The neutral conductor is a critical yet frequently undervalued element in low-voltage electrical distribution systems. This study investigates its technical, safety, and operational significance in environments dominated by nonlinear loads and harmonic distortion. A mixed-method approach - combining standards review, field measurements, and a case study - was used to identify common design, installation, and maintenance deficiencies affecting neutral integrity. Results show that triplen harmonics can cause neutral currents to exceed phase conductor ratings, with one recorded instance reaching an overload factor of 156%.
