Seems like a lot of cords now days, even the "heavy duty" or "industrial" jobs are really just 14 or even 16 AWG inside SJTW insulation. Won't stand up to very much abuse and has one heck of a voltage drop at 100' lengths for things like D-handle drills.
I was playing with the idea of making a super-duty cord out of some SEOOW and W/P cord caps until I found a similar one at one of the big-box stores made out of SJEOW.
Is the only difference between junior-service and hard-service the voltage rating?
Is it worth my money to try and make a super-duty cord, or would the SJEOW stand up to use and abuse as well as anything else?
