Not where I really want to be
Bon voyage rule of 6 swipes of the hand for a service. There are ways to have more than one disconnect for a service but the days of having a panelboard with 6 swipes of the hand is now gone when you adopt the 2020 NEC.

A welcomed, positive change in my opinion !
There have been so many violations of trying to
add as much amperage under those "6 throws"
as possible.

My guess is that the concensus for the 2020
change is to increase the safety factor to not
have as much amperage flowing the
multiple combinations [ read - violations ] of the
"6 Throw Maximum Rule".

Depending on how this is interpreted, this will be a huge problem....

1008.3 Service upgrade. Where the occupancy of an existing
building or part of an existing building is changed, electrical
service shall be upgraded to meet the requirements of NFPA
70
for the new occupancy.
