When utility power fails, the system can start automatically and supply power to selected circuits or a larger portion of the home.<\/p> A complete installation may involve:<\/p> Evaluating the home\u2019s electrical demand<\/p><\/li> Selecting generator capacity<\/p><\/li> Choosing a suitable outdoor location<\/p><\/li> Installing a concrete or approved mounting base<\/p><\/li> Connecting the generator to the electrical system<\/p><\/li> Installing an automatic transfer switch<\/p><\/li> Coordinating with the existing electrical panel<\/a><\/p><\/li> Connecting the approved fuel supply<\/p><\/li> Testing startup and load transfer<\/p><\/li> Explaining basic homeowner operation<\/p><\/li><\/ul> Generator size should be based on the equipment the homeowner expects to run during an outage, not just the property's square footage.<\/p> A standby generator monitors the utility power supply through an automatic transfer switch.<\/p> When an outage occurs, the system typically follows this sequence:<\/p> The transfer switch detects the loss of utility power.<\/p><\/li> The generator starts.<\/p><\/li> The transfer switch disconnects the home from the utility supply.<\/p><\/li> Generator power is sent to the selected circuits.<\/p><\/li> The system continues operating until utility power returns.<\/p><\/li> The transfer switch reconnects the home to utility power.<\/p><\/li> The generator completes a cooldown period and shuts down.<\/p><\/li><\/ol> This automatic process allows the system to operate even when no one is home.<\/p> The exact sequence and timing depend on the generator and transfer switch model.<\/p> Homeowners can choose between systems designed to support most of the home and systems that power a limited group of essential circuits.<\/p> A whole-home generator may support major appliances, HVAC equipment, lighting, outlets, and other household systems. Actual coverage depends on generator output and the home\u2019s electrical demand.<\/p> Larger systems may use load-management controls to prevent several high-demand appliances from starting at the same time.<\/p> An essential-circuit system powers selected equipment during an outage. Common priorities include:<\/p> Refrigerator and freezer<\/p><\/li> Sump pump<\/p><\/li> Well pump<\/p><\/li> Heating equipment<\/p><\/li> Selected lighting<\/p><\/li> Internet equipment<\/p><\/li> Medical devices<\/p><\/li> Garage door opener<\/p><\/li> Kitchen outlets<\/p><\/li> Security systems<\/p><\/li><\/ul> An essential-circuit setup may be appropriate when the homeowner does not need every appliance operating at once.<\/p> A generator that is too small may overload, shut down, or fail to support the equipment connected to it. A generator that is larger than necessary may add cost without providing a practical benefit.<\/p> Generator sizing should consider:<\/p> Heating and cooling equipment<\/p><\/li> Well pump demand<\/p><\/li> Sump pump demand<\/p><\/li> Refrigerators and freezers<\/p><\/li> Electric water heating<\/p><\/li> Cooking appliances<\/p><\/li> Lighting and outlet circuits<\/p><\/li> Medical equipment<\/p><\/li> Home office equipment<\/p><\/li> Garage doors<\/p><\/li> Future electrical needs<\/p><\/li> Equipment starting loads<\/p><\/li><\/ul> Motors and compressors often require more power when they start than they use while running.<\/p> Our electricians review the expected loads and explain which systems the proposed generator can support.<\/p> The transfer switch is one of the most important parts of a standby generator system. It separates the home from the utility supply before generator power is introduced.<\/p> This prevents backfeeding, which can endanger utility workers, damage equipment, and create fire or shock hazards.<\/p> Transfer equipment may be configured to power:<\/p> The entire electrical panel<\/p><\/li> A dedicated emergency panel<\/p><\/li> Selected circuits<\/p><\/li> Managed high-demand loads<\/p><\/li><\/ul> The transfer switch must be compatible with the generator, electrical service, and intended operating plan.<\/p> The condition and configuration of the electrical panel can affect a generator installation.<\/p> Before work begins, our electricians evaluate:<\/p> Main service size<\/p><\/li> Panel condition<\/p><\/li> Breaker arrangement<\/p><\/li> Available space<\/p><\/li> Grounding and bonding<\/p><\/li> Existing high-demand equipment<\/p><\/li> Previous electrical modifications<\/p><\/li> Transfer switch location<\/p><\/li> Circuit priorities<\/p><\/li><\/ul> An older panel does not automatically require replacement. The recommendation should be based on its condition, capacity, compatibility, and available installation options.<\/p> When needed, Harris can provide electrical panel service<\/a> as part of the broader project.<\/p> Portable generators can provide temporary power, but they must be connected and operated correctly.<\/p> Never connect a portable generator to a household outlet. This practice, sometimes called backfeeding, can energize utility lines and create serious shock, fire, and equipment risks.<\/p> A safer setup may include:<\/p> A properly installed transfer switch<\/p><\/li> A generator inlet<\/p><\/li> Approved outdoor-rated connections<\/p><\/li> Correctly sized cords<\/p><\/li> Selected emergency circuits<\/p><\/li> Carbon monoxide precautions<\/p><\/li><\/ul> Portable generators must be operated outdoors and away from doors, windows, vents, garages, and occupied areas.<\/p> Follow manufacturer instructions for placement, fueling, grounding, maintenance, and operation.<\/p> A standby generator may fail because of a battery problem, fuel issue, control fault, damaged connection, transfer switch problem, or internal equipment failure.<\/p> Schedule generator repair when:<\/p> The generator will not start<\/p><\/li> The system starts but does not supply power<\/p><\/li> The generator shuts down unexpectedly<\/p><\/li> Warning lights or fault codes appear<\/p><\/li> The automatic transfer switch does not operate<\/p><\/li> The weekly exercise cycle does not run<\/p><\/li> The generator sounds unusual<\/p><\/li> Fuel odors are present<\/p><\/li> The battery repeatedly loses charge<\/p><\/li> Breakers trip when generator power is active<\/p><\/li> The system leaks oil or coolant<\/p><\/li> Power fluctuates during operation<\/p><\/li><\/ul> Do not remove covers or reach into operating equipment. Generator systems contain electrical, mechanical, and fuel-related hazards.<\/p> Urgent problems involving sparking, overheating, damaged wiring, or unstable power may require an emergency electrician<\/a>.<\/p> Routine maintenance helps reduce the chance of a generator failing during an outage.<\/p> Maintenance needs vary by model and operating history but may include:<\/p> Checking the battery<\/p><\/li> Inspecting electrical connections<\/p><\/li> Reviewing fault history<\/p><\/li> Checking fluid levels<\/p><\/li> Inspecting belts and hoses<\/p><\/li> Replacing filters<\/p><\/li> Checking the enclosure<\/p><\/li> Testing the transfer switch<\/p><\/li> Confirming the exercise cycle<\/p><\/li> Running the system under load<\/p><\/li> Inspecting for corrosion, leaks, and damage<\/p><\/li><\/ul> A generator that runs only during a brief weekly exercise cycle can still develop problems between outages.<\/p> Service should be based on manufacturer guidance, operating hours, environmental exposure, and system age.<\/p> Repair is not always the best option for an older or unreliable generator.<\/p> Replacement may be appropriate when:<\/p> The system has repeated failures<\/p><\/li> Major parts are no longer available<\/p><\/li> The generator cannot support current household needs<\/p><\/li> Corrosion has damaged the enclosure or connections<\/p><\/li> Repair costs are increasing<\/p><\/li> The transfer equipment is outdated<\/p><\/li> The generator has sustained storm or flood damage<\/p><\/li> The system cannot operate safely<\/p><\/li> The homeowner wants broader outage coverage<\/p><\/li><\/ul> Before recommending replacement, our electricians assess the generator, transfer equipment, panel, and expected power needs.<\/p> Generators can provide dependable backup power, but incorrect use can create serious risks.<\/p> Portable generators produce carbon monoxide. They should never be operated inside a home, garage, basement, shed, crawlspace, or enclosed porch.<\/p> Do not operate portable equipment in standing water or exposed to rain. Use only approved weather protection that does not trap exhaust.<\/p> Never plug a generator into a household receptacle. Use approved transfer equipment installed by a qualified electrician.<\/p> Hot generator components can ignite spilled fuel. Follow manufacturer instructions and keep fuel in approved containers.<\/p> Connect only equipment the generator can support. Overloading may damage the generator, appliances, cords, and connected wiring.<\/p> Generator components can become hot during operation. Do not remove covers or attempt repairs while the system is running.<\/p> Storms can damage more than the utility system. Lightning, wind, flooding, and voltage fluctuations may affect generators, transfer switches, panels, wiring, and connected appliances.<\/p> After severe weather, watch for:<\/p> A generator that does not start<\/p><\/li> Damaged outdoor equipment<\/p><\/li> Water near electrical components<\/p><\/li> Loose conduit or wiring<\/p><\/li> Burn marks<\/p><\/li> Fault codes<\/p><\/li> Unusual sounds<\/p><\/li> Failed transfer operation<\/p><\/li> Appliances that do not work correctly after power returns<\/p><\/li><\/ul> Do not approach generator or electrical equipment surrounded by water.<\/p> Whole-home surge protection<\/a> may help reduce damage from certain voltage events, but it does not eliminate every storm-related risk.<\/p> Generator work should account for the equipment, electrical system, fuel source, and household power needs.<\/p> We identify which appliances and systems the homeowner wants to operate during an outage.<\/p> Our electrician checks the panel, service size, circuit arrangement, grounding, and available installation options.<\/p> For a new installation, we review generator capacity, location, transfer equipment, and connection requirements.<\/p> For a repair, we inspect the existing generator, transfer switch, wiring, controls, and visible fault conditions.<\/p> We explain the proposed installation or repair, expected generator coverage, and any related electrical work.<\/p> Our electricians install or repair the approved electrical components and coordinate the system with the home\u2019s panel and transfer equipment.<\/p> We test startup, transfer, connected circuits, and return to utility power. For new systems, we also explain basic operation and monitoring.<\/p>","content_3":" Power outages in Delaware may be caused by thunderstorms, tropical systems, winter weather, fallen trees, high winds, equipment failures, and utility work.<\/p> Homes in Wilmington and older parts of New Castle County may have limited panel space, detached garages, or electrical systems that have been changed over several decades.<\/p> Properties in Newark, Bear, and Middletown may have central air conditioning, electric appliances, home offices, and other loads that affect generator sizing.<\/p> Homes in Smyrna, Dover, and less densely developed parts of Kent County may rely on well pumps, sump pumps, septic equipment, detached buildings, or longer private electrical runs. Loss of power can affect water, drainage, heating, refrigeration, and communication at the same time.<\/p> Our electricians evaluate the home and its essential systems before recommending a generator plan.<\/p> A generator is one part of a broader outage plan.<\/p> Homeowners can prepare by:<\/p> Keeping the generator area clear<\/p><\/li> Scheduling routine maintenance<\/p><\/li> Confirming the exercise cycle runs<\/p><\/li> Knowing which circuits receive backup power<\/p><\/li> Keeping portable-generator fuel stored safely<\/p><\/li> Testing carbon monoxide detectors<\/p><\/li> Keeping flashlights and batteries available<\/p><\/li> Protecting sensitive electronics<\/p><\/li> Keeping generator documentation accessible<\/p><\/li> Addressing fault codes before severe weather<\/p><\/li><\/ul> A generator should not be assumed to be ready simply because it worked during the last outage.<\/p> Generator installation and service require coordination between the generator, transfer equipment, panel, wiring, and household loads.<\/p> Harris Plumbing, Heating, Air & Electric provides:<\/p> Standby generator installation<\/p><\/li> Generator repair and maintenance<\/p><\/li> Transfer switch installation and service<\/p><\/li> Generator load evaluations<\/p><\/li> Electrical panel coordination<\/p><\/li> Troubleshooting for failed automatic operation<\/p><\/li> Service throughout New Castle and Kent Counties<\/p><\/li>Home Generator Services We Provide<\/h2>
