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.
