New to this site, just got a bit of a problem that i need a little help with.


100 amp 300 ma time delayed RCD feeding DB with 100 amp 30 ma RCD as main sw.

3 phase band saw fed from DB. Saw works fine until dc brake is hit and then main RCD trips. bypassing RCD on DB.

Surely the 30ma RCD should tip before main RCD.

If that makes any sense! any ideas.

cheers

jamesie.
