When a summer storm or a winter ice event takes down the power, a generator is the difference between a minor inconvenience and days without heat, refrigeration, or a working sump pump. Jab and Son Services sizes, installs, and connects backup power systems for homes across Northern Virginia and nearby parts of Maryland and DC, so your family stays comfortable and safe when the grid goes quiet.

What Backup Power Covers

We work with standby generators that start automatically the moment utility power fails, as well as manual and portable setups tied in through a proper transfer switch. A standby system runs on natural gas or propane and can power your whole home or just the circuits that matter most, like the furnace, fridge, well pump, and a few outlets. We handle the electrical side from start to finish: transfer switch, panel connection, load calculation, and safe wiring.

Signs a Generator Is Worth It

If your street loses power several times a year, if you rely on a sump pump to keep a basement dry, or if anyone in the home depends on medical equipment, backup power stops being a luxury. Homeowners with well water, home offices, or long outages after storms tend to feel the loss the hardest. If you have been running extension cords from a portable unit through a cracked window, there is a safer, code-compliant way to do it.

What Installation Involves

We begin with a load calculation to match the generator to what you actually need to run. From there we install a transfer switch that isolates your home from the utility line, wire the generator into your panel, and coordinate the gas or propane connection. Portable-friendly setups get an inlet box and interlock so you never have to backfeed a circuit. Once wired, we test the transfer under real conditions.

Safety and Code Considerations

The single most important rule is a proper transfer switch or interlock. Backfeeding a generator into an outlet can send power onto utility lines and endanger the crews working to restore service. Code also governs clearances, grounding, and how the generator ties into the panel. As a licensed and insured Master Electrician, Abraham makes sure the installation passes inspection and keeps everyone safe.

Backup power is not the place for shortcuts. Abraham brings 14 years of hands-on experience and explains your options in plain terms, from a few essential circuits to whole-home coverage, with pricing laid out before the work starts. We do clean, careful installs and stand behind them. When the next outage hits, you will be glad the wiring was done right.

Good to know

Frequently asked questions

What size generator do I need?
It depends on which appliances and circuits you want to run. We perform a load calculation so you buy the right size rather than paying for capacity you will not use.
What is a transfer switch and why do I need one?
A transfer switch safely disconnects your home from the utility before generator power flows in. It prevents dangerous backfeed and is required by code.
Can a generator power my whole house?
A properly sized standby unit can. Many homeowners instead cover essentials like heat, refrigeration, and the sump pump to keep costs reasonable.
Should I choose a standby or a portable generator?
Standby units start automatically and run on gas or propane, while portables cost less but need manual setup. We help you weigh convenience against budget.
Is it safe to plug a generator into a wall outlet?
No. That is backfeeding, and it can electrocute utility workers and damage your equipment. An inlet box with an interlock is the safe method.
Do you handle the gas hookup?
We manage the electrical installation and coordinate the fuel connection so the whole system works together safely and reliably.
How long can a standby generator run?
On natural gas it can run for days as long as the supply holds. Propane runtime depends on the size of your tank.
Will the installation pass inspection?
Yes. We install to current code and to manufacturer specifications so the system is safe and ready for inspection.
