** Try reading the whole story.

MK state clearly that ONLY the 30mA models are capable of giving good
shock protection.

The 100 mA models are ONLY intended where a 30 mA one cannot be used -
presumably because inherent circuit leakage to ground equals or exceeds
30mA.

MK also state the a 300mA model is PURELY intended for equipment and fire
protection.
