I think the question is terminology.
There is a single ground bus and a single common bus, NOT keeping the two separated in the main box could cause noise.
By removing or leaving the BRIDGE between the two (common and ground bus) they become one or removing it splits the two buses. It is a VERY common practice, to see a jumper between the two.
It may have been an easier way to explain two grounds vs the practice of having a jumper between the two and REMOVING it. He separated the common bus from the ground bus and cleaned the customers main to reflect that.. Older homes you see it ALL the time..
SPLIT the two and remove the bridge..
Load 1 or Load 2, take your pic but NOT both. You can add 6 breakers just hook them ALL to L1 or L2 not both to equal the load (not that much of a load now anyway)
The old SS Class As could suck the pole dry, still do for that matter. 220/240 is a better option for them.
MC is using a step down from 220/240 to a singe common rail of 120 (if I remember correctly) he’s got a different set up than most. Running HD class A on his system would be no problem, but for the common man they may have to split two 120 vac load between L1 and L2 and result in noise.
It’s all about leakage from the ground into common via the main OR subpanel lay out.. Who did what WHERE, kind of thing..
Clear as mud..
