don't really think it's an issue though, not heard of any petrol stations blowing up in the UK.
Don't start giving these ISIS Jihad types any ideas for fooks sake!!!

Do you mean Ra
As silly as it sounds it has been taken in to account. Many chemical plants and gas facilites do have a police presence, as is in the Grimsby area.Don't start giving these ISIS Jihad types any ideas for fooks sake!!!

should do, although it can be quite sandy in placesCheers. Do you think I would get down on my Armstrong? (off-road bike, road legal though)
That's what happens when the old bugger doesn't put his glasses on.
Many thanks for correcting me kind sir.
Just wish they could come up with some decisive information or even come to a reliable conclusion as to what makes a max value stable and then at what point its not.
I have corrected TT system readings above 400 ohms.
And yet the 30ma rcd's protecting those circuits have, under test, operated within 40ms/200ms no problems.
If un-stability is a science it needs practical clarification so that we have a definitive cut off value that all adhere to with no grey areas.
In the mean time I will continue to go with 100 ohms purely because logic dictates its a safer bet than 200 ohms.
No other reason, and if someone proved conclusively that below 200 is still a safe option then so be it.
Thats got to be one of the most illogical statements I've ever seen on this forum. You might as well go with 1000 because it's safer than 1667!
We should have a poll to find out the answerDoes everything need to be a poll?
We'll be having designs put to a poll soon!
