What amperes rating is permitted for a mobile home supply cord equipped with gas or oil-fired appliances?

  1. 30

  2. 40

  3. 50

  4. 60

The correct answer is: 40

For mobile homes, the National Electrical Code (NEC) provides specific requirements for the amperage ratings of supply cords. The correct amperes rating permitted for a mobile home supply cord equipped with gas or oil-fired appliances is typically 30 amperes. This is based on the considerations for safe and effective operation of the appliances typically found in these mobile homes. A 30-amp rating is sufficient to handle the electrical load necessary for the appliances without risking overheating or exceeding the supply cord's capacity. Higher ratings, such as 40 or 50 amperes, may be suitable for other types of installations or appliances that require more power, but for mobile home setups with gas or oil-fired appliances, 30 amperes is the appropriate and safe choice according to established codes and standards.
