What is a common characteristic of electric ranges in residential wiring?

Electric ranges in residential wiring are designed to handle significant power loads due to their heating elements and other features, which is why they are commonly rated at 60 amperes. This rating ensures that the range has enough electrical capacity to operate efficiently without tripping circuit breakers or causing overheating issues.

The need for a robust amperage rating in electric ranges differentiates them from lighter appliances. A 60-amp circuit allows for higher wattage use, enabling the range to operate multiple burners and the oven simultaneously. This is crucial for cooking needs in a typical residential setting.

The other options do not align with the typical requirements for electric ranges. For instance, they do not utilize 2-wire connections; instead, they require a 3- or 4-wire configuration for both safety and functionality, especially since they require a neutral wire for certain controls. Additionally, a 15-amp circuit is insufficient for electric ranges, which need dedicated circuits to handle their amperage requirements safely. Lastly, while electric ranges need dedicated circuits, these are not for lighting but rather for their own operation, due to the high load they impose on the electrical system.
