Not sure if you’re familiar with the term inrush current? It refers to a high level of current that’s drawn from electrical loads for a short period of time upon start up. Like usually for less than a second. Basically, a standard 120 volt 15 amp or 20 amp breaker isn’t designed to see that kind of current, so it usually thinks there’s a fault and trips.
When you get into multiple large light grows they usually use a specific controller. I believe titan controls is the first name on horticulture lighting applications, if you wanna check them out. They’re not completely necessary, but a typical way of combating inrush current issues. There are some other exploratory ways though.
I have started two large drivers from a 20 amp circuit no problem. Whether you’re able to do all four is kind of a crap shoot. You can certainly try. I just wanted to point out that it could potentially be a problem before you were balls deep and a $1000+ bucks in. Running off a different circuit or circuits is ideal, you just have to be careful with the extension cords obviously. You can try staggering timers by a couple minutes too, but getting last set to fire still has to happen with circuit partially loaded.
