The Office Facilities Electrical Checklist I Actually Use (7 Steps, Hard Lessons Included)

Who this checklist is for

I handle facilities purchasing for our company—roughly 90 people across three floors. I manage 8 to 10 vendor relationships at any given time and process somewhere between 60 and 80 orders a year. I am not an electrician. I want to state that upfront because half of what follows is about doing the things I can do and paying a professional for the things I can't.

What follows is a 7-step checklist I built after about four years of getting it wrong in various creative ways. It covers the electrical situations that routinely land on a facilities admin's desk: a switch fails, an occupancy sensor acts up, someone reports a "dead" outlet, and a director asks why the breakroom arcade cabinet's controls don't respond. If you're the person who owns these problems, this is for you.

Step 1: Test before you touch anything (learn your non-contact voltage tester)

This is the step almost everyone skips, and it's the one that matters most. A non-contact voltage tester is a pen-shaped device that beeps or lights up when it's near a live wire. Ours cost $22 at the hardware store. I now own four of them because they keep walking off.

How to use a non contact voltage tester without hurting yourself:

1. Test the tester first on a circuit you know is live. If it doesn't chirp, the battery is dead or the unit is broken. Replace it.
2. Hold the tip within about a quarter inch of the wire or outlet faceplate.
3. If it beeps, the circuit is hot. Stop. Leave it.
4. Kill the breaker, then test again. A circuit that doesn't test dead isn't dead.

I spent my first two years of facilities work trusting the breaker labels. Half the labels in our panel were wrong. A $22 tester solved a problem I'd been "managing" for 18 months.

Step 2: If a Leviton smart switch isn't working, run the checks before you order a replacement

Smart switches fail in predictable ways. Before I order a new leviton smart switch or escalate to IT, I work through this list:

• Check the breaker. Obvious, yes, but I've seen three "dead switch" tickets resolve this way.
• Confirm neutral wiring. Leviton smart switches that require a neutral will not power on without one. If you replaced a switch in an older part of the building, this is your first suspect.
• Watch the LED indicator. A blinking LED and a dark LED point to different problems.
• Full power cycle. Ten seconds off at the breaker, then back on.
• Check the app and firmware. Roughly a third of our "not working" reports resolve with a firmware update pushed from the app.

Our maintenance coordinator and I have a standing rule: we do not call an electrician until we've verified neutral wiring and done a full breaker cycle. That rule alone has saved us three service calls at $150 to $200 each. If you ask me, that's the cheapest troubleshooting discipline we have.

Step 3: Occupancy sensors—placement beats spec sheet every time

We installed Leviton occupancy sensor switches in two restrooms and a conference room last year. The spec sheet told us the coverage area and the time delay. What it didn't tell us is that a sensor positioned near a hallway doorway will pick up foot traffic and turn the lights on at 3 a.m. for nobody.

Before committing to a leviton occupancy sensor switch placement, verify:

• Can the sensor "see" through a doorway or window onto a high-traffic path?
• Does the model have a manual override, and (importantly) does the override actually work the way the documentation says?
• Is the timeout realistic for the space? 30 seconds is too short for a restroom. 15 minutes is too long for a supply closet.

This gets into PIR versus ultrasonic detection territory, which honestly isn't my expertise—I'd recommend pulling in an electrician or the manufacturer's tech line for that. What I'll say from a purchasing perspective: order one unit first, install it, and test it for a week before ordering the rest. We didn't do that. We now have two units we're trying to rehome.

Step 4: Match the switch to the job, not the online listing

Here's where I'll say something a little unpopular. When we needed standard leviton-switch replacements for our offices, I didn't chase the cheapest online listing. I called our local electrical supply house.

Why? Because when a switch fails during business hours, I need a model-matched replacement within the hour, and I need someone to confirm what I'm holding is what I ordered. The online listing that saves $4 per unit costs me a half-day verifying whether "Leviton Decora 15A model X1234" is the same as "model X1234-A." The electrical supply house charges maybe 15–20% more. That's a premium I pay happily for certainty.

Speed, accuracy, price. On a live failure, pick two, and price is the one you drop.

Step 5: Know the line between facility maintenance and "call the electrician"

The line for us:

• Call an electrician: panel work, new circuit runs, anything opening a wall, any work in our server room or kitchen.
• Handle in-house: replacing a switch or outlet on a confirmed-dead circuit, replacing a cover plate, resetting breakers.

I'm not a licensed electrician, so I can't speak to code compliance in your jurisdiction. What I can tell you from a purchasing perspective is this: the boundary matters because on the wrong side of it, you're not saving money—you're creating liability, and liability is expensive to unwind. When in doubt, get the quote.

Step 6: Track the "weird stuff" as its own category

Not everything in an office is a switch or an outlet. We have a breakroom arcade cabinet—long story involving a team-building budget and a very persuasive IT director—and the arcade control panel (the button-and-joystick assembly) wears out faster than the coin mech ever did. It's not a Leviton problem, but it's an electrical problem, and it needs its own line item or it falls off the radar entirely.

The same logic applies to the maintenance on our service van. The 351W spark plug wires on a company truck are not the kind of thing I buy from an electrical supply house, but they're an electrical failure when they go, and my "confirmed delivery date" discipline applies identically when I'm buying auto parts. Every office has one or two categories of "other" that don't live in the facilities manual. Write them down. Track them separately. The thing that wrecks a quarterly budget is a forgotten category that suddenly needs $800 of attention.

Step 7: When it's urgent, budget for the certain option

Here's my one firm opinion. When our front-desk circuit failed in July 2024, we had two quotes:

• Electrician A: $180, "probably tomorrow, maybe Thursday."
• Electrician B: $340, guaranteed by 2 p.m. the next day.

We paid for B. The downtime cost—three people without computers, a front desk phone that didn't ring, a client meeting we nearly had to move—was probably $900 in lost productivity, and that's the conservative estimate. Calculated the worst case: B failed to show, and we'd have lost $160 and been exactly where we started. Best case: back to normal a day early. The math wasn't close.

I know the extra fee feels excessive. I've paid $400 in rush shipping for a $60 part. But when your job is making sure things work, the certainty is the product. The part is just what the invoice line says. The vendor promising "probably tomorrow" isn't cheaper—they're just borrowing your risk without telling you.

Common mistakes I've made so you don't have to

• Testing a voltage tester on nothing. Test on a known-live circuit first. Dead batteries fail silently, and that's the only failure mode that matters.
• Installing occupancy sensors near heat sources. Space heaters, coffee makers, and heating vents will trip them constantly (surprise, surprise—that one cost us a week of complaints).
• Buying smart switches in bulk before testing one model. Compatibility with existing wiring varies more than the marketing suggests.
• Choosing the "probably" option when you have a real deadline. Cost the downtime, compare, then commit.

This checklist was accurate as of Q4 2024 for how our office runs its facilities purchasing. Leviton's product line changes, pricing shifts, and local electrical codes are set locally—verify current requirements with your own electrician or authority having jurisdiction before relying on any of this. I learned these habits over the last four years; the landscape has probably moved since. Note to self: revisit this list every January, along with the panel labels.
