Quoted from GamerRick:Well I’m glad I read this I do have 20 Amp circuits on all the plugs in my game room, but I didn’t realize it was bad to start them all at once as long as you didn’t trip the circuit. My friend is also telling me right now this is bad lol so I’ll change it. Another good tip from Pinside.
you guys are talking about "inrush" ( i am not an electrician either but i will ask my electrician next time i see him about this) inrush usually only applies to items with compressors or motors ( fridge,freezer,waterpumps) pins on the high side draw 2.4 amps, using the 80% rule you could run 6.6 pins on one 20amp service. i have 4 machines i run off a 20amp service that is on a relay contactor that all come on with a wall switch. my shop is set up the same way but 4 20amp services for 6 pins each.

posted from Vid1900 "HOW MANY GAMES ON A SINGLE CIRCUIT BREAKER?
===========================================
By now you have probably heard that commercial arcades put 6 pinball machines on each 20A circuit.
How did they come up with that formula?
The National Electric Code wants circuit breakers to see 80% of their rated load. So for a 20A breaker, the ideal number is 16 amps.
Most pinball machines draw about 1.6 to 2 amps peak.
Some pinball machines with a ton of lamps may even draw 2.4 amps.
If you take any random 6 pinball machines at an arcade and measure their amperage draw at the breaker panel, you see that each breaker is seeing ~13 amps. Well under our 16 amp goal.
In your home, where you don't have to worry about employees moving games around and messing up your breaker loads, if you measured a 13 amp draw on a circuit, you could safely add one additional game and still be under your 16 amp target."
