Some installations make you stop and ask, “How did we end up here?” This inspection photo shows a breaker panel beside a shower. The original inspector also reported a toilet directly below and in front of the panel, obstructing the working space. Here’s how this location compares with the 2023 NEC: 🔹 240.24(E) — Bathroom locations: Overcurrent protective devices, other than supplementary overcurrent protection, are prohibited in bathrooms, showering facilities, and locker rooms with showering facilities. 🔹 110.26(A)(1) and Table 110.26(A)(1) — Working-space depth: For typical residential equipment operating at 120 volts to ground, the minimum clear working depth is 3 feet. A toilet cannot occupy that required space. 🔹 110.26(A)(2) — Working-space width: The clear working width must be at least 30 inches or the equipment’s width, whichever is greater, and must allow equipment doors to open at least 90 degrees. The panel does not have to be centered within that width. The lesson: Panel placement matters just as much as the wiring inside it. We need a suitable location and clear space to operate and service the equipment. This photo was originally posted in 2009. We’re using the 2023 NEC as today’s learning reference, rather than assuming which rules applied when it was installed. What catches your eye first?
