When can I use '4H' in my new 4X4?

Using 4H to increase stability and traction. What are the consequences if you get this wrong?

Specifically, a viewer asked if it\'s OK to use 4H on wet main roads, or unsealed roads. Essentially, I don\'t think it is, because it will increase driveline wear, and in extreme situations it might break something expensive, and also leave you stranded.
