It is not condescending.I am not Lambda but this is quite condescending... Please let's be nice to each other. I am an engineer myself and I did not fully understood all you said neither. We all have our specific area of expertise and don't have experience on everything.
I've been called a liar when I pointed out that a member claimed R is frequency dependent. I give respect as long as I receive it. I try to explain myself, answer questions posed. Many do not, they ignore them and attack. It is a pattern.
Condescending is mocking my grammar, or saying it's not a 'relay' when the mfg. calls it a relay and then sticking to it.
A relay relays information:
Switch state, a switch operates a relay
Current magnitude to a contact
Vibration to a contact
Etc.
It takes an input and generates an output, typical a set of dry contacts.
Then perhaps he should not offer Google opinion outside his area of expertise.
One should have to submit a resume and be vetted before commenting of engineering matters, especially safety related.
He said an ungrounded xfmr sec N is safer than grounded.
All Codes, UL, engineering principles and standards say otherwise. It is dangerous misinformation that could result in injury or property damage if someone heeds his advice and disconnects it.
And he doesn't even know why.
If a xfmr with an ungrounded N faults L to frame what happens to the N?
And the N and frame are touched?
As in a damaged cable, plug, etc.
I'm not going to offer medical or legal advice. Why should safety engineering be different?
