Schnider type AC RCD passing type A rcd test.

Alan B

Wonder what your thoughts are on this.

Installing an extra cooker connection point on an existing circuit. the circuit is protected by a 80A type AC rcd and 32A MCB.

It's going to be powering an oven plus an induction hob to be added, so should be on a type A RCD.

Problem is that Schneider only have  a 63A type A rcd for over £100 before vat.

But interestingly the type AC device tripped in 19mS  with a *1 type A rcd test.

So I am thinking maybe I don't need to worry about changing the RCD, what are your thoughts.

If I do change I will probably have to go for an RCBO

  • I would agree with your findings. I reckon the D.C. lock risk has been somewhat over done, and that in practice, you have nothing to worry about. So long as your test result is repeatable and recorded you should be fine.
