RCD types

AJJewsbury
Is it just me or are RCD types starting to get silly. After the EVSE discussion I've looked at the data sheets for a couple of manufacturers and collected the following list of RCD types:
  • AC

  • A

  • A EV

  • A KV

  • U

  • F

  • B

  • Bfq

  • B+

  • B NK

  • B SK

  • R (for x-ray/CAT supplies)



Plus 'delay' types of:
  • (none) - instantaneous

  • G short delay (10ms)

  • S proper delay/selective


I suspect type U might now be obsolete, and  Bfq and B+ from one manufacturer might be the same/similar as B NK and B SK from another, but it's starting to smack of people just making things up as they go along.


Anyone found any more?

    I don't know about being "silly" but the subject of the many different R.C.D. types is definitely getting very complicated and confusing. I've given up on juts how they all technically vary.
