Bedroom egress window requirements begin with one common misconception. Most people assume a larger bedroom window automatically meets code. Most people start by measuring the window. The code starts somewhere else. Before grabbing a tape measure, the first question isn’t how big the window is. It’s whether IRC Section R310 requires an emergency escape and … Read more
Closet lighting code requirements are often misunderstood. Many people assume that if a fixture uses LED technology, it can be installed almost anywhere in a clothes closet. The National Electrical Code (NEC), however, regulates more than the type of light source. It also regulates where the luminaire may be installed in relation to the defined … Read more
Do recessed shower lights need GFCI protection? It’s one of the more common electrical code questions I hear, especially when a recessed shower light or bathroom exhaust fan is installed over a bathtub or shower. The short answer is: not necessarily. The key to answering this question is recognizing that the NEC is addressing three … Read more
Bathroom 20-Amp Branch Circuit Requirements seem straightforward until you start asking what else can be connected to them. That’s where the confusion usually begins. One electrician says, “Every bathroom needs its own 20-amp circuit.” Another says, “You can put the lights on that circuit too.” Then someone else insists, “No, the lights have to be … Read more
Questions about a deck beam to post connection come up on jobsites all the time. I’ve seen this argument more times than I can count. A contractor points to a deck that has been standing for 20 or 30 years without a problem. The beam is bolted to the side of a post, the deck … Read more
I’ve seen plenty of arguments over exterior door landings, and many of them start with the same mistake. Someone jumps straight to the measurements before figuring out which code section actually applies. A contractor points at a patio door. A homeowner reads something online. An inspector cites a correction. Before long, everybody is talking about … Read more
One of the most common misunderstandings involving exterior door landings is assuming that every exterior door must meet the same requirements. The IRC does not treat every exterior door the same. That is where many inspection corrections, contractor questions, and homeowner confusion begin. Before looking at landing heights, threshold elevations, or exceptions, you first need … Read more
Does This Garage Stair Need a Landing? The garage stairs landing requirement in IRC R311.7.6 is often misunderstood during inspections. Walk into enough garages and you’ll eventually see the same thing. Many people immediately assume the stair fails because there is no landing at the top. Not necessarily. The IRC contains an exception that specifically … Read more
FMC fixture whip grounding rules are commonly misunderstood in the field, especially when no separate wire-type equipment grounding conductor is visible. A common field example is a short FMC fixture whip containing only black and white insulated conductors with no separate wire-type equipment grounding conductor. That immediately creates confusion in the field because many people … Read more
Continuous load and conductor bundling rules are a common point of confusion in the field, especially when both NEC evaluations apply to the same branch circuit. Many electricians understand the 125% continuous-load requirement. Many also understand conductor ampacity adjustment for more than three current-carrying conductors. But confusion starts when both conditions exist at the same … Read more
