Well Made For Up To 30 Amp Use
I do like for quality of this cord for use as 249 volt for use of medium EV charging speed on my dual voltage EV charger. I will pull around 15 to 16 amp on 20 amp plug. Remember; I will treat it for green as white as the neutral ground on one wire. The former solid white wire will become red as 'Y' live plus Black is 'X' live wire only for 240 volt.

Solidly built heavy duty cord
Needed to replace/beef up a heavy duty table saw cord. This cord is plenty beefy for large 220V shop tools and locks into the receptable solidly, and has some extra length.

Sturdy wire for the Tempware electric garage heater.
Just what we needed for connecting the 240Volt 7500 watt heater. Works like a charm.
