Good stuff Mark thanks for the info...I've only ever watched the vid with an interest from being in the game in a previous life without knowing the story behind it. Your right, SF6 is nasty stuff, though maybe not as nasty as PCB's which I dealt with breifly when I worked in the industry. Again part of the reason I bailed out .
Cheers

PS, Jason, sorry gone so far off topic with this thread I think your power point will be fine .

it's best to get it checked out and replaced. arcing like this can cause the contacts to fuse together, and can pose a fire risk.

Stay with Reggie and Bazza
If you are in a dark room you wil find most switches will arc (show a flash) when switching load
Try switching the load off before switching off at the power outlet

Have we actually defined the problem - do you get the flash without an appliance connected to the GPO (powerpoint)??
If you get this flash only with an appliance connected, what is the current draw for the appliance - usually printed on the compliance sticker. If no sticker just tell us what the appliance is and we should come up with a rough estimate of load.
If the flash happens with nothing connected - get an electrician immediately! :eek:______________

Jason those flashes are generally harmless, If you have an Inductive load attached to the point then Interrupting the current by switching off the power point will cause a high voltage flashback which has to go somewhere, partly through you, but mostly jump the switch to a lower potential, also note that when you turn a switch off it does not simply break contact but bounces back and forth till it settles and in the case of a substantial current there will be arcing.

I get the same thing in my house....when I pull oot an appliance without turning the switch off especially there is a flash...quite scary really. I dont have a safety switch either and the fuse box is still the old one. An electrician said its been re-wired though? Any ideas?

One flash and your ash
