Weekly digest #91: common code violations spotted

Five violations we keep seeing this week

Pulled from inspector callouts, field photos, and questions routed through BONBON this week. These are not exotic failures. They are the everyday misses that cost a re-inspection or a callback.

Run through them before your next rough-in walk. If any of these show up on your last three jobs, tighten the checklist.

1. GFCI protection missing in laundry and utility areas

The 2020 cycle expanded 210.8(A) to cover laundry areas, and the 2023 cycle kept it there. We are still seeing standard receptacles behind washers and in utility rooms within six feet of the laundry sink. Inspectors are failing these on sight.

210.8(A)(10) covers laundry areas. 210.8(A)(7) covers within six feet of a sink. If the room has both, both rules apply, and the branch circuit needs GFCI from the first outlet on.

• Laundry receptacle behind the washer: GFCI required, no exception for the appliance.
• Utility sink circuit: measure six feet from the sink edge, not the faucet.
• Dead-front GFCI at the panel is fine if the run is clean and the reset is accessible.

2. Tamper-resistant receptacles skipped on "utility" spaces

406.12 is broader than a lot of techs remember. Dwelling unit receptacles in nearly every 15A and 20A 125V and 250V location need to be tamper-resistant, including hallways, laundry, basements, garages, and accessory buildings associated with the dwelling.

The exceptions are narrow: receptacles more than 5.5 feet above the floor, those part of a luminaire or appliance, a single receptacle or duplex for two appliances in a dedicated space behind the appliance, and non-grounding replacements under 406.4(D)(2)(a).

If the receptacle is in a dwelling and you cannot quote the exception number from memory, install TR. It is cheaper than the trip back.

3. Bonding bushings missing on concentric knockouts

250.92(B) requires a bonding method other than standard locknuts where circuits over 250V to ground pass through concentric or eccentric knockouts that are not listed for bonding. This also applies to service raceways regardless of voltage.

The common miss: a 120/240 service with EMT landing on a meter can or disconnect through a concentric KO, bonded with just a locknut. That fails. You need a bonding bushing with a jumper, a bonding locknut listed for the purpose, or a listed fitting.

• Service raceways: bonding required regardless of voltage.
• Feeders over 250V to ground through concentric/eccentric KOs: bonding required.
• Punched KO with no rings left: standard locknut is fine. Verify before you add hardware.

4. Working space encroached by equipment, not people

110.26(A) is usually taught as "three feet clear in front of the panel." The violations we see are not about people standing in the space. They are about stuff living in it: a water heater, a sump, low-voltage gear, a shelf of paint cans.

The working space is dedicated. 110.26(B) says it cannot be used for storage. The depth, width (30 inches or the width of the equipment, whichever is greater), and 6.5 foot height all have to stay clear. Panels in finished basements get flagged for this constantly once the homeowner moves in, so note it on the job before you leave.

Take a photo of the clear working space at final. If the homeowner stacks totes against the panel later, the photo proves you left it compliant.

5. AFCI extension rules on renovations

210.12(D) and the extension language in 210.12(B) trip up a lot of remodel work. If you extend, modify, or replace branch-circuit wiring in an area that would require AFCI for new work, the circuit needs AFCI protection. Swapping a device does not trigger it. Pulling new cable to add a receptacle does.

The practical read for kitchen and bedroom remodels:

1. Adding a receptacle to an existing circuit: AFCI required on that circuit.
2. Replacing a failed device with no wiring change: not triggered.
3. Replacing the first outlet on the circuit with a listed OBC AFCI receptacle is an accepted method when a breaker swap is not practical.

Check the AHJ before you rely on the OBC receptacle method. Some jurisdictions want the breaker regardless.

Quick field checklist

Print this, tape it inside the van door, or pull it up in BONBON before the inspector arrives.

• GFCI: laundry, utility sinks, garages, basements, outdoor, kitchens, bathrooms. Measure from the sink edge.
• TR: every 15A/20A 125V and 250V receptacle in a dwelling unless you can cite the exception.
• Bonding: service raceways always, over-250V feeders through concentric KOs always.
• Working space: 30 inches wide, 36 inches deep, 78 inches tall, nothing stored in it.
• AFCI: any new wiring in a protected area, not just new circuits.

If one of these bit you this week, you are not alone. Send the photo and the article number to the crew chat so the next hand does not repeat it.
