continuity clarification

andy, i don't think it's a question of him not having done the calcs., but more that he needed to know what the question wanted.

Well I covered insulation resistance testing in one of books but I don't remember having to use that formula. I'll have to recap

Andy, well spotted. It should have been a 5 in my original post

Just a reminder that the final figure will always be lower than your lowest original value when doing parallel calcs like this - just a quick way to check and make sure you haven't gone obviously wrong somewhere.

thanks everyone for the help

So, I’m supposed to say what action should be taken if any.

Apart from the obvious safety precautions and use of correcttester and correct voltage I cant think of anything else to add.

The reading seem ok?? they are quite varied but I think that’snormal within different circuits

They are all above 1megaohm

I think personally, although the guidance states anything less than 2ohms should be investigated, I'd probably investigate a reading as low as this.

Well then all seems ok as the lowest reading is 5

TUT TUT, HT, you left the Meg out. :tank:
