Do sit-stand desks require a special electrical outlet or dedicated circuit?

No — standard electric sit-stand desks plug into a standard 120V outlet (in the US) and draw 2–5 amps during operation, which is well within the capacity of any standard 15-amp circuit. You don't need a dedicated circuit, a GFCI outlet, or any special wiring. The desk draws very little power during normal operation (less than a laptop charger) and essentially zero power when idle.
