So, could you have more than 1 power supply run in parallel, both supplying the same set of wires, so he could just have more than one power supply and not have to rewire?
How much power are we talking, is the current carrying capability of the wire a consideration here?
Current carrying capability of the wire could be a factor, likely not. You could substitute a larger transformer. Running two in parallel is another option. There are three #55 lamps each drawing .41 amps plus two #51 lamps each drawing .22 amps for 1.67 amps draw per wallbox. This is at 6 volts, and an autotransformer steps down the 24V supply so the load at 24V is about 0.4175 amps, call it half an amp due to losses in the transformer, etc. So ten wallboxes will pull about 5 amps. 18-gauge wire is good for 10 amps so unlikely to be a factor if that's what you're using.
The below replacement LED lamp for either #51 or #55 draws 100mA each, so five would be 0.5 amps at 6 volts, 0.125 amps at 24 volts per wallbox. Swapping to LEDs reduces standby current by a factor of four so ten wallboxes on a string would be fine. They're spendy at a little over $5 per lamp, but cheaper than ripping out the walls to rewire and you won't be chasing burned-out bulbs.
