Ohm’s Law describes the relationship between voltage, current, and resistance in an electrical circuit: voltage equals current multiplied by resistance (V = IR). Pair that with the power equation – power equals current multiplied by voltage (P = IV) – […]
In the hierarchy of fall protection, PPE, sits near the bottom, not the top. Elimination – removing the fall hazard entirely – is always the first line of defense, followed by passive systems, travel restraint, and only then fall arrest. […]
There are words in the National Electrical Code that practitioners use every day without a second thought. “Backfeed” is one of them. What emerged during a Code-Making Panel 4 meeting in the 2026 NEC revision cycle is that even the […]
