Reading an article by Jestine Yong, and he said cold ground is chassis ground. I think I get that.
But he referred to hot ground as being different.
Is that what we call neutral?

Thanks

 

Never heard of that expression, I suspect he has his own interpretation of a earth grounded conductor to set up a neutral.
We will have to add it to the list!

Me also, never heard of hot and cold ground.

 

A ground gets hot when there's a fault?

 

Ground wire hooked to either the hot or cold water pipe?

 

A ground gets hot when there's a fault?

Or a ground that you get zapped from 'cos it is not actually grounded?

I think something was lost in the translation.

 

I too have Jestines Ebook and my interpretation of hot ground is ground provided on the mains side and cold ground is chassis ground or secondary ground. Hope that helps. Hot ground = high voltage side. Cold ground = low voltage side.

 

Still doesn't make much sense, if this is with reference to a ground reestablished on a transformer secondary, it normally should be directly connected or referenced to the primary side ground.
One of the better books on grounding is the one by Eustace Soares, and is used as an international reference by the IAEI, International Assoc of (Electrical) Inspectors.

Here is an example of hot/cold ground.

The chassis has a 'hot' ground reference on the primary side and a cold ground reference on
the secondary side of the power supply and the rest of the
chassis.

We believe you @aniculav

It's just when a reference makes up his/her own non-standard terminology is when communications and understanding is stifled.
