300 mA RCD

Hi I have a problem with a 3 phase industrial ironer. main components are (3) inverters roughly 8 amps per phase (24 amps) no further details at this time.the circuit is protected with a C50 Amp MCB feeding a 300mA type B RCD. The RCD has tripped, and now will not reset even with the load disconnected and therefore requires replacement. The ironer is new. what are your thoughts?

    Have you tried testing the RCD on ramp and without the device connected

  • I couldn’t even get it to reset. I disconnected the load cables and it stills Tripped.

  • It’s been sent back to China for tests. Despite what you all might be thinking, this is a reputable brand.
