Which of the following is a sign that an electrical system may need upgrading?

• A. Presence of ceiling fans
• B. Use of circuit breakers instead of fuses
• C. Frequent use of extension cords
• D. Installation of LED lighting

Answer: (C)

The indication that an electrical system may need upgrading is frequently indicated by the use of extension cords. This is often a sign that the existing electrical infrastructure is inadequate to meet the current power requirements of the household. Homeowners may resort to using extension cords to power devices or appliances in locations where outlets are insufficient or do not exist, which can pose safety hazards such as overloads or potential fire risks.

In a properly functioning electrical system, there should be enough outlets, and they should be appropriately rated for the devices being used. If extension cords are being used regularly, it suggests a lack of adequate permanent wiring or outlets, which signals the need for a review or upgrade of the electrical system to ensure it can safely and effectively support the electrical needs of the home.

The other options do not necessarily indicate a need for an upgrade. Ceiling fans are common and do not by themselves suggest inadequate capacity. Using circuit breakers instead of fuses is a modernization of the electrical system that generally indicates improved safety rather than a need for an upgrade. Lastly, the installation of LED lighting is actually a sign of energy efficiency and modern practices, which tends to be an upgrade in itself rather than a sign of inadequacy.
