No, using a higher gauge wire will not restrict the amount of current an appliance draws. The amount of current an appliance draws is determined by its design and power requirements. Changing the gauge of the wire will not alter the power consumption of the appliance.
The gauge of a wire primarily affects its resistance and current-carrying capacity. Thicker (lower gauge) wires have lower resistance and can carry more current without overheating. Thinner (higher gauge) wires have higher resistance and are suitable for lower current applications.
Using a higher gauge wire than necessary for an appliance can be counterproductive and inefficient. If the wire is too thin for the appliance's power requirements, it may overheat and pose a fire hazard due to the increased resistance and inability to handle the current demand.
To ensure the safe operation of your appliances and electrical devices, it's essential to use the appropriate wire gauge as recommended by electrical codes and standards. If you want to limit the current drawn by an appliance, you should use a current-limiting device such as a fuse or circuit breaker rated to the desired current level. However, tampering with an appliance's current draw without proper knowledge and understanding of its electrical components can be dangerous and is not recommended. If you have concerns about an appliance's power consumption, it's best to consult with a qualified electrician or the manufacturer.
