experiences. To our relief, Marty was everything we had been looking for. He was extremely responsive from the moment we contacted him and did everything he said he would in the exact time frame promised. After our inspection, our inspector said to me "Matt, I'm glad that your luck has changed after that last couple projects. Keep using this electrician, he's a professional." On top of being extremely satisfied with every aspect of Marty and how he conducts business, his pricing was about 40% less than his competitors. He's a young entrepreneur that understands the importance of keeping his word and showed me that he will do everything he can to continue his stellar reputation in Milwaukee and ensure the success of his business. I will continue to use Marty for any electrical needs I have in the future. The larger overpriced electrical companies in Milwaukee better watch out, Marty is a formidable competitor that will understandably take a lot of their business and bring the much needed "value" that milwaukeans with electrical needs have been waiting for."

"They did a great job. Very efficient and had great communication. When something came up we were made aware of it and it was also taken care in a timely fashion. Dorow's team made sure that everything was completed and met the criteria. Once the work was completed they made sure we had all documents needed for the inspector and once the inspector did the inspection and if anything needed to be added Dorow's crew made came out and added the necessary components. Overall very satisfied with a job well done!"

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.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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.

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.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.
