[QUOTE="Sidewinder, post: 210065, member: 9512"] A 230V rated device is just that rated to 230V, if you stuff 500V wrt earth then you are putting an overvoltage on the device, there may be a clever unit somewhere on the circuit dumping the overvoltage as it is seen as a fault. I don't know the install so I can't give you an exact answer! Is there an rcb or an mcb protecting the circuit, are there em lights on it, are the lights switch start of hf, are there any discharge lights on the cct (i.e. other than "normal" fluoros? This voltage will shifty down the live through the connected loads back up the neutral straight to earth hence your short, even if none of the above are true. [/QUOTE]
