A:Answer The wattage and voltage is not relevant. It matters however how many amperes (amps) are drawn with the unit turned on and baking. According to the manufacturer this unit uses about 900W, 110V and draws 13 amps. If tracing the wiring from where the unit is plugged in to the breaker box reveals a 20 Amps circuit breaker you should be fine (in theory). If power cord/prongs of the unit gets hot after in use or if the circuits breaker trips then the electrician needs to upgrade your breaker/wiring. Lastly, a dedicated electrical line should not be required if your breaker is 20 Amps or more.
