Time delayed 100mA RCD

[Sb8389]

Hi guys
Quick question
Does anyone know the max trip time for a 100mA time delayed RCD

The time delay is purely protecting the internal tail links in the metal consumer unit.
The consumer unit has 2 30mA rcds in it as stated by the OP I think.
So using a time delay 100mA on a domestic split load board in place of main switch.

Is that what you mean or i may be babbling?

Pretty much; S Type can only be used for a distribution circuit, although I might be wrong? OP was just asking for min/max times of S Type.

Yeah he did but as usual the thread went elsewhere

Time delayed RCDs are used for discrimination.
If the upfront RCD was not time delay, then a fault which would cause a downstream device to trip would most likely also cause the upfront RCD to trip.
Might as well only have the one RCD for the whole installation.

I understand that spinlondon, just wondered why there's been so many posts, when the OP just wanted 'the max trip time for a 100mA time delayed RCD'.
