I would like to charge an EV at 10, or even 15A through a GPO that has a power meter attached.

The meter states 5(45)A, and Rated Current (Ib ) 5 A Maximum Rated Current (Imax) 45 A

So, will a lengthy continuous draw of 10A be too much for the meter, or does the 45 A max mean that I could theoretically draw 45 A continuously without ill effects on the meter?enter image description here

    Welcome! Photo or link to datasheet please. – winny Jun 16 '23 at 07:13
  • DRS-201A. Unsure as a new user of I can post a photo yet – cracker Jun 16 '23 at 21:23
  • Yes you can. Click on edit, go to where you want the picture to appear and click on the image symbol. From there you can import it. – winny Jun 17 '23 at 06:26
  • And there's a hyperlink button so you can add a link to the datasheet (not an ad page) for the meter. – Transistor Jun 17 '23 at 08:53
  • There was a very similar question or answer recently, and I think the 5(45)A was most likely for an external CT. Otherwise it might be that the meter can tolerate (and retain accuracy for) brief peak currents of 45A. – PStechPaul Jun 17 '23 at 09:10
  • Yes, I saw similar answer about CT, but couldn’t find anything about rated current. I understand if it’s referring to CT it is accurate down to 5A, but I’m still trying to work out what continuous current I can run through it. I’ve been slowly ramping up from 5A for over 24 hrs – cracker Jun 17 '23 at 09:34
