Hi, I’m Klaus. I’ve been an electrician for over 20 years and a Master for 17, specializing in residential and commercial installations, refits/remodels and troubleshooting. I previously ran a small electrical business for ten years but was forced out with the economic collapse of 2008. We’re baaaaack! Here at Resolute Electric we can help you out with all of your electrical projects and problems. From replacing that atrocious light you’ve always hated to wiring your new house or business, we’re ready to power your needs. We offer free estimates and would love to put eyes on what you need accomplished. No job is too small because you need it taken care of and that’s what we’re here for. Ask us lots of questions and don’t worry, there are no dumb ones. If you’re on the Delmarva Peninsula rest assured, when we show up you’ll have a licensed and insured electrician who will make your concerns the only focus and number one priority.
"It was 2 days before Thanksgiving and my power kept flickering on and off. I had the power company out to my home who informed me that the box where the main power comes in...under the meter needed to be replaced and I had to call an electrician to do that. I had been coordinating with another electrical company while I was at work, to have someone come out that day. Unfortunately despite their efforts to find an available electrician, by 3:00 p.m. they were still non-committal. So in desperation, I decided to use Angie's list for the first time. That is how I came upon Resolute Electric. Contact was made within 5 minutes, and Clause who is either the manager or the owner was at my home within 1 hour to complete an assessment and quote me a price. He had one of his electricians at my house within another hour and the work was completed by 8:00 p.m. . He did not charge me any extra for the late hour of service simply because he was more concerned about our safety then making or taking advantage of our desperation. Both Clause and Randy displayed a level of professionalism and work ethic that you don't come upon very often these days. That being said, I felt it was important that they're excellence be acknowledged. I can't thank them enough."

Generator installations FAQs
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
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.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
