An RCD is rated 32 A, 30 mA, AC. What does the 32 A rating indicate?

Explanation:
The 32 A marking shows the device’s maximum continuous current it can carry through its terminals. This is the thermal/operational limit for normal load current. It’s not telling you the voltage rating, it isn’t a fuse rating, and the leakage sensitivity is a separate value (30 mA). So the 32 A simply indicates the safe current-carrying capability of the RCD during regular operation.
