When the power goes out, most homeowners do the same thing: run extension cords everywhere, try to power too much, or worse… attempt a dangerous shortcut. There’s a SAFE way, and an UNSAFE way to power your home with a portable generator.
Let’s clear this up, so you can keep the lights on safely.
What NOT to Do
Before we talk about the right setup, here’s what to avoid:
- ❌ Do NOT backfeed your house through an outlet
(This is illegal, dangerous, and can kill a utility worker) - ❌ Do NOT run your generator in the garage
(Carbon monoxide risk—this is deadly) - ❌ Do NOT overload your generator
(You’ll trip breakers or damage equipment) - ❌ Do NOT rely on extension cords long-term
(Messy, limited, and not practical)
The Right Way to Connect a Generator
The safe, permanent solution is a portable generator hookup system, which includes:
- A generator inlet box (installed outside your home)
- A transfer switch or interlock kit
- A proper connection to your electrical panel
This allows you top lug your generator in outside, safely send power into your panel, and run essential circuits without extension cords

Common Questions:
What Does It Cost?
Most homeowners spend $600 – $1,200 for a generator inlet + interlock setup. Transfer switch setups can be slightly higher, that’s still a fraction of the cost of a standby generator—and gets you reliable backup power.
What Size Cord Do I Need?
This depends on your generator, but most setups use:
- 30-amp cord → most common for homeowners
- 50-amp cord → for larger generators
We match the inlet, breaker, and cord to your generator so everything works safely together.
What Size Generator Do I Need?
For most homes:
- 3,000–5,000 watts → basics (fridge, lights, small loads)
- 5,000–7,500 watts → more comfortable coverage
- 7,500+ watts → can handle multiple major systems
We help you plan this so you don’t overspend—or come up short.
Can a Portable Generator Power my Whole House?
Usually? No. This is the primary downside to choosing a portable generator over a classic standby generator. They don’t have the same amount of power.
Most homeowners power their refrigerator & freezer, sump pump, furnace or boiler, select lights, and sometimes internet & select outlets.
You’ll turn off all the non-essentials at the breaker, and cover what matters most.
Portable vs. Standby Generator
Due to the lower cost, a portable generator setup is a great starting point. It just requires a manual startup and only powers the essentials.
If you want automatic power and whole-home coverage, a standby generator is the long-term upgrade.
