This looks like a type H-39, but I can't tell if it's 125V, or 250V. A coworker sent the picture and they didn't test for voltage. Is there anyway to tell what kind it is without testing it? Is it even an H-39?

  • Could you get a better picture? That image is so dark and blurry that it is hard to make out the socket. But it looks closest to the H-39 (outward tab and longer hole next to it.) – Jon May 1 '18 at 20:26

  • This is the only picture he took. I agree that it matches rows 1 & 2, but I was wondering if there was a way to determine if it's 250V or 125V without testing with a DMM. I don't believe it's possible. – EEKeefe May 2 '18 at 11:32
  • What is the diameter of the outlet , I have some of these at my plant same pinout with both 125 /250v amperages 20-50 range. If in a residence I would be expecting 240v, if in a older business it could be low voltage 3 phase. – Ed Beal May 2 '18 at 16:26

From everything I can find 1 and 2 are the same receptacle. It's just a matter of application enter image description here

So in answer to your question NO. you need to test it to find out it's apllication.

Sorry I couldn't be of any help.

  • That's what I was thinking was the answer too. Thank's for the help! – EEKeefe May 2 '18 at 18:00
