When most people think of a home inspection, they imagine checking the roof, HVAC system, or plumbing. But at Checklist AZ, we know some of the most important insights come from a $10 tool — the humble outlet tester.
Yes, really.
Electrical safety starts at the outlet, and this small, inexpensive device helps us uncover everything from improper grounding to wiring issues that could pose a serious risk.
What Is an Outlet Tester — and Why Is It So Important?
A Simple Tool With Powerful Results
Outlet testers are small devices that plug directly into electrical outlets. They use a combination of lights to indicate:
- Correct wiring
- Open grounds
- Reversed polarity
- Open neutrals
- Other unsafe conditions
At Checklist AZ, we always carry two testers. Why? Because even the best testers:
- Can break from a small drop
- May have burned-out bulbs that give false readings
- Might mislead an inspector into thinking there’s a major problem (like an entire house being ungrounded), when it’s just the tester that’s faulty
Double-checking with a second tester ensures accuracy.
How We Go Beyond the State Standards
Minimum Standard vs. Our Standard
The state of Arizona requires home inspectors to test a “representative number” of outlets — often interpreted as one per room.
But at Checklist AZ, we test every accessible outlet.
That means:
- We don’t move furniture like beds or dressers
- But if an outlet is open and reachable — we’re testing it
This approach ensures:
- No missed safety hazards
- Better insights into wiring consistency
- Peace of mind for buyers and homeowners
It’s Not Just About Plug and Test
Some assume testing outlets is as simple as inserting a tester and pressing the button — but there’s more to it.
We also:
- Verify GFCIs are wired and tripping correctly
- Check if the outlet cuts power to itself, especially with master GFCI receptacles and breakers
- Ensure power is properly restored after reset
This helps us catch issues like:
- GFCIs that appear to trip but don’t truly cut power
- Outlets that have power but lack grounding
- Circuits that have been poorly altered or extended
Outlet Issues Are More Common Than You Think
In Arizona homes — especially older ones or DIY-modified properties — we often find:
- Ungrounded outlets
- Reversed wiring
- GFCIs that don’t function properly
Even newer homes sometimes have overlooked electrical flaws from rushed construction or missing inspections.
When you choose Checklist AZ, you’re not just getting a home inspection — you’re getting a team that checks the details others might miss.
