You could run 2 L3+ on a 20amp 120v circuit, but you could only run one on a regular 15amp circuit.  Well you could run 2, but you will likely end up serving drinks and food to a bunch of guys with a big red truck, sirens, and some spotted dogs... LOL

I am also looking at building out some 220v circuits and trying to figure out the plug, and PDU configurations etc for this.
