In traditional installations in the UK the voltage between an appliance frame along with the earth by itself during a zero-impedance fault features a hazardous magnitude: it would be decreased to about 50 % of your 230 V line-earth voltage, and that is well over the fifty V commonly acknowledged as Protected for an ac program, or it'd be approximately 230 V inside of a TT system with a lousy earth electrode to the set up.
