Anyone who would suggest that others should sustain an electrical injury or be sorted out by the Darwin Process should be ashamed of himself.

Chill out Jim.
I don't think there is anyone on this board other than you that would think John meant anything reprehensible with his comment.

Good thread Epete. It will stick in my mind next time I look at similar set up.

Well said RRS_Dave. Few have worked as hard over the years to educate thermographers about electrical safety than John. The righteous indignation falls a little flat.
These comments are a blemish on an otherwise outstanding thread on Pete's posting. Thanks to all who've posted constructively on this topic. Thanks for kicking this off Pete--I've learned a lot; including the thought process to sort through and tackle a challenging IR problem like this.

Greetings all,
Epete, this was in interesting exercise. So did you install any IR inspection tape or paint on your inspected terminations? This thread made it very clear for me just how hard it can be to take accurate readings on bus bars and lugs. A well designed IR program should include the upfront investment of marking inspection points with high emissivity targets. John posted a great picture for any program to aspire to. I’ll be checking on it at our site now; and sharing this thread with the group.

I second Electricpete's comments and recognize that John has shown himself to be of high caliber and very helpful.

It was very easy to me anyway to keep his comments in context and realize that he was pointing out how really silly ( politically correct for stating how asininely stupid ) some folk can be.

John thanks for your ability to come down to our level. We all know the inherent dangers of working around live equipment and a little humour now and then allows us to keep our sanity.

I work in a motor shop, and we see failures due to looseness in the crimp more often than not.

Personal experience from our core loss tester.... we run 1000 amps through the lead, and if it's not crimped well, the insulation starts smoking at the lug. Check your crimp.

Also the wires in the lug may have some corrosion, creating limited contact. Cause for extra heat.
