Never understood that myself as a standard domestic appliance would never draw anywhere near 20 amps. I think they assume that the DP switch would have 32 amps flowing through it rather than just the supply side terminations taking the current.That’s how a lot of new builds are done. Although I think there’s a few on here who don’t like using 20A DP switches protected by a 32A ocpd.
