Since going from wanting one pin to a ever growing collection......
(14 right now), I need to upgrade my wiring as the pins share a
common circuit with a mini fridge & a dehumidifier. If I have more
than 2 DMD pins going at once & the fridge compressor or the
dehumidifier kicks in, I get resets on the pins. I have a 200 amp main
service, so adding additional circuits won't be a problem.

Right now everything is on one 20 amp loop.
(The room really wasn't designed as an arcade initially)

How much current draw does a modern DMD pin use ?

If I run more 20 amp circuits, how many pins are I going to be able to
run per circuit ?

Since Google search for the groups is a joke lately I'll cut you some slack.
:-)))

Figure 2.5A per pin at 120V.

20A circuit at 80% rated can handle 6 pins easily with no other loads. If
you add other loads those need to be taken into consideration.
15A circuit figure 4 pins per circuit. Yes you might be able to sneak one
or two more per circuit...this is just quick rules of thumb.

Remember motor loads have high inrush when first started (locked rotor is
about 7 times full load amps). The high inrush can cause the +5V watchdog
circuit to drop below it's threshold and reset the pin.

Take it from Mike. That's what you want to do.

You can search Google and see all the time and effort that he and I
put into getting this data (we worked seperate on this and came up
with the same answer). I think I put more effort into answering the
questions about it more than getting the data, but anything to help
out. We actually mreasured a host of pinballs to get the 2.5 amp
average.

20 amp = 6 pins, 12 ga wire
15 amp = 4 pins, 14 ga wire

The above does not count in long wire runs, so come back if you are
going more than 100 feet.
