Cooper Wiring Devices 5266 – Frequently Asked Questions

1) Will the Cooper 5266 plug fit SJT 14/3 cord, and what cord diameter does it clamp?
The 5266 Ultra Grip plug accepts cord from 0.33 to 0.66 inch in overall diameter, and terminates #18 through #12 AWG conductors. A typical 14/3 SJT cord falls inside that window, so it clamps fine. If your cord jacket measures under 0.33 inch, the strain relief will not grip properly and you need a smaller-range plug.
2) Is the 5266 plug tough enough for a shop floor, or is it just a residential replacement cap?
It's built to extra heavy-duty industrial specification grade, which is the top tier above commercial and residential spec. Housing is thermoplastic polycarbonate with a nylon face body, and the contacts are brass. That combination is what you want on portable tool cords, machine pigtails, and maintenance cord sets that get dragged and dropped, not a light-duty residential cap.
3) How do you wire the Cooper 5266 Ultra Grip plug - screw terminals or push-in?
Back wire with screw terminals. The conductor lands behind the clamp plate and the screw tightens down on it, which gives more contact area than a side-wired loop and is quicker in the field. Three wires total: hot, neutral, and equipment ground.
4) Can I use the Cooper 5266 on a 240V or three-phase circuit?
No. It's a two-pole, three-wire grounding device rated 125V only, in the NEMA 5-15P pattern. For 250V single-phase you need a 6-series configuration, and three-phase requires a different NEMA pattern entirely.
5) What color is the Cooper 5266 plug, and is it straight-bodied or angled?
Straight blade, straight body, in white. A straight body plugs in line with the receptacle, so if the cord has to lay flat against a wall behind equipment, an angled cap is the better choice. For machine pigtails and drop cords, the straight body is standard.
6) How does the Cooper 5266 ship - bulk or individually boxed?
It ships as a core pack. If you're standardizing cord caps across a facility, order by the pack quantity rather than assuming single-unit packaging.
