2020 seems to be requiring the dryer to be on a GFCI. It also seems to be saying if you have 240v receptacles in the garage for compressors, welders etc, they need to be GFCI.
The article in EC&M seems to be saying the objective is to put everything on a GFCI or an AFCI maybe both since some of the examples they use are already required to be AFCI. The reality is all they really need to do is redesign the AFCI breaker with 5ma GF protection instead of 30ma. I think the goal is to make the simple circuit breaker obsolete.
