AFDDs are a massive fraud

[Cookie]

Derailed another thread with AFDDs, so I am starting this one. I will simply say that UK RCDs and MCBs provide arc fault protection as is. UL not only knows that, but extensively researched UK power systems in an effort to emulate the very same concept 40 years. One the simply fact (growing concern) that the US National Electrical Code does not prohibit a maximum earth fault loop impedance.

arcing is the result of heated connections

I think it's vice versa

This is my first post and last on this thread.

Every time I look to see what’s new in the posts. This one is top.

I’ve read it and it’s repetitive and boring.

Enjoy.

I was referring to his post though where he states this.

Yes it's a prevalent strategy here Vortigern...slow a process as it may be....



a daily affair for most sparks here.....

The size of those terminals !
(Have torque "wrenches" been specified yet ?

What widget exists? What are you referring to here? Your posts are like riddles sometimes.

And if arcing is the result of heated connections, then surely a device which detects this arcing is a good thing? Note, I am not necessarily saying that AFDDs do this successfully, that is a different argument.

Please , let's not allow this issue into the political rathole of cognitive dissonance PEG. We really are serious in our quest to give a 'heads up' herre

Was just required in the 2017 NEC

110.14 (D)

(D) Installation. Where a tightening torque is indicated as a
numeric value on equipment or in installation instructions
provided by the manufacturer, a calibrated torque tool shall be
used to achieve the indicated torque value, unless the equipment
manufacturer has provided installation instructions for
an alternative method of achieving the required torque.

And if arcing is the result of heated connections, then surely a device which detects this arcing is a good thing? Note, I am not necessarily saying that AFDDs do this successfully, that is a different argument.

Assuming it doesn't catch fire first... At the end stage the tempratures are already obscene.
