Grenfell tower electrical "expert"

[johnduffell]

For some reason, the grenfell tower inquiry has got an american electrical expert to comment on the electrical cause of the fire. And he doesn't seem to know a lot about BS7671 etc,

Firstly he thinks you can't trip an RCD after the MCB has tripped of a given circuit (presumably they have DP MCBs over there?), and secondly he thinks it's very improbable to trip an RCD and MCB simultaneously. Therefore he thinks most likely this happened in the first few minutes of the fire:

He also seems to think a more "violent" short circuit would be more likely to start a fire because the MCB wouldn't trip quick enough. And he uses the total clearance time (rather than pre-arc time) to decide whether there's discrimination between a B32 and a 13A fuse.

They could have got any british electrician in and they'd have done a better job than this guy!

no but your post was 100% innuendo, I'll agree there are so many problems with this country and so many positive things, but I don't think 13 out of a million people are fraudsters is really going to win any awards for being anomalies.
I'd rather shine a light on the people in power than the people at the bottom. DM is not the only structure of power keeping the many in order by keeping us blaming each other.

I lived 5 mines walk from the Grenfell Tower for 11 years there was a lot of subletting going on in the area, I bet you don't live in London yourself as there are so many fiddles going on by certain people to gain an advantage, I remember given up on a disabled permit for my Mum, just saying.

your bet is irrelevant and admittedly my council owned flat was Westminster rather than K&C however everyone I knew there was lovely. But anyway we can agree to disagree! This thread is about the electrical expert anyway.
