Residential Automatic Standby Generators In Limeport, PA
A Standby Generator That Powers Your Whole House On Its Own, Wired Right The First TimeSized For Your Real Load, Installed With A Transfer Switch, & Backed By A Lifetime Workmanship Warranty
When the power goes out, an automatic standby generator in Limeport, PA brings it back within seconds—no cords or manual switches needed. A whole-home backup power system monitors the grid and starts on its own the moment it fails. Then it returns power when utility service is restored.
Getting that reliability comes down to the wiring and the sizing. A generator that’s too small will overload, and a sloppy transfer switch is a safety problem. That’s why at Shafnisky Electric, we handle the full generator installation: load calculation, pad, gas line coordination, transfer switch, and final testing.
We’ve wired backup power across the Lehigh Valley for 38 years, and we stand behind every connection we make.
How Shafnisky Electric Installs Automatic Standby Generators In Limeport, PA
A clean standby generator install follows a set order so nothing gets skipped. Here’s how the work progresses from the first visit to the first test.

Load Calculation & Sizing
We start by measuring what your home actually draws. That means adding up the power usage of your heating, well pump, appliances, and anything else you want running during an outage.
This step determines the generator size because an undersized unit will overload and shut down. Getting the number right up front means the generator carries your real load without strain, every time the grid drops.
Pad & Placement
Next, we set a level pad and place the unit where code and clearance allow. Placement affects exhaust routing, noise, and access for future service. We keep it clear of windows and doors and close enough to your gas line and panel to keep runs efficient.
A proper pad keeps the generator level and stable for the life of the unit.
Transfer Switch Wiring
Then we wire the automatic transfer switch, the piece that makes the system automatic. It disconnects your home from the grid during an outage, connects it to the generator, and reverses when utility power returns.
This isolation protects utility crews and prevents back-feed. Done right, the switchover happens in seconds with no action from you.
Startup & Testing
Finally, we commission the unit and run it under load. We confirm the generator starts on a real outage signal, carries your circuits, and hands power back cleanly. We walk you through the weekly self-test and maintenance schedule before we leave.
You get a system that’s been proven to work, not just installed and hoped for.
Choosing The Right Automatic Standby Generator For Your Limeport, PA Home
A few decisions shape your generator project. Here’s how to think through the ones that matter most.

Picking A Generator Brand
We install and wire Generac, Kohler, Caterpillar, and Cummins units. Each brand has strengths in output range, noise level, and warranty terms. The right pick depends on your load, your budget, and how the unit fits your property. We match the model to your home rather than pushing a single line for everyone.
Sizing For Essentials Or The Whole House
You can back up a few key circuits or the entire house. A smaller unit covers the well pump, fridge, furnace, and some lights. A larger unit runs central air and everything at once. Your choice depends on your budget and how much of normal life you want during a long outage. We run the load numbers either way.
Choosing A Fuel Source
Standby generators run on natural gas or propane. Natural gas ties into your utility line and never needs refilling. Propane works well where there’s no gas service, though it draws from a tank you keep filled. We help you weigh what’s already at your home against what each fuel means for runtime during a longer Limeport, PA outage.

Home Generator Questions From Limeport, PA Homeowners
Here are the questions we hear most from homeowners weighing a standby generator in Limeport, PA.
Can I stay in my home during the rewire?
A: In most cases, yes. We work through the house in stages and keep power available to areas we aren't actively rewiring. For larger projects, we'll map out which circuits go offline and when, so you know what to expect each day.
Can you add smart wiring to an existing house?
A: Yes, we retrofit smart home wiring into existing homes across the area. We fish low-voltage wiring through existing wall and ceiling cavities to limit disruption. Access varies by house, so we assess the layout first and plan runs that minimize drywall work.
Can You Coordinate With My Gas Or Fuel Company When Installing My New Generator?
We always recommend a company we trust to complete the gas or fuel section of a generator installation, but we leave the final decision up to the customer. If you choose to work with an outside company, you would be responsible for scheduling gas and fuel services.
Can You Upgrade My Knob & Tube Wiring?
Absolutely! Although the process can be quite tedious and time-consuming, we are experts at upgrading Lehigh Valley homes and businesses from knob and tube wiring to safer, more efficient electrical systems.
Do I Need To Upgrade My Electrical Service To Have An EV Charger Installed?
With the invention of smart panels and load-shedding panels, upgrading your entire electrical system may not always be necessary. We have the expertise to prioritize your electrical service using smart home technology to assign priority levels, such as priority 3 for water heaters, priority 2 for cooking appliances, and priority 1 for electric vehicle chargers. This ensures that your car is ready for work tomorrow without overwhelming your electrical system.
Do you install automatic standby generators throughout Lehigh County, PA?
Yes. We install and wire residential standby generators in Limeport, PA and across Lehigh County, PA. Our two-state footprint covers the wider Lehigh Valley and North Jersey. Use the form below with your zip code, and we'll confirm coverage and schedule a sizing visit for your home.
Do You Offer Any Other Services Other Than Electrical Such As Plumbing Or HVAC?
No, we do not. As a company focused on providing our customers with top-tier services, we choose to focus solely on electrical solutions for the Lehigh Valley and Northern New Jersey. Be sure to check back later; we are always expanding the scope of our skill set.
Do You Provide Your Own Trenches Or Excavation Equipment?
We always use in-house equipment when we take on electrical projects that require trenching or excavation services. If we need an extra set of hands or vehicle, we have a secondary trusted crew of professionals from the Lehigh Valley area on standby, ready to give assistance.
Does the rewire include a code inspection?
A: Yes. We bring the system up to current code and coordinate the inspection as part of the project. Once the new wiring and panel pass inspection, you have documented code compliance and a system ready to meet modern electrical safety demands. You can explore more of our work across the region on ourservice areas overview.
How Do I Know If I Need After-Hour Emergency Electrical Service?
Not sure? Give us a call! We will troubleshoot over the phone for free to save you money and time, and we can even suggest options before our workers come in the morning during normal working hours. Our emergency services are available 24 hours a day, 7 days a week.
How do I know my house needs to be rewired?
A: Signs point to a rewire when you see ungrounded two-prong outlets, breakers that trip often, dimming lights, or warm outlet covers. Older wiring types like knob and tube or cloth-insulated conductors are strong reasons to plan a complete home electrical replacement. We assess the system and tell you what your house actually needs.
How does an automatic standby generator actually work?
An automatic standby generator starts on its own within seconds of a power outage and shuts down when utility power returns. It sits permanently outside on a pad, connected to your gas line and an automatic transfer switch.
You don't touch anything during an outage. The system senses the drop, starts, and automatically restores power to your circuits.
How High In The Air Can You Install, Replace, Or Rewire Signs & Lighting In North Jersey & PA?
When it comes to installing billboards, signs, and lighting designs high in the air, there’s no limit to how high we will work. We have worked over 120 feet in the past but have the equipment to go further.
How long does a generator install take?
Most residential standby generator installs finish in one to two days of on-site work. Sizing, permits, and equipment delivery happen before that. The install itself covers the pad, gas line coordination, transfer switch wiring, and startup testing. Larger whole-house systems with longer runs tend to be on the higher end of that range.
How long does a smart home wiring job take?
A: Timing depends on scope and whether it's new construction or a retrofit. A basic lighting control setup can be completed quickly, while a fully structured wiring backbone across a whole house takes longer. We provide a timeline for your scope so you know what to expect before we begin.
How long does whole house rewiring take?
A: Most whole-house rewires run from a few days to about two weeks. The timeline depends on the home's size, the number of circuits, and the accessibility of the walls. We give you a schedule up front and keep you posted as the work moves room to room.
I Have Knob & Tube Wiring, Do I Need To Rewire My Entire Lehigh Valley Home?
While it may not be mandatory in the state of Pennsylvania to upgrade from knob and tube wiring. It is essential to comply with local municipality codes when it comes to electrical requirements. Rather than requiring your entire home to be updated, bringing it up to code is often sufficient.
Natural gas or propane, which is better?
Natural gas is the simpler option when your home already has a utility gas line, since it never needs refilling. Propane is the right pick where there's no gas service, drawing from a tank you keep filled. We look at what's already at your home and how long you need runtime, then help you decide.
What brands do you use for home automation?
A: We build lighting control and automation on Lutron and Leviton equipment. These are established brands with real support and long-term parts availability. Using name-brand gear means your keypads, dimmers, and scenes stay serviceable years down the road.
What drives the cost of a whole house rewire?
A: The biggest factors are your home's square footage, how many circuits need replacing, how easy the walls are to access, and whether the panel needs upgrading. Homes with finished walls or tight cavities take more labor to route wire. We scope the work in person and explain what's driving the number.
What drives the cost of generator installation?
The main cost drivers are generator size, fuel type, transfer switch complexity, and the distance from the unit to your gas line and panel. Whole-house units cost more than essential-circuit setups. Longer gas and electrical runs add labor. We give you a written scope so you can see exactly what each piece of the install includes.
What drives the cost of smart home wiring?
A: The main cost drivers are home size, how many device locations you want, wall access, and how deep you take lighting control. A few smart switches cost far less than a full structured backbone with lighting scenes. We walk your home and give you a scope before any work starts.
What is structured wiring?
A: Structured wiring is low-voltage cabling that all runs back to one central panel. Every network drop, control line, and audio run terminates at a single labeled hub. This layout makes troubleshooting and adding devices much easier, since everything connects in one organized place rather than at scattered junctions.
What size generator do I need for my home?
The right size depends on your home's electrical load, not its square footage. We add up everything you want running during an outage, like your well pump, furnace, fridge, and central air.
That total sets the generator's output rating. Backing up essential circuits needs a smaller unit than running the whole house at once.
What Size Generator Should I Have Installed?
Our electrical experts determine the perfect size generator for your home or business based on many individual factors. These factors include the size of the space needing energy, which appliances or systems will run off the generator, local permitting regulations and code requirements, and so on.
What warranty comes with smart home wiring?
A: Every smart home wiring project carries a 2-year warranty on all work plus a lifetime warranty on our workmanship. The 2-year warranty covers the work broadly, and the lifetime workmanship warranty covers how it was installed. If something we wired fails, we come back and make it right.
What warranty comes with the installation?
Every generator installation carries a 2-year warranty on all work plus a lifetime warranty on our workmanship. The workmanship warranty covers the wiring, connections, and transfer switch setup we perform, for as long as you own the system.
The generator itself carries its own manufacturer warranty from Generac, Kohler, Caterpillar, or Cummins.
What warranty covers the rewiring work?
A: Every whole house rewiring project carries a 2-year warranty on all work plus a lifetime warranty on our workmanship. The 2-year term covers the job broadly, and the lifetime coverage supports the quality of the work. Both are current, active warranties on our residential work.

If you ever have doubts about your electrical system's safety or integrity, call us! Our quotes are quick and free, and will get to the bottom of your electrical problems with long-term solutions. It never hurts to be informed and prepared!
Why is wired smart home wiring better than wireless?
A: Wired systems stay faster and more stable than wireless alone. Structured cabling carries lighting, control, and network signals without the dropouts that happen when too many devices share Wi-Fi. Wireless still has a place for some devices, but a hardwired backbone keeps the whole system dependable, especially in larger homes.
Will rewiring tear up my walls?
A: We keep wall openings to a minimum by fishing new wire through existing wall and ceiling cavities. Some access points are unavoidable on a full rewire. We patch those spots as part of the job and coordinate the finish so your home isn't left with open drywall.
