UL 758 vs UL 1015: AWM Standards and Selection

In industrial control panels, data center racks, and electronic equipment wiring, UL 1015 and UL 758 are often mentioned together. Many engineers and sourcing teams treat them as parallel standard options, but in reality, they are related as a “parent standard” and a “specific product style.” UL 758 is the framework standard for Appliance Wiring […]

What Is Romex Wiring?

If you’ve ever done any electrical work on a house in the US or Canada, you’ve probably heard the word “Romex.” An electrician might say, “Run some Romex over to that box,” and the hardware store might list it right next to NM-B. But if you ask someone what Romex actually is, you’ll often get […]

Data Center Cabling: Building a Reliable Physical Layer

Data center cabling is the physical backbone that connects every IT device. It carries power from the utility entrance to the rack and every data packet between servers. As AI workloads push rack power from 16 kW to 246 kW, cabling is no longer a background utility; it directly determines power delivery capacity, cooling efficiency, […]

XHHW-2 Cable for High-Density AI Data Centers

AI data center power density is rising faster than anticipated: rack density grew from 16 kW in 2025 to 27 kW in 2026, with next-gen platforms targeting 250 kW+. Global demand is projected to reach 132 GW by 2026 and 290 GW by 2030, making cable selection critical. XHHW-2, a UL 44 listed XLPE-insulated building […]

Solid vs. Stranded Wire Selection Guide

Wire selection often overlooks conductor construction—solid or stranded—which affects installation, termination, fatigue life, and reliability. Solid wire uses a single core: rigid, easy to terminate, for fixed installation. Stranded wire uses multiple thin strands: flexible, vibration-resistant, for moving equipment and continuous flex. Neither is universally superior; wrong choice causes routing issues, breakage, or premature failure. […]

XLPE Insulation XHHW-2

Aluminum vs. Copper XHHW-2 Cable: Applications and Selection Guide

XHHW-2 is the standard building wire for North American commercial and industrial projects. Its XLPE insulation provides a 90°C dry/wet rating, making it suitable for conduits, cable trays, and outdoor exposed runs. But XHHW-2 ships with two conductor options: copper and aluminum. Both share identical insulation and voltage ratings, yet the conductor metal determines ampacity, […]

SJT, SJTW, and STW Portable Cords: Selection Guide

In industrial equipment power, temporary construction site wiring, and outdoor equipment connections, portable cords are consumables—but not disposable. From the same batch, some cords stay flexible for two or three years, while others harden, crack, or break at the bend within three months. SJT, SJTW, and STW are the three most common portable cord types […]
